1 Introduction

1.1 Short Description

With the IBS S5 SL LB communication interface board, the INTERBUS systemcan directly transfer data from a host computer to a subordinate control systemor vice versa. For this purpose the commmunication interface includes up to 16bidirectional registers. In case of a system failure or bus malfunctions the masteror slave system can respond to the error.

The user determines the behavior of the communication interface board. To this effect there are seven switches (S2, switch field: S1.3 through S1.8; Figure 1-1) and seven jumpers (X3-X5, X7-X11; Figure 1-1). The switch and jumper func-tions will be explained in the following sections.

1.1.1 IBS S5 SL LB Communication Interface Board

The IBS S5/SL-LB communication interface board is an element of the local busand behaves essentially like a module with digital inputs and outputs.The advantage is that defined groups can be disabled; i.e. a local bus branchcan be disabled while the rest of the INTERBUS system remains active.The user determines the behavior of the IBS I/O communication interface board.To this effect a switch field (S1.3 through S 1-8; Figure 1-1) is provided, whichis used to configure the following:

- Setting of the base address- Locations of the registers in the Q or P area of the PLC.

Jumpers X3 and X4 (Figure 1-1) can be used to respond to slave and mastersystem errors.In addition, there are also the jumpers X5, X7, X8, X9, X10 and X11 which willbe explained further below.

The switch functions will be explained in Section 2, the jumper functions in Section 5.

1.2 Defintions

The IBS S5 SL LB board is operated in an INTERBUS system. The board hasthe identification no. 171 (hex: AB). The INTERBUS controller board controls thedata transfer from or to the communication interface board. For this reason twosystems have to be distinguished in the following: - the master system (with the INTERBUS controller board) and - the slave system (with the communication interface board).

For this INTERBUS configuration, the master does not have to be of the sametype as the slave system. All control systems and computers for which there areINTERBUS controller boards can be used as a master system:

In order to look at things in the same way the following will be agreed upon.The definition of the data direction uses the master system as the point of refer-ence.This means:

- OUT data is written by the master system to the IBS I/O communication inter-face registers,

- IN data is transferred by the slave system to the master.

In programming terms, the term "address" refers to a byte-by-byte access. Ofcourse, the PLC programmer can also access the communication register byteson a bit-by-bit basis.

The term "communication register" is not equivalent to the same term used inthe host controller board manuals. The latter refers to reserved register locationsbelow the settable windows in the P and Q areas. The term used in this manual only refers to the settable I/O area of the commmu-nication interface board.

2.1 Switch Meanings and Settings

2.1.1 Number of Communication Registers

16 bidirectional, one-byte (eight-bit) communication registers (COM_REG_0 to COM_REG_15) are the heart of a communication interface board. The user can make full use of these registers.To offload both the slave system and the master system from invalid data, the user can limit the length of the communication in-terface board to eight bidirectional registers. The number of registers can be changed with S2 (Figure 1-1, 8 W (=words) = 16 bytes; 4 W (=words) = 8 bytes).

2.1.2 Communication Register Addressing

The switch setting of S1.3 determines whether the communication registers ofthe board appear in the P and Q area of the Siemens slave system. (Figure 2-1)The slave system addresses the communication registers to be set via theswitches S1.3 through S1.8 (Figure 2-1). The start address is the lowest addressat which the slave system writes to a communication register, or from which itreads. The start address is obtained by adding up the values that are assignedto the switches S1.4 through S1.8 (see Table 2-1). However, only the values ofthe switches in "ON" position are added up. Depending on the set length (withS2), seven or 15 further address above the start address are additionally occu-pied for the communication registers.

Table 2-1: Significance of the address switches

Figure 2-2 shows the switch settings in two examples:- Example 1 is true for 16 communication registers in the P area of the slave PLCoccupying the addresses 176 to 191;

- For the second example the communication interface board is operated witheight communication registers in the Q area of the slave system occupyingregister addresses from 56 to 63.

Since the communication interface board occupies a minimum of eight bytes in the address area of the slave system, the address lines A0 through A2 (with the associated values 20 = 1, 21 = 2 and 22 = 4) are always directly evaluated on the board. If the board is operated with 16 communication registers, A3 (with the val-ue 23 = 8) is also directly evaluated on the board.

