Bus coupler diagnostic data

5.6.1

Structure of the diagnostic data

The bus coupler sends 8 bytes of diagnostic data, distributed across two input objects, that are
appended to the module objects. A valve system consisting of a bus coupler and a module with input
data thus has three input objects. A valve system consisting of a bus coupler and a module without
input data has two input objects.
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.
