1 Introduction The VT is used to display and input data, to show status messages (for instance, dynamic texts) or alarm messages in machines or plant controlled by a PLC. The VT is a versatile and economic solution because it communicates directly with the PLC using the programming connector without requiring any additional hardware. The VT is programmed using programming software that enables the data to be transferred to the unit's memory. With the characters offered innumerable applications are possible: the generous display area allows the operator to keep a check simultaneously on a large quantity of data (the upper limit varies according to the model). In addition it can deal with up to 1024 alarm or machine status messages. The VT can store up to a maximum alarms (the upper limit varies according to the model, in a buffered RAM), together with the date and time they occurred or passed so they can be subsequently printed out when required, enabling a statistical diagnosis of the faults concerned.

2 General information on electromagnetic compatibility Electronic devices are being increasingly used in automated systems. programmable controllers (like the PLC) belong to this category, as do Man-machine-interface systems (eg the Video Terminal), control systems (eg diagnostic panels), interface elements (eg interface boards) and activators (like inverters). Together with this type of electronic apparatus, you find installed classical electro-mechanical devices like counters, electro-valves, motors etc. Electrical disturbances caused by the operation of these devices can compromise the smooth functioning and the length of the working life of the electronic devices present on the same switchboard or the same plant. To get the best out of both the electrical and the electronic devices it is necessary to reduce electrical disturbance. Laying cables. Remember to lay measurement, monitoring and communication cables so that they are kept apart from power cables. Power cables laid close and parallel to communication cables can cause coupling voltages that are strong enough to disturb or destroy electronic components. Shielding of cables. It is essential to use suitably shielded cables for communication signal connections (total shielding is recommended). The shielding must be connected to the zero potential. Earthing of shielding and electronic circuits. With many devices the "0V" is connected to the earth. The signal ground must be earthed but it is best to separate the ground of the shields and circuits from that of the power circuits. Note that the earth can only perform its function if the "Resistance of the earth circuit" is within the max. limits prescribed. Switching of capacitive loads. The current peaks which occur when capacitive loads are switched on can damage or destroy control devices. Furthermore, the high-frequency component of the current peak can cause serious disturbance in electronic circuits caused by inductive coupling between the connection cables. Switching of inductive loads. When and inductive load is switched off, the magnetic energy stored tends to oppose this, discharging a voltage peak down the line which can damage or destroy the control device. Furthermore, the high-frequency component of the voltage peak can cause disturbance caused by capacitive coupling between the connection cables. The physical structure and characteristics of an inductive load make it impossible to carry out switching without disturbance unless suitable measures are taken. The disturbance can be at least partially suppressed by fitting a suitable disturbance-suppression module in parallel with the inductive load. The disturbance-suppression module must not constitute an additional load during the work phase. Electrical disturbance is propagated both through the connection cables and electromagnetic transmission. If the disturbance is propagated by cable or electromagnetic transmission, it is much more difficult to suppress at the inputs to the units in the danger zone than it is to suppress the disturbance at its source.

Disturbance must be suppressed at its source whenever possible.

2.1 Disturbance suppression circuit with RC

RL

il

C R

SUb

Advantages Disadvantages The residual component has a very low harmonic waveform component.

The best results are obtained by sizing the R/C circuit suitably.

The residual overvoltage can be limited to very low values by optimising the sizing.

Volume directly proportional to the inductance and power of the load.

Switch-off time delay very low. Optimal suppression is obtained as a direct consequence of a significant de-energising delay.

The effectiveness of the disturbance suppression is not affected by the voltage value. No switch-on delay.

The presence of the capacitor causes a high load current peak when switching on (and can cause pasting of the contact if undersized).

Suitable for both AC and DC; no problem with reversed polarity.

The RC circuit constitutes an additional load when used in AC.

No arc (low energy) on switching contact.

Dangerous connections

These two configurations will seriously damage VT components For applications that use the power supply positive connected to PE.

IMPORTANT

The earth of the devices connected to the serial and/or parallel communication ports MUST heve the same potential as the 0V supply of the VT. The circulation of current between the 0V supply and the earth of the communication ports could cause damage to certain components of the VT or of the devices connected to it.

