Allen-Bradley · Compact 5000 Digital I/O Modules
The Group A or Group B indicator is off, meaning the I/O status indicators are currently not showing the status for that specific group of channels. This is not necessarily a fault but rather a display state of the module.

Press the physical Group A or Group B button on the module faceplate to display the I/O status for the desired group of channels.
