I'm trying out SCAD-LTS with my trusty Modbus simulator ModRSim2.exe as a Docker image on a Windows 10 laptop. I'm having difficulty maintaining a stable connection to the Modbus TCP server. Update rate is at 1s. Data is beeing read, but alarms keep popping up (connection lost, checksum) and the connection keeps beeing reset.

The checkbox is for encapsulating the Modbus RTU protocol in TCP data packets. Checking the checkbox was a bad idea (although it seemed to reduce the number of errors it actually made things a lot worse). I ended up increasing the cycle time from 1 to 2 seconds. That made the error messages go away. Weird, because I would not expect protocol errors to arise from short cycle times. I think it might be a bug(?)
