Central IO Module LEDs
The Central IO modules have the following status indicator LEDs on the front of the module:
I/O Module Status LED
I/O Channel Status LEDs
Central IO Module Status LED
Each Central IO module contains a green/red Status LED that indicates the status of the module in relationship to the automation server. The LED is labeled Status and is located on the lower right side of the Central IO module placard.
The Central IO module Status LED indicates the condition of the device.

I/O Channel Status LEDs
Each digital input (DI) channel, digital output (DO) channel, and Universal Input (UI) channel contains a green I/O channel status LED. This LED indicates the On/Off state of the digital input or output.
You can also configure I/O channel status LEDs as an invert, so that either a HIGH or LOW voltage level can turn the LED ON.
For Universal Inputs, the I/O Channel Status LED is active only if the channel is configured as a digital input or as a counter input.
