Why am I unable to communicate with my PC or other non-remote I/O device, which is connected to an Ethernet port(s) (on a DRS or a ••• CR• 312 •0 module)

Possible cause:
  • The PC or other non-remote I/O device may be connected to the wrong remote I/O module port.
Possible solution:
  • Check that the PC or other non-remote I/O device is connected to one of the following:
    • a DRS — DIO Cloud or DIO Sub Ring port
    • a 140 CRP 312 00 module — INTERLINK port or SERVICE port configured as an access port
    • a ••• CRA 312 •0 adapter module — SERVICE port configured as an access port
NOTE: Do not connect a device with a speed in excess of 100 Mbps to the SERVICE port. If the device is configured for a speed that exceeds 100 Mbps, the Ethernet link may not be established between the device and the module through the SERVICE port.
