Status LEDs
When the device is operating, the operational status of the connections is indicated
visually by status LEDs.
Using these status indicators, the operator can find out quickly and easily whether the
device and the peripherals are working properly or whether any faults or errors have
occurred.
Monitoring the visual indicators is part of the routine inspection carried out on the
device and the machine/plant area into which the device is incorporated.
