仿真1756-module问题？
设置一下1756-MODULE，槽号跟Emulate 5000 一致！如下设置：
For read/write connections:        For listen only connections:
Input Assembly Instance1           Input Assembly Instance1
Input Size2                        Input Size2
Output Assembly Instance2          Output Assembly Instance3
Output Size1                       Output Size1
Configuration Assembly Instance16  Configuration Assembly Instance16
Configuration Size0                Configuration Size0


Specify the Requested Packet Interval (RPI).
You must enter at least 50.0 ms for the RPI.  The connection will fail if the RPI is less than 50 ms.  Because this module uses the generic module profile, the default RPI is 5.0 ms.  You must change this value
请问高手For read/write connections:        For listen only connections:
Input Assembly Instance1           Input Assembly Instance1
Input Size2                        Input Size2
Output Assembly Instance2          Output Assembly Instance3
Output Size1                       Output Size1
Configuration Assembly Instance16  Configuration Assembly Instance16
Configuration Size0
这里面的Input Assembly Instance1           ，Input Size2                        ，还有下面的output，Configuration Assembly Instance16，Configuration Size0 ，里面的参数分别是什么意思？
