关于S7/1200系列configuration control是否支持通讯卡，咨询了德国西门子的技术支持，得到的回复是：All what can be plugged in on the left side of the PLC, every kind of a CP, can't be switched away by data record and still needs to be set in the option handling.
For example a CP is plugged in in slot 101, so this one must assigned with 101.
( In the device configurtion available CP cannot be swichted away with a 0 )
A not projected CP is still assigned with 255

我理解的是所有控制器左边位置的模块均不可以进行configuration control。

所以请您再核实一下！
