6.9.5 Channel-referred diagnostic data
The quantity of module-specific diagnostic information is dependent on the number of modules which contain
errors. Three bytes are needed for each error. The first byte describes the plug-in station number of the
module. The second byte indicates which channel had the error. The third byte describes the type of error.