This has two important consequences for the user:- If the board is operated with eight communication registers, the user can only choose a start address that can be divided by eight. Starting from the set ad-dress, the comunication board also occupies the following seven addresses.

- If the board is operated with 16 communication registers, the user can only choose a start address that can be divided by 16. Starting from the set address, the communication board also occupies the following 15 addresses.

Switch Value Comment

S1.8 23 = 8 This value is only considered when the start address is calcu-lated and the communication board is operated with a length of eight bidirectional registers. If the board is operated with 16 communication registers, this switch must be in the "OFF" po-sition.

S1.7 24 = 16

S1.6 25 = 32

S1.5 26 = 64

S1.4 27 = 128

S1.3 This switch determines whether the communication registers of the board appear in the P or Q area of the Siemens slave system.

3 Addressing Within the INTERBUS Master System

The addressing within the INTERBUS master system depends on the host con-troller board used. The addressing differs slightly between the various possiblemaster systems. For detailed information on the addressing refer to the user ma-nuals for the different host controller boards. At this point a configuration example (Figure 3-1) is used to show in principle theaddress locations for the communication registers in the INTERBUS addressarea of the master system.The number of communication registers is set with S2 (Figure 1-1; see also Section. 2, "Adressing Within the Slave System").

With logical addressing, the INTERBUS system allows the user to assign thesame address to IN and OUT data communication registers within the mastersystem. When logical addressing is used, the address of each module can be freely sel-ected within the used address window (in the master). Note that the communi-cation interface board requires 8 or 16 bytes (4 or 8 data words), which must betaken into account when the addresses are allocated.Please refer to the host controller board user manuals for a detailed descriptionof logical addressing.

There is no relationship between the base address of the communication inter-face board and the host controller board address window set in the host system(master). Both can be freely selected; i.e. they may even be identical.

3.1 INTERBUS I/O Representations

Owing to the different types of handling and representation of data structures,which are due to the use of different processors (e.g. Intel, Motorola), there is nostandard location of the data bytes at the INTERBUS I/O modules in connectionwith the different PLC and computer makes. Figure 3-2 shows the locations ofthe data bytes depending on the PLC or computer system.

4 Detecting Error ConditionsWith Communication Register 0

Scanning communication register 0 gives the user the opportunity to respond to error conditions in the slave or master system.

A feature of the communication register 0 on the communication interface board is that it is cleared in a direction-dependent manner should slave or master er-rors occur. This is due to the fact that bit 7 can be used in both directions for sig-naling the error conditions.

Figure 4-1 shows the location of the communication register 0 in the data word. You can see that bits 8 to 15 of the first data word are assigned to this register.

Figure 4-1: Representation of registers 0 and 1 in the first data word

Bit 7 of the communication register is assigned to bit 15 of the data word. This applies, according to the signaling direction, to the input and output area of the S5 system.

As has been mentioned in Section 3, the arrangement of the bytes in the data word may vary depending on the controller board used.

The locations of the jumpers (jumpers X3 to X5 and X7 to X11) are shown in Fig-ure 5-1.

Figure 5-1: Locations of the jumpers on the communication interface board

5.2 Jumper Settings

The jumpers allow the user to respond to fault conditions in the slave or in themaster system. As a result there are two message directions:

- Fault conditions in the slave system which can be reported to the master sys-tem

- Fault conditions in the master system, including the associated INTERBUS, to which the slave system can respond.

5.2.1 Master System Failure

When the INTERBUS system fails or a remote or local bus is reset, all commu-nication registers are reset. For bit 7 of the communication register 0 this is only true if the jumper X4 (Figure 5-2) is in position 2-3.

Figure 5-2: Jumper X4 (Default position 2-3: In this position all communication registers are reset)

When the user puts jumper X4 in position 1-2, bit 7 of the communication regis-ter 0 shows a "1" during an active bus reset. If the slave system is to respond to a malfunction of the master, the user mustset X4 to position 1-2, and scan bit 7 of the communication register 0 in the slaveinput area.If this bit is to be used for data transfer as well, jumper X4 must remain in posi-tion 2-3 (default state). If jumper X4 is in position 2-3 and a master system failure occurs, the slave sys-tem receives on all bits the output value of the master system.When the master sytem fails, most host controller boards set the OUT data to"0". This is also true for the communication register data. Thus, the user is ableto recognize a master system failure (see description of communication register0).

5.2.2 Slave System Failure

In case of an S5 failure, the signal BASP at the control sytem is activated. In theslave system all digital outputs are set to the state "0". In addition, every statechange of the BASP signal results in a module status error when jumper X11 isin position 1-2 (see Section 5.2.4). The user cannot manipulate this behavior of the communication interface boardand the INTERBUS system.

When the voltage of the slave PLC fails, the words 5 to 8 transferred by the mas-ter system are returned by the slave as IN data!

RES

INTERBUSSwapping Bytes in the Word (SWAP)

5-55004C

The master system can respond in different ways to the module status error re-ported by the slave board:- If the master system is switched to the "STOP" state after an error, further in-

formation is not required.- However, if the master system is to continue to operate, the current BASP

signal state of the slave system must be transmitted. Bit 7 in the communication register 0 is used to indicate the BASP signal.

Jumper X3 allows to use bit 7 for data transfer (position 2-3 of X3) or for over-laying the BASP signal (position 1-2 of X3) If jumper X3 is in position 2-3, alleight bits of the communication register 0 can be used for data transfer. (Figure 5-3)

Figure 5-3: Jumper X3 (Default position 1-2: Mapping in the BASP signal)

5.2.3 Swapping Bytes in the Word (SWAP)

As the different master systems interpret the order of bytes in the data word dif-ferently, (Section 3), an adaptation to the master system is essential. This isnecessary, for example, with the Bosch PLC or with a PC that functions as amaster. The conversion is effected with jumper X5 (Figure 5-4).In position 1-2, no bytes in the word are swapped. The order of writing/readingis first high-byte, then low-byte.

Figure 5-4: Jumper X5 (Default position 1-2: Bytes in the word are not swapped )

Accordingly, position 2-3 means a reversed order of reading/writing.

5.2.4 Bus Master Information on Active BASP Signal or PLC Voltage Failure

When X11 is in position 2-3 (Figure 5-5), an active BASP signal or a PLC voltagefailure is indicated as a module status error to the bus master. The error LED islit.

Figure 5-5: Jumper X11 (Information of the bus master on an active BASP signal or PLC voltage failure)

Position 1-2 disables this function.

5.2.5 Operation in the Central Controller/Central Expansion Unit

It is possible to connect an expansion unit to the SIMATIC® S5 system. As thecommunication interface board can be operated in the basic unit as well as inthe expansion unit, the address lines A8 to A11 must be dealt with separately.When the communication interface board is installed in the basic unit, the jump-ers X7 to X10 (Figure 5-6) must be set to position 1-2. Therewith, the lines areconnected 1:1 with the SIMATIC® S5 bus.

Figure 5-6: Jumpers X7-X10

When the communication interface board is installed in the central expansion unit, place the jumpers X7 to X10 in position 2-3. Here, the address lines are not used and are connected to ground.

7 INTERBUS Connection and Diagnostic LEDs

7.1 INTERBUS Connection

In the INTERBUS system, the IBS S5 SL LB communication interface board isconnected as a local bus module. The local bus cable is connected directly tothe board.The logic circuitries both on the bus side and on the PLC side are electrically iso-lated from one another.

For connecting the incoming local bus cable, the communication interface boardfeatures a 15-position male D-SUB connector (LOCAL IN), and for the outgoingcable a 15-position female D-SUB connector (LOCAL OUT). Preassembled ca-bles are available in the following lengths: 10 cm, 20 cm, 50 cm, 100 cm and150 cm .

Table 7-1: Preassembled cables

- Length of the local bus: 10 m- Length of each local bus cable: max. 1.5 m- Up to 8 modules in a local bus branch together with the IBS S5 SL LB board

7.2 Diagnostic LEDs

Two light-emitting diodes, called "Error" and "Us" indicate the operating mode ofthe communication interface board. These four LEDs have the following mean-ings:

Us:The green LED is on when the logic voltage is applied to the communication in-terface board.

Error:It depends on the position of the jumper X11 whether this display appears. When an S5 system fails, the BASP signal of the PLC is activated. When BASPis active, this is indicated by the "Error" LED. The the same is true in the eventof a voltage drop at the PLC.Both is only the case in position 2-3 (see also Section 5.2.4).

If the jumper X11 is in the position 1-2, neither the STOP state of the PLC nor aPLC voltage failure is indicated to the master sytem. The "Error" LED is not lit.
