Hello
Can you give me an advice how to solve the problem.Well,I have PLC Jazz 20 R31
connected to modem(Scada) by RS485(Modbus protocol). Everything works but from time to time the communication between the devices disappears and I have to reset the PLC If I wanna restore the communication. It happens often when some unit(pumps) is switched on.
The file with my Modbus config is attached
How to solve the problem?
Sincerely Wladimir
