Hi I have an amsamotion fx3u-26mr plc and an op320-a-s panel I wrote a simple program that every second increases the DO value by 1 on the plc works correctly but on the panel the parameter always remains at 0
The exchange via rs485 works correctly, the inputs, the outputs and the memory exchange the values between op and plc while the D parameters are not transferred.
can anyone help me?
thank you
