Display Elements

The operating condition of the fieldbus controller or the node is displayed with the
help of illuminated indicators in the form of light-emitting diodes (LEDs).
The LED information is routed to the top of the case by light fibres. In some
cases, these are multi-colored (red, green or red/green (=orange)).

+ For the diagnostics of the different domains fieldbus, node and supply voltage,
the LEDs can be divided into three groups:
