What to do if node number does not agree with host ID in Omron CS1W-ETN01 Controller?
To resolve the issue where the node number set on the rotary switch of your Omron Controller doesn't match the host ID in the IP address, ensure the node number and the last byte of the IP address are the same, and set other host IDs to 0. Alternatively, change the address conversion method.
What to do if my Omron Controller Ethernet Unit is faulty?
