默認(rèn)條件：如果中央單元07 KR 91/07 KT 92/07 KT93/07 KR 31/07 KT 31切換至“從”模式”，它們的行為類似于二進(jìn)制輸入和輸出模塊當(dāng)連接到CS31系統(tǒng)總線。
這意味著傳輸和接收范圍在主設(shè)備的二進(jìn)制范圍內(nèi)。
它們的大小為每個(gè)32位（4字節(jié)）。對(duì)于n=4的從機(jī)地址，以下適用于例子：07 KR 91的輸出信號(hào)AW 00,00用作slave是所用07 KR 91的輸入信號(hào)EW 04,00作為總線主控。

slave central unit via the CS31 system bus. The
communication between master and slave is performed
using input and output operands.
All the master data are consistently transferred to the
slave, and all the slave data are consistently transferred
to the master.
The slave PLC can be used either in the binary range or in
the word range of the CS31 system bus. The transmit and
receive ranges of the slave can be adapted to the
application-specific requirements by means of the two
system constants KW 00,10 and KW 00,11 (see also
chapter ”System constants”).
You can set:
– The size of the transmit and receive ranges and
– the mode of employment of the slave (in the binary or
the word range).
Default condition:
If the central units 07 KR 91 / 07 KT 92 / 07 KT 93 /
07 KR 31 / 07 KT 31 are switched over to the ”slave
mode”, they behave like binary input and output modules
with 32 inputs and 32 outputs when connected to the
CS31 system bus.
This means that the default setting of the transmit and
receive ranges is within the binary range of the master.
Their size is 32 bits each (4 bytes)For the slave address of n = 4 the following applies, for
example:
The output signal AW 00,00 of the 07 KR 91 used as
slave is the input signal EW 04,00 for the 07 KR 91 used
as bus master.
A2.7 Special modules used as slave on the
CS31 system bus
Robot coupler ICBG32L7 and ICBG64L7
The Robot coupler ICBG32L7 (ICBG64L7) behaves on
the CS31 system bus like a binary input/output module
equipped with 16 (32) inputs and 16 (32) outputs.
The module address can be set by means of the DIL
switch on the printed circuit board.
The meaning of the DIL switch is the same as that on the
plug-in base ECZ, see chapter A2.3. Switch No. 8 is
always set to OFF.
Please note that the set module address and also the
following address are assigned by the Robot coupler
ICBG64L7.
For the signal names in the user program of the central
unit, please see the description of the Robot couplers.
Festo valve island/installation island
The Festo valve island and the Festo installation island
behave on the CS31 system bus like binary input and
output modules. For the scope of assigned data, please
see chapter A2.9.
The module addresses are set by means of the address
switches located below the cover of the ”field bus node”.
The upper switch is provided for the unit digit, the lower
switch for the tens digit.
