3.1.11 LED Display
Fieldbus Controller
Fieldbus Controller 750-841
The controller has several LED’s for a visual display of the controller and
nodes operating status.
Fig. 3.1-15:
The LEDs can be divided into three groups.
The first group of LEDs display the status of the Ethernet fieldbus. It contains
both solid and two-color LEDs. They are labelled as: ‘LINK‘ (green), ‘MS‘
(red/green), ‘NS‘ (red/green), and ‘TxD/RxD‘ (green).
The second group of LEDs are three-color LEDs (red/green/orange). One of
the LED is labelled ‘I/O’, and displays the status of the internal bus. The
other is labelled ‘USR’, and is programmable with WAGO-I/O-PRO CAA.
The third group uses solid colored LEDs. They are located on the right-hand
side of the controller power supply. These display the status of the supply
voltage.
