Issue:
Error message when attempting to connect to a PLC.
Product LIne:
Control Expert software (formerly Unity Pro )
Resolution:
This error means simply means that whatever address you are looking for is not responding. You would get this same error if trying to connect with no cable or if the cable you are using is bad.
In the 'Set Address' box, make sure that the check mark is next to PLC and not simulator.
Check for a Typo in address field.
Verify that communications protocol is working properly, USB, Modbus Plus, correct Ethernet address(make sure ping responds), etc.
If using the USB port on an M340, Quantum or M580 CPU, the address is SYS and Media is USB.