CCFL display LAMP

IMPORTANT

VT550 panels are equipped with a lamp giving backlit CCFL display. This lamp has a limited life.The average life of these lamps depends on the temperature of the

environment in which they work.The maker declares the following for a temperature of 25°:VT550 display STN 20000h.After this time the loss of luminosity may have

reached 50% or even be total.The loss may be much quicker (from 20000h/25000h to 2000h) if the working temperature is close to 0° or above 40°.To increase the life of

the lamp, ESA has created a special bit that switches off the lamp via a PLC command. This feature is only advised for temperatures near the operational limits.

M Battery housing. The battery protects the content of RAM (work recipes) and powers the internal clock (12 microamps at a temperature of 25°C) in the absence of power supply. At the moment of purchase there is no battery in the VT, thus inserting it is a matter for the client.

Battery to be used Size Catalogue code

Lithium 3.6V ½ AA VTBATTERY We recommend substituting the batteries every 12 months. • When the battery Led (situated on the VT keypad) lights up it means that the

battery should be substituted. The content of the data memory will be lost if the battery is not renewed. Apart from this, the VT communicates via the appropriate bit in the VT-PLC data exchange area that the batteries are flat.

• The batteries must be changed with the VT off. The data in the buffered memory are not lost in this phase for at least 15’.

Dispose of batteries responsibly.

30 ESA elettronica

10 Error messages The VT may display on its screen while in operation certain operation error messages or program error messages. The messages are as follows:

NUMBER TYPE OF ERROR DESCRIPTION ERROR 1 Too much data in page: X Means that the maximum number of data per page has been

exceeded in the page in question. ERROR 2 Page not found: X Means that the page X has been called up, but does not exist

in the user program. ERROR 3 Starting page not defined. Means that no sequence declaration has been made in the

program; there is therefore no definition of the starting page. ERROR 4 Data not found: X. Means that the datum X is not present in the database. ERROR 5 Recipe data not found: X. Means that the datum X is not present in the database of

recipe data. ERROR 6 Command not recognised

in page: X. Means that a command on page X has not been recognised.

ERROR 7 Object not found. Means that the object to be displayed does not exist in the page.

ERROR 8 Report not found. Means that the report to be printed does not exists. ERROR 9 Wrong VT in project. This means that the FLASH-EPROM module installed in the

VT contains a project made for a different model of VT.

ERROR 10 Wrong PLC in project. Means that the project which has been transmitted to the VT was made for a different PLC with a different driver

Useful advice for overcoming these errors: • ERROR 1: Erase some date on the page X • ERRORS 2, 3, 4, 5, 6, 7, and 8: Check the project again, there could be errors

there. In these cases it is advisable to use the “Full compilation” in the transmission to VT phase.

• ERROR 9: The FLASH-EPROM must be replaced or erased and reloaded with the correct project.

• ERROR 10:Load the correct driver for your PLC or change the project driver. If you want to transfer a driver or a project when errors 9 or 10 appear on the screen, you have to wait until the VT enters the service page (wait about 17 seconds from the appearance of the error message) and transfer the new driver or the new project. To find out how to transfer the driver or the project, see the sections "Loading the driver in a VT" and "Loading the project in the VT".

If the memory installed in the terminal is not sufficient for your project, the size can be increased by using appropriate expansions. As shown schematically on the rear of the panel the VT has two distinct types of memory, each intended to perform a particular task: • RAM used as data memory ;

the basic data memory present on the VT is: − 8Kb for VT510. − 32Kb for VT520 and VT550. In the case of VT520 and VT550 the capacity of the memory can be increased by applying a supplementary memory module. E.g. if an additional board of 32Kb is installed, the data memory available will be 64Kb, as the base memory must be added to the supplementary memory.

• FLASH EPROM memory used as text memory. It is essential that the text memory be installed. At the moment of purchase there is no text memory module in the VT, thus inserting it is a matter for the client.

13 esa-bus network

34 ESA elettronica

13 ESA-BUS network With the ESA-BUS network you can connect many VTs to a single PLC. The system is made up of one master VT connected to the PLC and to up to 31 slave VTs. To make the network function, the ESA-BUS board must be inserted in the VT that is to be used as master. The job of the master VT is to interact with the PLC on its own account and for the other VTs. Each VT connected in the network must have its own address, unique in that network; there must never be two or more VTs with the same address. The address of the master VT is always 0, the slaves can have addresses from 1 to 31. It is essential that the connected slaves have consecutive addresses, starting from 1 and running to the number of VTs in network (maximum of 31). The master VT carries out the data exchange starting with slave no. 1 and finishing with the last SLAVE declared (maximum 31).

