For simplex WIOCs, Off could indicate that the WIOC lacks active Ethernet communications. Check the cable and network switch connections. For redundant WIOCs, Off could indicate that the I/O Port is not properly seated or that the I/O Port needs to be replaced. Also for redundant WIOCs, Off could indicate that the WIOCs are configured for redundant operation and simplex communication. |
