Communication Issue between Q-series mitsubishi PLC and Thigworx Kepware Server

Greetings @GC_11210517, 

I hope you're doing well.

I would request you kindly follow to the below steps to troubleshoot and resolve the problem:

1. Check Connection Status: Verify that the ThingWorx Kepware Server is properly connected to the PLC. You can do this by checking the connection status in the ThingWorx Kepware Server configuration.
2. Restart Services: Sometimes, simply restarting the ThingWorx Kepware Server service can resolve connectivity issues. Ensure that the service is running smoothly.
3. Firewall and Network Settings: Ensure that there are no firewall or network settings blocking the communication between the ThingWorx Kepware Server and the PLC. Since the KEPServerEX is working, compare the network settings for both servers.
4. Driver Settings: Double-check the driver settings in the ThingWorx Kepware Server. Ensure that the Mitsubishi Ethernet driver is configured correctly and matches the settings in KEPServerEX.
5. Reconfigure Device: As a last resort, try deleting and reconfiguring the device in the Thingworx Kepware Server. This can sometimes resolve configuration issues that are not immediately apparent.