ESA-BUS connection scheme

• Use a single power supply unit to supply all the VTs connected in the network. • The earth connections must all be of the same potential.

IMPORTANT • The serial connection cables of the VTs must be put in conduits separate from

those carrying power cables. • The power cables for the VTs must be put in conduits separate from those carrying

power cables or other industrial devices, which, in principle act as sources of interference (frequency converters, motors, etc.).

ESA-BUS board The ESA-BUS board allows the user to connect the master VT to other VTs called slaves in the ESA-BUS network. At the moment of purchase the VT does not have this board: the customer who wishes to install the board must insert it himself. What to do to insert the ESA-BUS board. • Check that the power is not connected. • Take off the rear cover of the VT. • Fix the plastic stand-off studs (supplied) in the appropriate holes (A), with the

soldered side of the board uppermost. • On the VT break out the covering relating to port COM2. • Locate the strip 5x2 on the VT. • Insert the 9-pin male connector of the ESA-BUS board into the COM2 hole of the

VT. • Insert the male strip of the VT into the female strip of the board and insert the

plastic stand-off studs mounted on the board earlier into the appropriate holes in the printed circuit of the VT.

• Press the board down firmly so that the stand-offs are locked top and bottom. • Now screw the metal screw (supplied with the ESA-BUS board) onto the sides of

the board's 9-pin connector such that the board remains locked to the cover of the VT.

• Replace therear cover of the VT. • Reconnect the power supply.

13.2 Defining the master VT parameters Using the service page, input the address to be assigned to the master VT, that is 0, and the number of slave VTs (maximum 31). Operations necessary for inputting network parameters: • Enter service page using + . • In the case of VT510 and VT520T models press . • Go to field "ADDRESS" using or . • Select the number "0" using or . • Go to field "MAX STATION" (or to field “STATIONS” for VT510) using or . • Select the number of slave VTs connected to the master using or . • Exit from service page by using or + .

Master VT error signals While operating in network, the master VT may signal, using Led X0, the existence of a communications error in the network. This Led lights up when there is no communication with the VT5MT20 keypads or with the PLC. If the master VT notes the absence of communication with the PLC Led X0 flashes. If communication resumes Led X0 goes off. If the master VT detects the absence of communication with the VT5MT20 keyboards, Led X0 flashes and continues to flash even if communication resumes. To extinguish Led X0: • Enter the status page with + . • Move onto asterisk signalling error with or . • Press . • Move onto asterisk signalling number of keypad where the error is with or . • Press + . • Exit from status page with + .

13.5 Connection cable for ESA-BUS2 network

For serial cable ESA-BUS1 and for serial cable ESA-BUS2: • It is essential to use a twisted serial cable with total shielding with a pair of

conductors of 0.22mm² and an characteristic impedance of 120 Ohms. • It is essential to use a shielded serial connector. • The resistors are placed solely at the physical extremes of the ESA-BUS network.

The 120 Ohm resistance’s are placed only at the physical extremes of the ESA-BUS network, salded in the connector housing.

• It is essential that the cable shield be soldered onto the metal cases of all the • connectors that are then connected to the VTs in the network.

14 field network

38 ESA elettronica

14 Field network

14.1 Profibus/DP The terminals that have the “VT5PROFI/DP” network card can be connected as “slaves” (passive stations that can only transmit data following a request made by an active station). The PLCs and the network configurator, on the other hand, are “masters” (active network stations that can transmit information without request). A network may contain more than one PLC but only one network configurator. .

14.1.1 VT5PROFI/DP card

Ex:Dip-Switch configuration

address 3 Set the switches with the number of the “slave” of the VT that has been configured with the network configuration SW. The maximum speed the VT5PROFI/DP card can work at is 12MBaud. The card automatically assumes the speed of the network which is in turn determined by the network master unit.

14.1.2 How the VT works in the net The “slaves” are seen as areas of memory “mapped” in the I/O area of the PLC, which is used for the data exchange between PLC and VT. Each I/O area is particular to a given VT and its size is defined by the user. Certain I/O area words can be allocated such that a cyclical priority channel for data exchange words containing the status of the F/Shift-F keys or commanding the switching on of the LEDs. The information exchanged by the “masters” (PLCs) and the “slaves” (VTs) is of 2 types: • Alarms, data exchange words and data (non-cyclical service), that use the non-

cyclical I/O area. • Data exchange words for F/Shift F-keys and LEDs (cyclical service) Note that with the larger dimensions of cyclical and non-cyclical I/O area there is a corresponding speeding up of network management, all of which, however, requires a greater availability of PLC memory.

