I try to used cx-supervisor for read-write data from plc unitronic by Unitronic OPC server .But i cannot read or write data , i think that i set group,item,path not correct.I see status at opc server , it show that " have new client connect ". When i run cx-supervisor , it show that " fail add item to plc " .If someone have experience about had used cx-supervisor read-write data other plc ( not omron) by OPC server , please advice me.
