PLC Connect and Modbus/TCP
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?
This might be helpful in debugging.