14.1.3 Configuration SW Three types of SW play their part in configuring this network: • VT-EDS • FB • The network master configuration SW. The common parameters of these SWs must be identical.

14

ESA elettronica 39

The parameters that need to be set in the in the VT-EDS project of every panel connected to the network are: • Dimensions of I/O area, expressed in number of words; • Dimensions, in number of words, of the cyclical WRITE-areas for F-keys and

READ for LEDs; • Data exchange words containing the status of the F-keys and the commands

switching on the LEDs. • Cyclical timeout and non-cyclical timeout whose expiry could mean that there is a

block in the SW being executed in the PLC. FB is the program supplied by ESA to be loaded into the PLC and by means of which the user can check the network parameters set and the information exchange. It varies according to the type of PLC (make and model). This type of SW requires, besides the parameters for VT-EDS that we have already seen, from the outset further information specific to the PLC that will host the SW. This information in contained in detail in a text file included in the “VT-PROFIBUS Installation SW” disk. The configuration SW for the network master is supplied by the maker of the network master unit. A typical input mask for parameters relating to the VTs might look like the following: No.(1) Name Configuration(2) Setting(3) Length(3) 1 VT550 Input Area Input 8 2 xxxxxx Output Area Output (1) Make sure that the number of “slaves” is also set with the “dip switch” of the

network card contained in the VT. (2) Input area: the area in which the network card writes commands and data to be

sent to the PLC Output area: the area in which the network card reads the commands and data coming from the PLC. In the VT-EDS these 2 parameters are found in a single area (I/O area). (3) Make sure that the input and output areas have the same lengths defined that will be set in the VT-EDS in the “dimensions of I/O area” expressed as a number of words. If the configuration SW requires that the unit of measurement for this option is the byte, then the necessary conversions must be made.

15 ascon thermoregulators (driver on com0)

40 ESA elettronica

15 Ascon thermoregulators (Driver on COM0) VT500 can communicate simultaneously with a PLC and the 255 ASCON thermoregolators connected with one another in a network. Each thermoregulator must have its own address different from that of any other themoregulator present. Communication with the thermoregulator is over the serial port COM0 (RS232). During the creation of the project, you must declare the type of PLC you intend to connect with COM1,as well as the series of ASCON thermoregolators you intend to connect to COM0 using the appropriate translator. Once the project has been created, it must be transferred to the VT, updating where necessary the communications drivers on COM1 and on COM0. If in the VT the driver on COM0 is already present, then in order to enter into communication with thel PC you have to enter the service page using the keys: + . N.B.: to avoid malfunctioning of the VT,it is important that both the driver on COM1 and that on COM0, be transferred using exactly the same version of VT-EDS. Once the project has been transferred - and perhaps the two drivers - you must disconnect the VT-PC connecting cable and connect the VT-Thermoregulator cable to COM0. N.B.: if in the VT the driver on COM0 is active, it will not be possible to use this

port for connecting a serial printer.

The value to insert in S11 must be written by the PLC and it must be remembered that S11 (16 bits) is divided into 2 bytes, one( the HIGH BYTE ) determining the alarm word at the BEGINNING of the block, while the other (the LOW BYTE) determines the alarm word at the END of the block.

The values to introduce in the 2 bytes must be expressed in HEXADECIMAL format. In the present case the value to introduce in the high byte must be 3 decimal ( 3 hex ), while the low byte must have a value of 10 decimal ( A hex ). The hexadecimal value to introduce into S11 will therefore be 030A hex. With S11 set in this way, the VT500 will be able to display the alarm words from word 3 (PLC SIEMENS DB5 DW3) to word 10 (not used).

