NOTE

In order to carry configuration out via the configuration plug (direct configuration), you require a direct configuration cable (order code "DPC"), the LeoPC 1 program (supplied with the cable) and the corresponding configuration files. Please consult the online help installed when the program is installed for a description of the LeoPC 1 PC program and its setup.


2 Description of functions

2.1 Control inputs

NOTE

The subsequent input "Blocking of watchdog functions / remote acknowledgment" does not exist in version 690 V.

Blocking protective device Remote acknowledgement Terminal 5/6

Due to a non-reset high-signal at the discrete input the release of various protection devices may be blocked. This may be useful for instance if the device is used as a generator protection device. Thus, tripping can be avoided for messages ( such as undervoltage or underfrequency) which are permanently active during a machine standstill. If blocking is not required, the discrete input should be permanently inter-connected with zero potential. The following functions can not be blocked with this discrete input : • Overvoltage • Overfrequency • Zero voltage • Ground fault monitor

External acknowledgement of the

relays via the discrete input "Blocking of watchdog functions / remote ac-

knowledgment".

External Clearing OFF

If you don't want the device to reset the relays automatically as soon as the alarm is no longer present, you must first set the function "Auto-clearing relay" to "OFF" (see chapter 4.5.1 "Auto-clearing relay" on page 39).

OFF ..........Alarms which cannot be blocked are no longer reset automatically if the tripping alarm is no longer present. Press the button "Clear" to re-set the relays.

ON ............All alarms which are present are reset if a rising edge is detected at the blocking input. (The discrete input "Blocking of watchdog functions / remote acknowledgment" must be reset from "0" to "1".) Alarms which cannot be blocked are only reset if the alarm is no longer pre-sent.


alarm messages via the discrete input "Blocking protective device / remote acknowledgement".


If you want the device to automatically reset the relays as soon as the alarm is no longer present, but not delete the messages on the display, you must first set the functions "Auto-clearing relay" to "ON" and "Auto-clearing message" to "OFF" (see chapter 4.5.1 "Auto-clearing relay" on page 39).

OFF ..........To reset the messages on the display, press the button "Clear". ON ............All display messages which are present are reset if a rising edge is

detected at the blocking input. (The discrete input "Blocking of watch-dog functions / remote acknowledgment" must be set from "0" to "1" .) Alarms which cannot be blocked are only reset if the alarm is no longer present.


2.2 Control outputs

NOTE

Please heed to the description of the relay manager in chapter 4.5.3 "Change relay assignment (relay manager; standard and option R)" from page 41.

Relay 2 Terminal 11-13

Output relay (version: Change-over contact) This relay is managed by the "relay manager" .

Relay 3 Terminal 14-16

Output relay (version: Change-over contact) This relay is managed by the "relay manager". If the option Yc is available, the mes-sage "networks are synchronous" is displayed.

Option R relay 47 Terminal 19-30

Output relay (version: Change-over contact) - Only if the option R is available. These relays are controlled by the relay manager.

Option R Relay 8 Terminal 31/32

Output relay (version: make contact) - only, if option R is available. This relay is managed by the "relay manager" . If Option R is available in addition to option Yc, the message "networks are synchronous" is displayed. The relay 3 is also managed by the relay manager.

2.3.2 Acknowledge alarms

An alarm is signaled with the LED "Alarm". Press the button "Clear" to acknowledge the alarms which are present. The following differences are made: The alarm ... ... is still present ................As long as the alarm is still present, it cannot be ac-

knowledged. This is signaled by the blinking LED "Alarm" on the front side.

... is no longer present ......As soon as the alarm has been eliminated, the blinking

light of the LED "Alarm" becomes a steady light. If the mask "auto acknowledge messages" is set to "ON", the LED is extinguished after the resetting time. If the mask "auto acknowledge messages" is set to "OFF", the LED is only extinguished after the button "Clear" is pressed.


3 Display and operating components

3.1 Front foil

The pressure-sensitive membrane of the front panel consists of a plastic coating. All keys have been designed as touch-sensitive membrane switch elements. The display is a LC display, consisting of 2 × 16 characters, with indirect green illumination.

4.1.2 Password (from Version 2.0xx / 3.0xx)

The device is equipped with a three-step code and configuration hierarchy which al-lows to make different configuration masks visible for different users. The difference is made between:

Code level 0 User: External person (CS0) This code level does not allow any access to the parameters. The enter function is

blocked.

