Structure of Pneumatic Supply Plate Data
with UA-OFF Monitoring Board
The electrical UA-OFF monitoring board transfers all signals including the supply voltages.
The UA-OFF monitoring board recognizes whether the UA voltage falls below the UA-OFF value.
8.1
Process data
The electrical UA-OFF monitoring board does not have process data.
8.2
Diagnostic data
8.2.1
Cyclical diagnostic data
The UA-OFF monitoring board 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 UA-OFF.
The diagnostic bit can be read as follows:
Bit = 1: An error has occurred (UA < UA-OFF).
Bit = 0: No error has occurred (UA > UA-OFF).
8.2.2
Acyclical diagnostic data (explicit messages)
The diagnostic data of the UA-OFF monitoring board 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).
8.3
Parameter data
The electrical UA-OFF monitoring board does not have parameters.
