Hello, I have version 6.2.0.0 installed in Windows 10
I made a test project with modbus TCP
When starting the connection, it correctly makes the first 76 queries and then the communication fails.

When applying restart line it again correctly does the first 76 queries and then communication fails.
The TCP server used works well with other scada software.
