The contents of the "Device status" parameter from the physical block are reported along with
the information whether a status change (event received/event sent) has occurred.
Diagnostics as per PROFIBUS DP (DDLM_Slave_Diag)
The positioner delivers the diagnostics data in the following format:
Input (master view)
Starting address 0 Station_status_1
1 Station_status_2
2 Station_status_3 Standard DP - diagnostics
3 Diag_Master_Add
4 Ident_Number
5 Ident_Number
6 Header
7 Status_Type Status coding as per DP/V1
8 Slot_Number
9 Specifier
10 Diagnostics (0) Diagnostics object of the physical block
11 Diagnostics (1)
12 Diagnostics (2)
13 Diagnostics (3)
Specifier
The following specifiers are available:
1: Incoming event
2: Outgoing event
9.3.3 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.
