1.4.3 2.1 LED Operation

A 2085sc-OF8 module with Version 2.1 firmware uses a single, green OK LED
to show power or module operational status:
• When startup is completed, and all internal tests have passed, the LED is
solid GREEN. This indicates RUN mode.
• If the LED remains off, there is an error with the module: it may not have
power or failed to pass the self-test.
• Any time the system is not in Run mode (and showing no faults), the
LED blinks rapidly, indicating the module is Offline. All inputs and
outputs are disabled in this instance.
The LED identifies different conditions using specific, numeric, blink patterns.
The module blinks a specific number of times, pauses, and then repeats the same
blink pattern indefinitely. Blink codes are shown in the following table.
