11.3.4
Adjustable status (condensed status)
Diagnostics messages are generated in the DIAGNOSTICS physical block parameter
depending on the diagnostics events in the device. At the same time, the statuses of three
PowerTags (FEEDBACK_VALUE, READBACK and POS_D) that are sent to the master by
the SIPART PS2 PA positioner are affected.
In the device, there is now an option to use diagnostics messages and predefined status
messages that are permanently associated with the triggering diagnostics events. The
condensed status must be deactivated for this purpose.
If the condensed status is activated, the diagnostics messages in a specific frame can be
allocated to a smaller number of collective diagnostics messages and selectable status
messages. This "routing" of diagnostics events is shown in the following picture.

NOTICE
Please note that the condensed status cannot be changed using the SIMATIC PDM when
the device is in a cyclic operation with a master class 1.
