State
Description
NET
Off
  • The controller is not configured, or does not have an IP address.
  • The port is administratively disabled.
  • In a dual-port controller, the EtherNet/IP mode is Linear/DLR mode. In this case, the NET A2 indicator is off. The NET A1 indicator remains on.

  • No link exists on the port.

  • The port is administratively disabled.
  • In a dual-port controller, LINK A2 only - The controller is the active ring supervisor in a DLR network and has detected a rapid ring fault.
Flashing green
All of these conditions exist:
  • The port is enabled.
  • A link exists. That is, the cable is properly connected to an enabled controller Ethernet port on to another device.
  • There is activity on the port.
Steady green
On a single-port controller, a link exists on the port, but no traffic is being received.
On a dual-port controller, all of these conditions exist:
  • The port is enabled.
  • A link exists. That is, the cable is properly connected to an enabled controller Ethernet port on to another device.
  • LINK A2 only - The controller is the active ring supervisor in a DLR network, and the ring is not broken. This is a normal operation.