Exchange bits for data memory Variable S36 is a variable used to signal to the PLC that the VT is about to make a synchronized recipe transfer. This variable works strictly in combination with the variable S37. When you insert S36 in the WRITE data exchange, S37 need to be inserted in the READ data exchange. To understand how they work, let us follow the steps described below: Using synchronized transfer for peripheral 1. • VT raises bit 0 of S36 and waits for the PLC to confirm before starting to transfer

the recipe. • The PLC must raise bit 0 of S37, to confirm to the VT that it can start transferring

(Max. 2 sec.). • The VT sets bit 0 of variable S36 at 0. • The PLC sets bit 0 of S37 at 0. • The VT starts transferring the recipe. • When the transfer is over the VT raises bit 4 of S36 and waits for the PLC to

confirm the termination of the transmission by raising bit 1 of S37 (Max. 2 sec.). • The PLC sets bit 1 of S37 at 1. • The VT sets bit 4 of S36 at 0. • Transfer phase over.

Exchange data for Recipe Codes The variables from S42 to S49 contain the recipe code, in ASCII, that the PLC asks the VT to transfer to it. This code must be written by the PLC, using the number of characters used in the recipe code structure in the VT-EDS. Example: If a 4 character code has been declared for a recipe in the VT-EDS, the PLC must write that code in ASCII using all 4 characters and consequently the using variables S42 and S43. The other variables, those from S44 to S49, are ignored by the VT. Thus 2 characters for each S variable . Thus each variable is considered by the VT as if it were composed of 8 bits for the MOST SIGNIFICANT part and 8 bits for the LEAST SIGNIFICANT part. In the example below the PLC asks the VT for the recipe RIC1

18.9 Exchange data bits for recipes Variable S50 enables the PLC to order the sending of a recipe to the VT. The code for the recipe is found in the variables from S42 ÷ S49. Variable S51 enables the VT to communicate to the PLC the result of the transfer and any errors that might have occured.

CCFL display LAMP

IMPORTANT VT600 panels are equipped with a lamp giving backlit CCFL display. This lamp has a

limited life.The average life of these lamps depends on the temperature of the environment in which they work.The maker declares the following for a temperature of

25°:VT600 display STN 20000h.After this time the loss of luminosity may have reached 50% or even be total.The loss may be much quicker (from 20000h/25000h to 2000h) if the working temperature is close to 0° or above 40°.To increase the life of

the lamp, ESA has created a special bit that switches off the lamp via a PLC command. This feature is only advised for temperatures near the operational limits.

VT battery

The battery protects the content of RAM (work recipes) and powers the internal clock (12 microamps at a temperature of 25°C) in the absence of power supply. At the moment of purchase there is no battery in the VT, thus inserting it is a matter for the client.

Battery to be used: 3 1,5 Volt alkaline batteries

MN 1500, LR6, SIZE AA We recommend substituting the batteries every 12 months. • When the battery Led (situated on the VT keypad) lights up it means that the

battery should be substituted. The content of the data memory will be lost if the battery is not renewed. Apart from this, the VT communicates via the appropriate bit in the VT-PLC data exchange area that the batteries are flat.

• The the VT must be on when the batteries are changed !!! It is important to pay great attention not to touch accidentally the electronics of the terminal itself.

22 power supply

70 ESA elettronica

The state of the battery can be read from the “Battery“ led on the front of the VT

30 ESA-BUS network With the ESA-BUS network you can connect many VTs to a single PLC. The system is made up of one master VT connected to the PLC and to up to 31 slave VTs. To make the network function, the ESA-BUS board must be inserted in the VT that is to be used as master. The job of the master VT is to interact with the PLC on its own account and for the other VTs. Each VT connected in the network must have its own address, unique in that network; there must never be two or more VTs with the same address. The address of the master VT is always 0, the slaves can have addresses from 1 to 31. It is essential that the connected slaves have consecutive addresses, starting from 1 and running to the number of VTs in network (maximum of 31). The master VT carries out the data exchange starting with slave no. 1 and finishing with the last SLAVE declared (maximum 31).

Defining the master VT parameters Using the service page, input the address to be assigned to the master VT, that is 0, and the number of slave VTs (maximum 31). Operations necessary for inputting network parameters: • Enter service page using + . • Go to field "ADDRESS" using or . • Select the number "0" using or . • Go to field "MAX STATION" using or . • Select the number of slave VTs connected to the master using or . • Exit from service page by using or + .

