EtherNet/IP Indicator Lights
The PM has four indicator lights on the top of the controller, all of which are used with EtherNet/IP. The
characteristics of the Module Status and Network Status LED’s are defined by Open DeviceNet Vendors As-
sociation (ODVA), while the Active and Link indicator lights are defined in the Ethernet specification.

If the device cannot determine link speed or power is off,
the network status indicator shall be steady off.
Red Link speed = 10 Mbit
If the device is communicating at 10 Mbit, the link LED
will be red..
Green Link speed = 100 Mbit
If the device is communicating at 100 Mbit, the link LED
will be green.
