Diagnostic data

6.2.1

Cyclical diagnostic data of the valve drivers

The valve driver sends the diagnostic message with the input data to the bus coupler (see Table 14).
The diagnostic bit for the corresponding module (module number) indicates that an output
short-circuit has occurred in the valve driver (group diagnosis).
The diagnosis bit can be read as follows:
Bit = 1: An error has occurred.
Bit = 0: No error has occurred.
