Bus coupler diagnostic data

The diagnostic data can be turned on or off on the DIP switch DR.3. When delivered the diagnostics
are turned off.
5.6.1

Structure of the diagnostic data

When diagnosis is activated, the bus coupler sends 8 bytes of diagnostic data, which are appended
to the input data of the modules. A valve system consisting of a bus coupler and a module with
2 bytes of input data thus has a total of 10 bytes of input data. A valve system consisting of a bus
coupler and a module without input data has a total of 8 bytes of input data.
The 8 bytes of diagnostic data contain
2 bytes of diagnostic data for the bus coupler and
6 bytes of group diagnostic data for the modules.
The diagnostic data is organized as shown in Table 14.
