What to do if Omron SYSMAC CJ1W-EIP21 shows a Duplicate unit number?
If the same unit number is set on another Unit, set the unit numbers correctly and restart the EtherNet/IP Unit or built-in EtherNet/IP port.
Why does Omron Network Hardware show a CPU Unit event servicing timeout, and how to fix it?
If a timeout occurred during an operation such as reading the routing tables to the CPU Unit, replace the EtherNet/IP Unit or (for a built-in EtherNet/IP port) the CPU Unit if the error recurs when the Unit is restarted.
What to do if Omron SYSMAC CJ1W-EIP21 reports a Verification Error (target non-existent)?
If the target registered in the device parameters does not exist, check the following items: * Is the registered node’s power supply ON? * Is the cable connected? * Is the cable damaged or loose? * Is there excessive noise?