30.2 Master VT error signals While operating in network, the master VT may signal, using Led X0, the existence of a communications error in the network. This Led lights up when there is no communication with the VT5MT20 keypads or with the PLC. If the master VT notes the absence of communication with the PLC Led X0 flashes. If communication resumes Led X0 goes off. If the master VT detects the absence of communication with the VT5MT20 keyboards, Led X0 flashes and continues to flash even if communication resumes. To extinguish Led X0: • Enter the status page with + . • Move onto asterisk signalling error with or . • Press . • Move onto asterisk signalling number of keypad where the error is with or . • Press + . • Exit from status page with + .

For serial cable ESA-BUS1 and for serial cable ESA-BUS2: • It is essential to use a twisted serial cable with total shielding with a pair of

conductors of 0.22mm² and an characteristic impedance of 120 Ohms. • It is essential to use a shielded serial connector. • The resistors are placed solely at the physical extremes of the ESA-BUS network.

The 120 Ohm resistance’s are placed only at the physical extremes of the ESA-BUS network, salded in the connector housing.

• It is essential that the cable shield be soldered onto the metal cases of all the • connectors that are then connected to the VTs in the network.

31 Ascon thermoregulators VT600 can communicate simultaneously with a PLC and the 255 ASCON thermoregolators connected with one another in a network. Each thermoregulator must have its own address different from that of any other themoregulator present. Communication with the thermoregulator is over the serial port COM (RS232). During the creation of the project, you must declare the type of PLC you intend to connect with COM1-4,as well as the series of ASCON thermoregolators you intend to connect to COM1-4 using the appropriate translator. Once the project has been created, it must be transferred to the VT, updating where necessary the communications drivers on COM1-4. N.B.: to avoid malfunctioning of the VT,it is important that both the driver on COM1-4, be transferred using exactly the same version of VT-EDS. Once the project has been transferred - and perhaps the two drivers - you must disconnect the VT-PC connecting cable and connect the VT-Thermoregulator cable to COM.

The value to insert in S14 must be written by the PLC and it must be remembered that S14 (16 bits) is divided into 2 bytes, one( the HIGH BYTE ) determining the alarm word at the BEGINNING of the block, while the other (the LOW BYTE) determines the alarm word at the END of the block.

DATA EXCHANGE WORD S14 LIMITS OF THE BLOCK OF ALARMS TO BE DISPLAYED

BIT 8 ÷ 15 (HIGH BYTE) BIT 0 ÷ 7 (LOW BYTE)

OFFSET 1ª ALARM WORD TO BE DISPLAYED

OFFSET LAST ALARM WORD TO BE

DISPLAYED

The values to introduce in the 2 bytes must be expressed in HEXADECIMAL format. In the present case the value to introduce in the high byte must be 3 decimal ( 3 hex ), while the low byte must have a value of 10 decimal ( A hex ). The hexadecimal value to introduce into S14 will therefore be 030A hex. With S14 set in this way, the VT600 will be able to display the alarm words from word 3 (PLC SIEMENS DB5 DW3) to word 10 (not used). Consequently all the alarm words of the PLC OMRON will be displayed, while the first 2 alarm words of the PLC SIEMENS (DB5 DW0 and DW1) will be ignored.

Exchange bits for inputs Variables S37 and S38 contain the status of the S keys of the VT600 only if these keys have been configured as inputs. In the case of VT601 the sole variable to be used is S37, in that this VT can use no more than 11 inputs. By status we mean the value acquired by the key in the PLC. This value may be either 1 or 0. As distinct from variables S20 and S21, these variables can contain several bits set at 1 at the same time. Indeed, if the S keys are configured as inputs and to work in REAL TIME mode, by pressing several S keys at the same time, the corresponding bits will be set at 1. Example 1: • Let us imagine that we want to configure the S keys as inputs and to work in FLIP

FLOP mode. • Let us suppose that in the PLC the word has been set at 1. By pressing an S key the VT will set the corresponding bit at 0. Example 2: • Let us imagine that we want to configure the S keys as inputs and to work in REAL

Variables S39 and S40 are used whenever you want to change the configuration of the S keys of the VT600, which have been configured as inputs, independently of the setting effected by VT-EDS. S keys can operate in REAL TIME or in FLIP-FLOP mode. When the key-related bit is set at 0, the corresponding S key will operate in REAL TIME mode; alternatively, when the bit is set at 1 the S key will function in FLIP-FLOP mode. When these variables are put in the data exchange area, the VT will use the appropriate bits to configure the S keys, ignoring the settings made through the VT-EDS. Thus if you intend using the settings made with VT-EDS, it is not necessary to insert these variables in the data exchange area of VT600. These variables are introduced in the READ area.

