Hi, I have implemented Modbus TCP Slave, that works. But only 30 minutes and then we have to shut down PLC and reboot.
I used INVTMatic studio, PLC is AX70, and library for Modbus Slave is from 3S - Smart SW Solutions Gmbh. So that solution functions but I have orange flag next to it. That means that it is running in demo mode. I was thinking this means I need license. I also bought license on 3S , but still same thing and same fault. Anybody tried something similar?
