The method of requesting the slave diagnosis can be found in
the manual for the DP master.
If the device−related diagnosis is not treated, this results in a
stop of the PLC. The message can therefore be suppressed
(see section 4.2.2, Fig. 4/4).
Station status 1
With station status 1 bit 3 is especially of interest. If this bit is
set, it is sensible to evaluate the device−related diagnosis.
