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
The UA-OFF monitoring board sends an identifier-related diagnostic message to the bus coupler,
which signalizes that the actuator voltage (UA) has fallen below the minimum (UA < UA-OFF).
It shows the number of the slot where the error occurred. The diagnostic message consists of one
diagnostic bit.
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).
8.3
Parameter data
The electrical UA-OFF monitoring board does not have parameters.
