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 where the fault
occurred. The diagnostic message consists of a diagnostic bit, which is set in the event of a short
circuit of an output (group diagnostics).
The diagnostic bit can be read as follows:
Bit = 1: An error has occurred.
Bit = 0: No error has occurred.
6.2.2

Acyclical diagnostic data of the valve drivers (explicit messages)

The diagnostic data of the valve drivers can be read out as follows:
Enter the following values in the PLC configuration software in the corresponding input field.
