Which mode do I have to adjust at the diagnostics repeater, in
order to call the organization block OB82?
If the diagnostics Repeater is run with DPV1 mode at a S7 CPU, the
DP alarm mode of the repeater has nevertheless to be set to DPVO in
STEP 7. The diagnostics alarm OB (OB82) will then be called
continously in the S7-CPU.
In the register "Parameter assignment" in the object properties
of the diagnostics repeater, the "DP-alarm mode" can be set.
Choosing the DPV1 mode, the diagnostics alarm OB (OB82) will
not be called in case of diagnostics occurences in the S7
controller. Therefore it is recommended to keep the pre-adjustment
Further notes about the configuration can be found in chapter 6
"Commissioning" of the manual "SIMATIC diagnostics repeater for
PROFIBUS-DP" under entry-ID: 7915183.
