From the manual for PLCSIM version 5.4: S7-PLCSIM

3.3.2 Supported communication blocks

Multiple start capability of S7-PLCSIM V.5.4 with communication support between the CPUs

Several CPUs can be simulated at the same time with the new function. These different CPUs can communicate with each other if an appropriate hardware configuration has been loaded beforehand. This requires unique addresses of the CPUs in the same subnet.

The communication between the CPUs supports the following communication blocks:

● SFB8 "USEND",

● SFB9 "URCV",

● SFB12 "BSEND"

● SFB13 "BRCV"

● SFB15 "PUT"

● SFB14 "GET"

● SFB19 "START"

● SFB 20 "STOP"

● SFB 22 "STATUS"

● SFB 23 "USTATUS"

Note

S7-PLCSIM is not real-time capable. Time response constraints may occur during the communication
