To display information about the current operating state, the communication board
has a 3-color LED (green, orange, red).
Its voltage is supplied via the converter system connector.
Alternatively, an external 24 V connection can supply the voltage for the
PROFIBUS optional board and converter electronics.
The board is connected to the PROFIBUS system via a 9-pin sub D socket
connector complying with the PROFIBUS standard. All connections to this RS485
interface are short-circuit-proof and isolated.
