Hi Thomas, thanks for your reply. I have just one TCP connection with some requests to a datablock. I monitored the communication and saw timings for 432 bytes between 16ms up to 47 ms Problem for me is to give you exact data about the previous status - I never controlled the timing before. Don't waste too much of your time to investigated around this issue. I am able to workaround for this moment. Just keep it in mind, if somebody else have same experienes. Best regards

Hi, I am using nettoplcsim successfully since many years to connect my simulation applications to PLCSIM. SInce one of the last Windows 10 updates I am mentioning heavy delays in communication which I cannot understand. The PLC program + Application whrere not changed, but the (read) transfer was growing from below 1 secaond to 3-4 seconds . Does there already exist any experiences? nettoplcsim : 1.2.4.0 PLCSIM : V5.4 + SP8 libnodave : 0.8.5 Windows : 10 Pro Version 21H1 Build 19043.1052 Any hints...
