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 appreciated...

At the moment I've got no idea. I'll check if I have the same Windows version somewhere available where I can make some tests.
Do you have one or more TCP connections to Nettoplcsim? Is a simple single request (e.g. DB1.DBW0) also slow?
If you enable the monitor window in Nettoplcsim, does the message occur directly after your request, or is there a delay?

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
