Note If there is a routing table in the CS/CJ-series CPU Unit, the DeviceNet Unit must be registered in it when replacing the C200HW-DRM21-V1 with the CS1W-DRM21 or CJ1W-DRM21. If the DeviceNet Unit is not registered, it will result in a routing table error, and the 7-segment display of the DeviceNet Unit will indi- cate “HC”.
