SERCOS CARD LED INDICATORS
The module's three LED indicators show the state of the system. The
LEDs are located on the bezel of the 1756-M08SE and the
1756-M16SE modules. The LED on the right, marked by OK, indicates
the present health of the module and the communication status. To the
immediate left of the OK LED is the SERCOS Ring LED, which is
marked with a ring icon and displays the status of the SERCOS net-
work. The CP LED, on the left, displays the status of the SERCOS
Communication Phases and is for informational purposes only.
During power up, the module completes a self test that includes an
indicator test. All LEDs go red for one second, green for one second,
and off for one second.
