INTERBUS Process Data in the PLC
The I/O address area of the SIMATIC®S7-300 PLC depends
on the type of CPU. It is split into an input and an output
addressarea. Thesecontain the data of the boards operated
in the PLC.
Driver blocks allow the area of the INTERBUS process data
(input and output data of INTERBUS devices) to be
transferred into or out of the S7-300 PLCblock by block. The
driver blocks create a process image that reads the inputs
prior to the application program, andwrites the outputs to the
controller board or output devices after they have been
processed by the application program.
The driver can transfer the input/output data of the
INTERBUS system into the I/Q area of the PLC, bit memory
areas or data blocks, or out of these areas.

Remote Bus Connection (REMOTE)
The remote bus interface connects the controller board with
the INTERBUS devices (field devices). The remote bus
connection on the front plate of the controller board has been
designed as a 9-pos. D-SUB female connector. Phoenix
Contact offers pre-assembled remote bus cables in common
lengths. The pinout of the remote bus cable connector is
shown in the figure below.
Figure 2 Remote bus connection and example of a
remote bus cable (cable type D9/D9)
The IBS OPTOSUB... and OPTOSUB PLUS interface
connectors enable you to fit your INTERBUS system with
optical fibers. Interface connectors are available for different
mounting positions. Please refer to "Connecting Cable" on
page 62 in the Appendix of this Quick Start Guide.
Diagnostic Interface (RS-232)
The controller board’s serial interface (RS-232) connects an
IBM-compatible PC with the IBS CMD SWT G4 E software
(Order No. 27 21 44 2). This software can be used to
configure, parameterize, and diagnose the INTERBUS
system. IBS CMD SWT G4 E is independent of the
programminglanguageortheoperatingsystemoftheS7-300
PLC.

on the parameterization memory (available as an accessory
part) with IBS CMD SWT G4 E. In addition, upgraded
firmware for the controller board can be downloaded. The

Installing the Controller Board
Possible Slots
The S7-300 PLC is row-oriented with amaximum of four rows
(0 through 3). Each row has a maximum of eight slots for I/O
modules.
Figure 9 Structure of a SIMATIC®S7-300 PLC
Rules for the Use of the Controller Board
The controller board can be operated in rows 0 through 3
(rows 1 through 3 for C7, SINUMERIK 810D and 840D PLCs)
in slots 4 through 11. The maximum number is two controller
boards per row.
Current consumption of the controller board:
ThecontrollerboardoccupiesoneslotintheanalogPLCarea
(16 byte inputs and 16 byte outputs).
Please note that the limited system resources of the
S7 CPU 312 prevent the controller board from being
operated in a PLC with this type of processor.

Connect the controller board to the PLC power supply
unit. In thiscase, the controller board will also bereset
on a PLC POWER-UP.
Inserting the Parameterization Memory
Please note that only the test mode enables the
operation of the controller board without
parameterization memory. During normal operation a
parameterization memory must be inserted.
Figure 14 Inserting the parameterization memory
Inserting the Parameterization Memory
Insert the parameterization memory into the slot provided,
with the female connector to the front (see Figure 14). Make
sure that when the parameterization memory is pressed
lightly it clicks into place and the ejector moves out.
As you insert the parameterization memory, make
certain that the card is located in the guide rails on
both sides of the card holder. Make sure that the
parameterization memory is properly aligned.
Removing the Parameterization Memory
Press the ejector. The parameterization memory will be
ejected from the slot. You can then remove it from the front.

Connecting the INTERBUS System
Connect the remote bus cable which goes to the first
INTERBUS bus terminal module (BK module) to the remote
bus interface (REMOTE) on the controller board. The
connection to the controller board is via a 9-pos. D-SUB
female connector, into whichyou can insert either the remote
buscableoran adapterforconversiontofiberopticcable.For
further information on the bus cable assembly and optical
fiberadapters,pleasereferto "Connecting Cable"onpage 62
as part of the Appendix.
Use only metal-plated connector housings.
