EtherNet/IP
5.2 Diagnostics
Behavior of the LEDs RN/NS (RUN/network status), ER/MS (ERROR/module status) and MT/IO
(MAINT/IO status) on EtherNet/IP
The LEDs display the status with the highest priority if there are different LED states due to
overlaid events. (0 = off, 1 = green flashing, 2 = green, 3 = yellow, 4 = red flashing, 5 = red)
The following table shows the meaning of the RN/NS, ER/MS LEDs and MT/IO LEDs for
EtherNet/IP:
