Good day,

I have a physical s7-1215C plc that have 2 laptops connected to it, One laptop is used to run WinCC runtime and the other laptop is being used to monitor the PLC. The laptop monitoring the PLC code online keeps getting disconnected, after being online for about 30 seconds. I have checked the IP address of all the devices on the network and there is no conflict between any of them. The laptop running the WinCC runtime has a delay when receiving information from the PLC. I have used TIA v15.1 for both the PLC and SCADA project.

How do I resolve this problem?

Hello,

have you check the diagnostic buffer of PLC if any connection errors are logged?

 Yes, I have it doesn't log the error, under info it just says the connection has been cancelled.