Code level 1 User: Client (CS1) This code level authorizes the user to modify a few pre-selected parameters. The

password cannot be changed at this level.

Code level 2 User: Commissioning engineer (CS2) With this code level 2 the user obtains all access rights, thus having direct access to

all parameters (viewing and changing) Moreover, at this level, the user is also author-ized to establish passwords for levels 1 and 2.

NOTE

Once the code level is set, it will not be changed even after entering the configuration repeatedly. If entering an incorrect code number, the code level is set to CS0, thus locking the device for external persons (Entering of the passwords on page 23). Two hours after the last operator action, the device automatically switches to the code level CS0. By entering the appropriate code number you go back to the corresponding level.

Enter code number XXXX

Enter code number 0..9.999

When entering the configuration mode, a code number to identify the different users is inquired first. The number XXXX, which is indicated is a random number and is confirmed with the button "Select". If the random number is confirmed with "Select" without changing it, the code level of the device is not changed. In order to change the code level and to install new passwords for the users, there are two four-digit code numbers(0000..9999). For the user level "External person" no assignment is necessary, since normally, the user does not obtain the right to access the configu-ration level (protected by the codes).


4.1.3 Change passwords (from v 2.0xx/3.0xx)

NOTE

Once the code level is set, it will not be changed even after entering the configuration repeatedly an incorrect code number has been entered, the code level is set to CS0, thus locking the device for external persons. If for 2 hours uninterruptedly supply voltage is applied, the device automatically switches to code level 0.

Define level 1 code 0000

Code level 1 (client) 0..9.999

This masks appears only from code level 2. After entering the digits into this mask, the code level for level 1 (client) is set. After entering the code, the client only has the access rights assigned to him. This code level (CS) is preset to CS1 = 0 0 1

Define level 2 code 0000

Code level 2 (commissioning engineer) 0..9.999

This masks only appears from code level 2. After entering the digits into this mask, the code level for level 2 (technician) is set. After entering the code, the technician has the access rights with which he was assigned. This code level (CS) is preset to CS2 = 0 0 0 2

4.2.5 Configuration of the Type of Monitoring

NOTE

This configuration mask does not appear if a "Three-wire installation"-voltage measuring has been selected in the configuration mask "voltage measuring" see chapter 4.2.2 "Voltage Measuring" on page 25.

Mask for "phase-neutral":

Volt.-Monitoring phase-neutral

Mask for "phase to phase":

Volt.-Monitoring phase-phase

Monitoring Phase to phase/phase-neutral

The device may monitor either the phase voltages (four wire installation) or the lline-to-line voltages (three-wire installation). Usually, when using alow-voltage system (400/690 V-version) the phase voltages are monitored (mask text: v(phase-N)), and line-to-line voltages are monitored when using a medium-high-voltage system (100 V-Version) (mask text: v(ph-ph)). Monitoring of the line-to-line voltage is par-ticularly necessary to avoid the tripping of the voltage relays by a line-to-ground fault in an isolated-neutral or compensated system. The mask "voltage measuring" has no effect on this mask but the one described under . The settings in the mask ".Volt. Monitoring" do have the following effect on the configuration masks: Phase-neutral ............ The voltages at the terminals 1 to 4 are measured as if for a

phase-neutral installation and the voltage monitoring of all subsequent masks are referred to the phase-to-zero voltage (UL-N). In the configuration masks, this is indicated by adding "(phase-N)".

Phase to phase.......... If the voltage system connected to the terminals 1 to 4 is a phase to phase installation, this setting must be selected. The measurement and all subsequent masks referring to voltage monitoring are related to the wire-to-wire voltage (UL-

L). In the configuration masks, this is indicated by adding "v(ph-ph)".


4.3 Configuration of control functions

4.3.1 Control function for the synchronization (option Yc)

NOTE

This option Yc cannot be used for 690 V-devices; please refer to chapter 1.3.2b.) "Synchronizing voltage (option Yc - option Iv not available) on page 8.

a.) Output of the signal "voltages are synchronous"

Considering various criteria, an add-on order is output by the device to a power cir-cuit breaker which is designed to connect two sub networks after adjusting the re-spective voltages and frequencies. The add-on order has a predefined minimum turn-on time and is output to a relay. The relay output is firmly assigned to relay 3 (for de-vices without option R) or to relay 8 (for devices with option R).

