11.9 PROFIBUS DP
11.9.1 Setting the parameters for the shut–down behavior
If DP slaves respond to a shutdown in the PROFIBUS communication, e.g.
NCK reset during operation, with fault conditions, you can assign parameters for
a successive shutdown of the PROFIBUS communication using the following
machine data:
S MD11250 $MN_PROFIBUS_SHUTDOWN_TYPE (PROFIBUS shutdown
handling)
Note
The drives:
S SINAMICS S120
S SIMODRIVE 611U/UE, POSMO SI/CD/CA
can be operated in mode 0 (immediate shutdown).
11.9.2 Data descriptions (MD)
11250 PROFIBUS_SHUTDOWN_TYPE
MD number PROFIBUS shutdown handling
Default setting: 0 Min. input limit: 0 Maximum input limit: 2
Changes effective after RESET Protection level: 2/7 Units: –
Data type: UINT8 Applies from SW version: 2.2
Significance: Shut–down modes of PROFIBUS DP communication:
0 = PROFIBUS DP communication is shut down at the DP master end without any
warning.
1 = The PROFIBUS DP is put into status CLEAR for at least 20 cycles.
Then PROFIBUS DP communication is deactivated.
If it is not possible to put the PROFIBUS DP in status CLEAR, proceed as described
under 2.
Use this procedure with: SINUMERIK 840D with DP–Link module.
2 = Zero values are transmitted for at least 20 clock cycles for all DP slave drives
connected to PROFIBUS DP for the following frame data:
– Control word 1
– Control word 2
PROFIBUS DP communication is then shut down.
To be used for: SINUMERIK 840Di sl in conjunction with external drives.
