Hi all, this is my situation :
plc weidmuller UC20 WL200 AC target version 4.12.0.0
codesys 3.5.20.0
Actually i'm testing the program without license (2 hours).
i'm trying to use the function block ModbusServer.
I used it on the past with codesys 3.5.14.40 an it worked.
Now not.
i can connect (as you see byClientConnctions = 1) but i dont recive a reply from server.
Someone can help me?
Hi, again
after spending a lot of time finding more information with no results, by chance I changed the device ID from 1 to 255 and the transmission works.
Unfortunately the documentation is very very poor.

I've always liked codesys, but sometimes it drives me crazy

:) Yeah...
Definitely not a "boring" platform, they are nice to give us work for the upcoming years... :)
