Here is solution for S7PLC connect to PLCSIM Compact, comment in S7Interface disconection timeout.
SetPDU to 10 (working not stable and max 5 byte in, 5 byte out)
And using Nettoplcsim-S7o-v-1-2-4-0 program
Some features in configs NetToPlcsim

Hello，I want to use PLCSIM connect unity because it support S7-1200CPU without real PLC，witch Interface should I use？PLCSIMADV or S7Interface？Should I set something in Portal or unity？Thank you！
PLCSIM is not officially supported. PLCSIM Advanced interface won't work with PLCSIM. But you can follow the guide apove and make it work with Nettoplcsim (see post above) and G4A S7-TCPIP interface . but it is not an official and supported solution from our side.
Thank you Thomas，I will try it。