Exchange bits for inputs leds The variables from S41 to S44 determine whether the LED should be controlled internally or with the PLC. These variables can only be used if the S keys have been configured as inputs. If the status of the bit related to the key is at 0 (zero) it means that only the PLC controls the led of that key; otherwise (status of bit at 1) the control of the led of that key is both VT and via the PLC. If you enable the data exchange containing these variables the settings effected by VT-EDS will no longer be valid. It is those set by the PLC that will be valid. With the bit status at 1 (controlled both internally), priority goes to control by the PLC in the event of a conflict (if you try to switch on the same led using both internal and PLC control).

The variables from S45 alla S52 determine the coming on or going off of the LEDs as well as their mode of operation. These variables can only be used if yu have opted for internal control of the LEDs Using these variables the PLC can change the behaviour of the internal control of the leds of S keys configured as inputs, independently of the setting executed via the menu CONFIGURE LED S KEYS (see previous page). If these variables are not introduced into the data exchange, the settings made with the menu mentioned above will be right. If, on the other hand, you want to use these variables, the internal control of the S key leds will be subordinated to the status of the bits of these variables (1 bit for each S key led), i.e. the VT-EDS settings will no longer be valid; instead only the corresponding values present in the PLC will be used. If you use VT-EDS to set the RED and GREEN LEDs related to S key1 such that they are INTERNALLY controlled (by pressing that key , which has been configured as an input), then both the RED LED and the GREEN LED will come on automatically without the PLC doing any forcing. If variables S45 ÷ S52 are introduced into the data exchange of the VT600, the RED and GREEN leds of key S1 light up only if the bits of these variables associated to them are set at status 1, that is: BIT 1 of S45 at status 1 = RED led of key S1 switched on internally in FIXED mode. BIT 1 of S47 at status 1 = RED led of key S1 switched on internally in BLINKING mode. BIT 1 of S49 at status 1 = GREEN led of key S1 switched on internally in FIXED mode. BIT 1 of S51 at status 1 = GREEN led of key S1 switched on internally in BLINKING mode.

35.8 Data exchange bits for the data memory Variable S53 is a variable used to signal to the PLC that the VT is about to make a synchronized recipe transfer. This variable works strictly in combination with the variables from S54 to S57. When you insert S53 in the WRITE data exchange, one or more variables between S54 and S57 need to be inserted in the READ data exchange -how many will depend on the number of PLCs the VT600 is connected to. Otherwise no transfer will be possible. Each variable relates to a given peripheral, i.e.: • Variable S54 peripheral 1. • Variable S55 peripheral 2. • Variable S56 peripheral 3. • Variable S57 peripheral 4. These variables operate, as already explained, in a strictly linked way. To understand how they work, let us follow the steps described below: Using synchronized transfer for peripheral 1. • VT raises bit 0 of S53 and waits for the PLC to confirm before starting to transfer

the recipe. • The PLC must raise bit 0 of S54, to confirm to the VT that it can start transferring

(Max. 2 sec.). • The VT sets bit 0 of variable S53at 0. • The PLC sets bit 0 of S54 at 0. • The VT starts transferring the recipe. • When the transfer is over the VT raises bit 4 of S53 and waits for the PLC to

confirm the termination of the transmission by raising bit 1 of S54 (Max. 2 sec.). • The PLC sets bit 1 of S54 at 1. • The VT sets bit 4 of S53 at 0. • Transfer phase over. The steps described above are valid for each of the four peripherals not just one, only that, with the additional peripherals, different bits are used in place of S53, and different READ variables for S54, depending on the peripheral used.

35.9 Exchange data for Recipe Codes The variables from S65 to S72 contain the recipe code, in ASCII, that the PLC asks the VT to transfer to it. This code must be written by the PLC, using the number of characters used in the recipe code structure in the VT-EDS. Example: If a 4 character code has been declared for a recipe in the VT-EDS, the PLC must write that code in ASCII using all 4 characters and consequently the using variables S65 and S66. The other variables, those from S67 to S72, are ignored by the VT. Thus 2 characters for each S variable . Thus each variable is considered by the VT as if it were composed of 8 bits for the MOST SIGNIFICANT part and 8 bits for the LEAST SIGNIFICANT part. In the example below the PLC asks the VT for the recipe RIC1
