I know Simatic S7-1200 don't compact with Simulation ON TIA Portal.
But had somebody had a Software for simulation PLC S7-1200 successful before.

If somebody have it, can share it 4 everyone.SPS-VISU Micro
Create a virtual machine/plant with the integrated construction kit.
The virtual plant has virtual sensors and actuators.
Connect the virtual plant with a real S7-1200 or LOGO! device from SIEMENS.
(SPS-VISU Micro has no own Software-PLC for S7-1200 or LOGO!)
SPS-VISU Micro writes the value of the virtual sensors to the real PLC and read the states of the outputs to dynamize the virtual actuators.
SPS-VISU Micro can be used for PLC training purposes.
Professional developer can use SPS-VISU Micro to find hidden logical bugs in the PLC program.
Thank you so much.
Sorry about my English language.
