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

7.2.1

Cyclical diagnostic data

The electrical supply plate sends the diagnostic message as a group diagnosis with the input data
to the bus coupler (see Table 14). The diagnostic bit for the corresponding module (module number)
indicates where the fault occurred. The diagnostic message consists of a diagnostic bit that is set
when the actuator voltage falls below 21.6 V (24 V DC -10% = UA-ON).
The diagnostic bit can be read as follows:
Bit = 1: An error has occurred (UA < UA-ON).
Bit = 0: No error has occurred (UA > UA-ON).
7.2.2

Acyclical diagnostic data (explicit messages)

The electrical supply plate diagnostic data can be read out like the valve driver diagnostic data
(see section 6.2.2 "Acyclical diagnostic data of the valve drivers (explicit messages)" on page 95).
7.3 Parameter data
The electrical supply plate does not have any parameters.
