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
Cubicle
BUS.
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
Cubicle
BUS
module remains
in the list of modules present.
Figure 3-8
Outline diagnosis in the STEP7 HWConfig tool displays the diagnostic information
in text form. The modules recognized on the
Cubicle
BUS
and the last action on the
Cubicle
BUS
are indicated. Maintenance information is also available.
