产品详情介绍
D20-PS LFDSC143-4000通用电气卡件
无法直接访问通过CS31系统总线从中央单元。这个执行主设备和从设备之间的通信使用输入和输出操作数。所有主数据都一致地传输到slave，并且所有slave数据都被一致传输向大师致敬。
从PLC可用于二进制范围或CS31系统总线的字范围。传输和从设备的接收范围可以适应应用程序特定要求
系统常数KW 00,10和KW 00,11（另见“系统常数”一章）。
您可以设置：–发送和接收范围的大小以及
-奴隶的雇佣模式（二进制或单词范围）。
默认条件：如果中央单元07 KR 91/07 KT 92/07 KT93/07 KR 31/07 KT 31切换至“从”模式”，它们的行为类似于二进制输入和输出模块当连接到CS31系统总线。
这意味着传输和接收范围在主设备的二进制范围内。
它们的大小为每个32位（4字节）。对于n=4的从机地址，以下适用于例子：07 KR 91的输出信号AW 00,00用作slave是所用07 KR 91的输入信号EW 04,00作为总线主控。

机器人耦合器ICBG32L7和ICBG64L7
机器人耦合器ICBG32L7（ICBG64L7）在CS31系统总线类似于二进制输入/输出模块配备16（32）个输入和16（32”）个输出。模块地址可通过DIL设置打开印刷电路板。
DIL开关的含义与插入式底座ECZ，见第A2.3章。8号开关为始终设置为OFF。请注意，设置的模块地址以及以下地址由机器人耦合器分配ICBG64L7。对于中央用户程序中的信号名称单元，请参见机器人耦合器的说明。费斯托阀岛/安装岛费斯托阀岛和费斯托安装岛在CS31系统总线上的行为类似于二进制输入和输出模块。对于指定数据的范围，请见第A2.9章。模块地址通过地址设置位于“现场总线节点”盖板下方的开关。上部开关用于单位数字，下部开关用于切为十位数。A2.8复杂结构示例，包括地址模块的分类I/O端子There is no direct access to the inputs and outputs of the
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.
