Data Structure of the Electrical Supply Plate

7 Data Structure of the Electrical Supply Plate
The electrical supply plate interrupts the UA voltage coming from the left and transfers the voltage
supplied by the additional M12 plug to the right. All other signals are directly passed on.
7.1

Process data

The electrical supply plate does not have any process data.
7.2

Diagnostic data

The electrical supply plate sends a manufacturer-specific diagnostic message to the bus coupler,
which indicates a missing actuator voltage (UA) or that the system has fallen below the tolerance
value of 21.6 V DC (24 V DC -10% = UA-ON).
The diagnosis is structured as follows:
In the User Structure Identifier (USI) (first 16-bit value), the slot number is coded and 0x0040 is sent
in the diagnostic data (second 16-bit value). This corresponds to a group diagnosis.
If several diagnoses are available, for example if a short circuit is detected in several modules,
each diagnosis is set and also reset individually.
7.3

Parameter data

The electrical supply plate does not have any parameters.