Function "Synchronization with differential frequency" The electrical phase lead for the output of the add-on order is calculated for each de-vice in a way to always keep the lead time constant, regardless of the current differ-ential frequency. If both, differential voltage and differential frequency, fall below the values adjusted between the two voltage systems, the add-on order can be output, considering the following conditions: • The current r.m.s. voltages of both networks must be more than 75 % each, and

less than 112.5 % of the adjusted rated voltage. • The voltage must fall below the maximum admissible differential voltage adjusted

between the two networks. • The frequency must fall below the maximum adjusted differential frequency be-

tween the two networks. • The electrical angle between two cophasal phases must be smaller than the corre-

sponding maximum admissible error angle (depending on the slip, max. 8 °el.).

b.) Synchronous networks

For synchronous networks, an add-on order is also output by the device as long as the electrical angle between the systems is less than +/-2 °el. and the voltage falls below the voltage difference adjusted.

OFF ..........There is no monitoring, and the subsequent masks of this function are not indicated.

Synchronization df max. 0,18Hz

Max. admissible differential frequency for synchronization 0.02..0.49 Hz

A required condition for the output of an add-on order is that the frequency falls be-low the adjusted differential frequency. This value is valid for a positive slip. Positive slip means: Generator frequency greater than mains frequency (synchroni-zation voltage).


Synchronization df min. -0,10Hz

Min. admissible differential frequency for synchronization 0.00..-0.49 Hz

A required condition for the output of an add-on order is that the frequency falls be-low the adjusted differential frequency. This value is valid for a negative slip. Nega-tive slip means: Generator frequency less than mains frequency (synchronization voltage).

Synchronization dU max = 00,0%

Max. admissible differential voltage 0.1 .. 15.0 %

The percentage indication refers to the secondary voltage adjusted. A required con-dition for the output of an add-on order is that the voltage falls below the adjusted differential voltage.

Synchronization Time pulse>200ms

Min. pules time of the add-on relay 50..250 ms

The duration of the add-on pulse can be adjusted to the subsequent switch unit. The minimum time required for the output of the add-on order is adjusted here.

The value of the underfrequency (level 2), to be monitored is adjusted in this mask. If the value is reached or falls below the value adjusted, the device outputs an alarm message. If additionally, a relay has been programmed with the relay manager, an-other output is made to this relay.

Underfrequency 2 Delay 00,00s


For a tripping, the frequency must fall below the threshold for at least as long as in-dicated in this mask.

Underfrequency Hysteres. 0,00Hz

Hysteresis for the underfrequency monitoring, levels 1+2 0.01..9.99 Hz

In order to avoid that the signal relay keeps picking up and releasing when ap-proaching the adjusted threshold for the underfrequency (both levels), it is possible to indicate an absolute value for the difference between the threshold and release value (hysteresis), referring to the threshold.


4.4.7 Phase/vector shift monitoring (option V)

A phase/vector shift is defined as the sudden variation of the voltage curve which may be caused by a major load change of a generator. In this case, a one-time varia-tion of the cycle duration is detected by the measuring circuit. This modified cycle du-ration is compared with a calculated mean value from earlier measurements. The monitoring is three-phased. The threshold in degrees indicates the time difference between mean value and instantaneous value, referring to a full period. The monitor-ing can be set in different ways. The phase/vector shift monitor may used as an addi-tional equipment for the mains decoupling. The minimum voltage to activate the phase/vector shift is 70 % of the nominal secondary voltage.

Function "Cycle duration of the voltage not within the admissible range" The cycle duration of the voltage is not within the adjusted limiting value for the phase/vector shift. An alarm message is displayed. This message can be suppressed with the discrete input "Blocking of watchdog functions / remote acknowledgment".

Phase shift monitoring ON

Phase/vector shift monitoring ON/OFF

ON ............The voltage/frequency is monitored, and a phase/vector shift is regis-tered within the defined range. The subsequent masks of this function are indicated.


Phase shift mon. one/three phase

Phase/vector shift monitoring single-/three-phase..only three-phase

single-/three-phase ... When single-phase voltage monitoring is used for a phase/vector shift, tripping is released if at least one of the three phases exceeds the adjusted threshold. This kind of monitoring is very sensitive and may lead to false tripping if the selected phase angle is too small.

three-phase only ..When three-phase voltage monitoring is used for a phase/vector shift, tripping is only released if the phase/vector shift exceeds the adjusted threshold within 2 periods.

