Siemens SIROTEC Function Manual

Communication
11.1 Communication according to PROFIdrive
Drive functions
770 Function Manual, 11/2017, 6SL3097-4AB00-0BP5
The other diagnostics data (types) can be in any sequence. This is the reason that the
following diagnostics data include a header:
● Identifier-related diagnostics
● Status messages/module status
● Channel-related diagnostics
The diagnostic data type can be uniquely identified based on the header.
Note
The master must operate in the DPV1 mode.

In this context, the following values are decisive for diagnostics:
● Ext_Diag
– Group signal for diagnostics in the slave
– = 1, if at least 1 alarm is active
● Ext_Diag_Overflow
Display, diagnostics overflow in the slave (for more than 240 bytes)
