RS485 modbus

PLCnext Engineer

Hi I have a problem with a RS485UNI card. I have configured the plc as per the example it works fine for a while but every few hours I get a error on the UNI_send or UNI_RCV functions. When I deactivate and activate the function again the error is still there. The only way to get it to work is to do a power cycle! I tried to find the Warm_Restart function but it is not available!