NOTE

If monitoring is set to "three-phase only", only the bottom mask of the two subsequent mask is visible; if monitoring is set to "single-/three-phase", both parameter masks are visible.

Phase-jump value (One phase) 00°

The mask is only visible, if monitoring is set to "sin-

gle/three-phase" .

Phase angle phase/vector shift monitoring, single-phase 2..90 °

Tripping is released if the electrical angle shift of the voltage curve in a phase ex-ceeds the adjusted angle. If the value is reached or exceeded, the device outputs an alarm message. If additionally, a relay has been configured with the relay manager, another output is made to this relay.

Phase-jump value (3-phase) 00°

Phase angle phase/vector shift monitoring, three-phase 3..90 °

Tripping is released if the electrical angle shift of the voltage curve exceeds the value of the adjusted angle in all three phases simultaneously. If the value is reached or exceeded, the device outputs an alarm message. If additionally a relay has been configured with the relay manager, another output is made to this relay.


4.4.8 df/dt monitoring (option D)

Function "Frequency change per unit time of the voltage not within the admissible range" The device calculates a measuring value for the frequency change per unit time. In order to guarantee a reliable differentiation between phase/vector shift and df/dt, measurements made during 4 periods. The result is a minimum tripping time of ap-prox. 100 ms (at 50 Hz). This message can be suppressed with the discrete input "Blocking of watchdog functions / remote acknowledgment".

df/dt Delay T= 0,0s

Pickup delay 0.1..9.9 s

For a tripping, the threshold must be exceeded for at least as long as indicated in the mask.

4.4.9 Non-directional ground fault monitoring (option Iv)

The device may be used for the logging of ground faults in the stator winding of three phase machines feeding the mains via a unit connected transformer. In case of an ground fault, the occurrence of displacement voltage is primarily used to release a tripping, thus reaching a protection range of up to approx. 95 % of the winding.

a.) First tripping level for the displacement voltage

Function Measurement of the displacement voltage The displacement voltage is usually measured by the open delta winding (e-n-winding) of a voltage transducer or by the zero point transformer in the machine star point. If transformers are used which supply voltages greater than 100 V during terminal ground fault (e. g. 240 V, 500 V), voltage has to be reduced externally to a level of 0..100 V, using a voltage divider. The single-phase contents of the third har-monic which occurs particularly when synchronous machines are used, are added by summation, so that an interference-free measurement is only guaranteed if a highly effective filter method is used. An alarm message is displayed. This message can be operated with the relay manager, but cannot be suppressed with the discrete input "Blocking of watchdog functions / remote acknowledgement".


Earth fault Ue monitoring ON

Non-directional ground fault monitor ON/OFF

ON ............The non-directional line-to-ground fault is monitored, and the subsequent masks of this function are indicated.


Earth fault Ue> Release 000V

Threshold displacement voltage, level 1 3..100 %

If the adjusted threshold is exceeded after the pre-set time lag, a tripping is released. If additionally, a relay has been configured with the relay manager, another output is made to this relay. The threshold in percent is referred to the nominal displacement voltage (normally 100 V).

Earth fault Ue> Delay 00,00s

Time lag displacement voltage, level 1 0.02..99.98 s


b.) Second tripping level for the displacement voltage

Function "line-to-ground fault Ue>> for switching loading device" For insulated or compensated networks loading devices may be used to increase the earth current. The performance of these devices is usually not designed for continu-ous load with full displacement. Therefore these devices have to be switched off as soon as the displacement voltage exceeds a critical value. Please note however that the loading device may only be switched off after the tripping of the ground fault monitor. The reaction of the second level must therefore be slower if user to switch off a loading device. Moreover, the threshold must exceed the thresh-old of the first level. An alarm message is displayed. This message can be operated with the relay manager, however cannot be suppressed with discrete input "Blocking of watchdog functions / remote acknowledgment".

Earth fault Ue>> Release 00V

Threshold residual voltage, level 2 3..100 %

Exceeding of the adjusted threshold after the adjusted time lag releases the tripping. If additionally, a relay has been configured with the relay manager, another output is made to this relay. The percentage value of the threshold is referred to the nominal-displacement voltage (normally 100 V).

Earth fault Ue>> Delay 00,00s

Time lag residual voltage, level 2 0.02..99.98 s

For a tripping, the value of threshold must be exceeded continuously for at least as long as indicated in this mask.


4.5 Configuration of the relay

NOTE

Operating current (NO) The relay picks up during the tripping, i. e. current flows through the coil while in operate condition.

