LED indication
The MVP12 modules are equipped with the following separate LED indicators:
LED indication for inputs/outputs
LED indication for IO-Link and US sensor supply
LED indication for actuator supply UA (Class B only)
Indication takes place by means of static lighting or flashing of the LEDs.
7.1.1
LED indication US and IO-Link
The device has a combined LED for the IO-Link status and the status of the
US sensor supply. The IO-Link status is mapped by the green LED chip, and
the US status by the red LED chip.
This can give rise to a mixture of green and red flashing codes (in case of over-
lap orange flashing code).
