PLC Connect and Modbus/TCP
Hello,
we installed a 800xA system (800xA 5.1 FP4) with the PLC Connect to communicate in Modbus TCP/IP with 6 devices. I configured the Modbus TCP/IP drives as show in the file attached "Setup_Driver_Modbus.jpg" bellow (Poll Cycle = 5 sec, timeout = 2000 ms etc.). After I configured the update interval (6 sec.), please see the file "Update_Interval.jpg", and I configure some log configuration for read the values in the trends.
I have a problem because sometimes the communication with a device is bad (signal quality Bad), please see the interruption in trend (image Trend_with_Interruptions.jpg).
The interruptions do not occur in the same time in all devices but are random.
Do You have any suggestions?
Thanks,
Al

If possible, share PLC Connect log files from path: C:\OperateITDataXXX\AdsServer, along with the appropriate time when the communication break is occurring. Also, send screenshots of PLC Connect configuration settings. This might be helpful in debugging.If possible, share PLC Connect log files from path: C:\OperateITDataXXX\AdsServer, along with the appropriate time when the communication break is occurring.