In case of a loss of the supply voltage the state of the relay remains un-changed and no tripping is released. In this case the readiness for opera-tion of the device should be monitored.

Closed-circuit current (NC) The relay drops out during the tripping, i. e. current flows through the coil

while in release condition. The relay picks up while in release condition (= no tripping).

In case of a loss of the supply voltage the state of the relay is changed and a tripping is released.

Blocking protective device Remote acknowledgement Terminal 5/6

Due to a non-reset high-signal at the discrete input the release of various protection devices may be blocked. This may be useful for instance if the device is used as a generator protection device. Thus, tripping can be avoided for messages ( such as undervoltage or underfrequency) which are permanently active during a machine standstill. If blocking is not required, the discrete input should be permanently inter-connected with zero potential. The following functions can not be blocked with this discrete input : • Overvoltage • Overfrequency • Zero voltage • Ground fault monitor


NOTE

The subsequent function "External clearing" has various consequences, depending on the setting of the configuration masks "Auto-clearing relays" and "Auto-clearing display". Below please find the corresponding explanations.



relays via the discrete input "Blocking of watchdog functions /

remote acknowledgment".

Acknowledgement via the discrete input ON/OFF

If the device should not automatically reset the relays as soon as the alarm is no longer present, it is necessary to first set the function "Auto-clearing relays" to "OFF" (see chapter 4.5.1 "Auto-clearing relay" on page 39).

OFF ..........Alarms which cannot be blocked are no longer automatically reset, if the releasing alarm is no longer present. The relays are reset by pressing the button "Clear".

ON ............All active alarms are reset if a rising edge is detected at the blocking in-put. (The discrete input "Blocking of watchdog functions / remote ac-knowledgment" must be set from "0" to "1".) Alarms which cannot be blocked are only reset if the alarm is no longer present.


External acknowledgement of the alarm messages via the discrete input "Blocking protective device

Acknowledgement via the discrete input ON/OFF

If the device should automatically reset the relays as soon as the alarm is no longer present however leave the messages on the display unchanged, it is necessary to first set the functions "Auto-clearing relays" to "ON" and "Auto-clearing display" to "OFF" (see chapter 4.5.1 "Auto-clearing relay" on page 39).

OFF ..........The display messages are reset by pressing the button "Clear". ON ............All active display messages are reset if a rising edge is detected at the

blocking input. (The discrete input "Blocking of watchdog functions / re-mote acknowledgment" must be set from "0" to "1" .) Alarms which can-not be blocked are only reset if the alarm is no longer active.

indicated. NO ............The relay assignment remains unchanged and the subsequent masks

are not indicated.

Example Relay 1..3

NOTE

The outputs are configured in the same way for all relays. Exemplary configuration is shown here for the relays 1 to 3. With option R, it is possible to use another 5 relays. The relay 1 is always linked with the message "Readiness for operation".

Funct. relay 123 (R=releases) RRR

Function of the relays 1, 2 and 3 A/R

By selecting operating current or closed-circuit contact the various control principles are differentiated. It is possible to use an operating current output if a wire break cannot lead to a major alarm; the closed circuit output fulfills further tasks, e.g. for conductors relevant for safety. The relay 1 is permanently configured for R (closed-circuit current) and cannot be modified. For the description of the difference between operating current and closed circuit output please refer to chapter 4.5 "Configuration of the relay" on page 38.


NOTE

The subsequent masks are only visible if the corresponding protective device is switched on. If monitoring is set to "OFF", the mask does not appear. Neither are the subsequent masks visible if the configuration masks "Change relay allocation" is set to "OFF". Of course, these masks are not visible if the corresponding option is not included in the device.

6.1.1 Description of the data format

NOTE

The value is calculated from the measured value and the exponent!

Voltage 0..9.999 without sign measured in [V]

Frequency measured in [Hz × 100]

a.) Example

UG12 = 103, Exponent = 2 103 ⋅ 102 [V] = 1.030 [V] = 10.3 kV fGN = 5230 5.230 [Hz ⋅ 100] = 52,30 [Hz] = 52.3 Hz

b.) Bit change at tripping of a protective device

If one of the protective devices has responded, the corresponding bits are changed (-example: Bit 15/14 = overfrequency level 2) from not tripped (= 0/1) to tripped (= 1/0).


