hi hankbiao,

Simatic-H-Station are not supported by PLC-Sim.

this is mentioned in the help of PLCSim,

and also in this FAQ:

What is the difference between S7-PLCSIM and a "real" automation system?

hope this helps,

regards,

Hi,

I had the same problem and I solved by remove and re-install the PLCSIM
