Dear colleagues,

I would like to know if is possible to use the PLCsim in conjunction with a Simatic Field PG M2 to be used as PROFIBUS master, for some drives.

The application is only for training classroom proposes.

I’ve seen other threads saying: in the last version of PLCsim is possible simulate more than one CPU at the same time, to simulate communication between them.

How can be the PLCsim PROFIBUS port be routed to the CP5611 integrated in the PG?

Do you know any example?

Thanks in advance!!

Further differences

The simulated PLC does not provide the following functionalities that are available in a "real" PLC:

• Diagnostic buffer: S7-PLCSIM does not support all of the error messages written to the diagnostic buffer. For instance, messages relating to bad batteries in the CPU or EPROM errors cannot be simulated. However, most I/O and program errors can be simulated.

• A change of operating mode does not change the I/O to a "safe" state.

• Function modules (FMs) are not supported.

• Point-to-point communication (such as between two S7-400 CPUs in the same rack) is not supported.

• S7-PLCSIM does not support forcing variables.

• S7-PLCSIM executes some SFBs and SFCs in the same way as a real S7 PLC; For others, S7-PLCSIM validates input parameters and returns output that is valid, but not necessarily what a real S7 PLC with a physical I/O would return; and otherwise S7-PLCSIM treats the remainder as NOPs.

• Multicomputing is not supported by S7-PLCSIM: S7-PLCSIM cannot simulate SIMATIC stations with several CPUs (multicomputing).

• H systems are not supported by S7-PLCSIM.
