In the following block, the system error codes of the KE as well as (in series) the system error codes of
the channels are transmitted (see table 6–178).
Transmission of system error codes is realized in series by means of the handshake signals. In addition,
the error status of PLUS coupling is returned in Plus_ErrCode (if an error occurs).
The following error codes are possible:
• 0: No error
• 1: Invalid type number
• 2: Error during type number decoding
• 3: PQD transmission error (no communication)
• 4: PQD transmission error (PLUS response)
• 5: PLUS communication interrupted, PLUS data service not active or PLUS not (yet) initialized