6.1.2 Frame date for the interfaces

a.) Frame data for the procedure 3964 (TTY, RS232, RS485)

Data Length of characters...... 8 Bit Stop bit .......................... 1 Bit Parity bit ........................ 1 Bit with even parity Release condition .......... Corresponds to the status log. "1" (20 mA bei TTY) Data format ................... 16 Bit binary values Transmitting rate ........... 9.600 Baud. Other baud rates on request. The records are

transferred cyclically. Flow Interpreter RK 512 see Siemens documentation for procedure 3964.

b.) Frame data for hardware handshaking RTS/CTS (RS232, RS422)

Data Length of characters 8 Bit Stop bit .......................... 1 Bit Parity bit ........................ 1 Bit with even parity Data format ................... 16 Bit binary values Transmitting rate ........... 9.600 Baud. Other baud rates on request. The records are

transferred cyclically.

Procedure If the transmitter is ready for data transmission, it signals this to the receiver by put-ting its control wire RTS in the "ON"-status. The prerequisite of this is that no data are received (CTS = "OFF"). The receiver registers this status and signals its readiness for reception by the "ON"-status of its RTS-wire. The transmitter can then begin transmitting when it detects this "ON" status on its CTS line. As soon as the receiver withdraws its RTS signal (RTS = "OFF"), the transmitter interrupts its transmission and waits until the receiver is ready to receive again. Both, the initialization conflict (both subscribers setting the RTS wire simultaneously) and the Time-Out (one sub-scriber waiting in vain for response), have to be considered.

c.) Frame data for the MOD bus RTU slave

Parameter Transmission protocol ................................................................. MOD bus RTU slave Hardware............................................................................................ interface RS485 transmitting rate............................................................................................adjustable Slave address...............................................................................................adjustable Parity ............................................................................................................adjustable With one order, a maximum of 10 words can be read or. 4 words can be written . MOD-bus function codes 03, 04, 06 and 16 are supported.


d.) Frame data for the CAN bus

Parameter transmission protocol................................................................................... CAN (CiA) Hardware....................................................................................................... CAN-Bus transmitting rate............................................................................................adjustable particularity......................................................................................Bt0 = 03, Bt1 = 1C Every 200 ms a data telegram of 8 bytes is cyclically transmitted, which is configured as follows (all word formats are high Byte / low Byte):

Transmitting data ID .......................Basic-ID transmission + CAN-number Byte 1 .................Multiplexor [1..9] Byte 2 .................always 221 Byte 3/4 ..............1. data word (see table no. 1), multiplexed (MUX = 1, 1) Byte 5/6 ..............2. data word (see table no. 2), multiplexed (MUX = 1, 2) Byte 7/8 ..............3. data word (see table no. 3), multiplexed (MUX = 1, 3) Byte 9/10 ............4. data word (see table no. 4), multiplexed (MUX = 2, 1) Byte 11/12 ..........5. data word (see table no. 5), multiplexed (MUX = 2, 2) etc.

Control data Option Sb ID .......................Basic-ID control + CAN-number A data telegram of 7 Bytes is expected, which is configured as follows (all word for-mats in high Byte / low Byte): Byte 1 .................Multiplexor Byte 2/3 ..............1. data word (see table no. 1), multiplexed (MUX = 1, 1) Byte 4/5 ..............2. data word (see table no. 2), multiplexed (MUX = 1, 2) Byte 6/7 ..............3. data word (see table no. 3), multiplexed (MUX = 1, 3) etc.

Configuration data Option Sf ID ....................... ID configuration (standard value: 831)

General IDs must not be assigned twice within the system. This applies to all devices linked to the bus system. Also, all IDs adjusted at the device must have different values. Procedure for basic-ID-transmission All devices available for the bus system are assigned the same "Basic-ID Transmis-sion". This way, the information types are grouped. Example: The same basis–ID transmission = 800 is set.

Due to the different device numbers, the individual IDs can be assigned. Device number 1: ID = 801 Device number 2: ID = 802 etc. Procedure for basis-ID-control The same procedure applies to the basis-ID control. (Standard value 224)


e.) Frame data for Profibus DP

Reception range Byte 0 and following ................................................Telegram according to description Example: No. 1 - Byte 0/1 = telegram call sign "302"

No. 2 - Byte 2/3 = voltage L12 No. 3 - Byte 4/5 = voltage L23 No. 4 - Byte 6/7 = voltage L31 etc. Byte 185 ....... The bit 0 becomes unstable every 2.5 seconds. This may be used as a

control to check if the interface is still working properly.
