Table
3-11
This table explains bytes 20 to 23 and 24 to 27 of the device-specific diagnosis of the WL. Bytes 20 to 23 indicate the module that is referenced for
diagnostic message 19.2 to 19.4 The bytes indicate all of the modules connected to the CubicleBUS.
The same applies to removing modules,
except here, modules that are to be
removed are not removed until the outgoing
diagnostic message has been deleted from
the list of modules present.
If a fault is reported on a module, the
CubicleBUS module remains in the list of
modules present.
Figure

Outline diagnosis in the STEP7 HWConfig tool displays the diagnostic information in text form.
The modules recognized on the CubicleBUS and the last action on the CubicleBUS are
indicated. Maintenance information is also available.
