5 Functional Mechanisms of this Application
5.2 Parameter access functionality
SINAMICS G120 DP at S7-1200

Table 5-3: Interface assignment of FB “Parameter”
Decisive hardware identifier for
reading/writing parameters from/to a
DP standard slave / PROFINET IO
device.
When selecting the frame type in the
properties of the SINAMICS drive in
the TIA Portal, STEP 7 creates a
system constant which corresponds
to this identifier. Enter this system
constant here. It is symbolically
displayed to you in the dropdown list
when entering the parameters.
The transmission is started with a
rising edge at START.
False: Read ramp-up/ramp-down
time
True: Write ramp-up/down time
Default ramp-down time [s]
Ramp-up time [s] read by the
SINAMICS drive.
In the case of a send/receive error,
999999.9 is entered.
Ramp-down time [s] read by the
SINAMICS drive.
In the case of a send/receive error,
999999.9 is entered.
Job completed without error
The bit is pending until START is set
to 0 again.
The bit is set if an error ID was sent in
the drive response. Analyze the DB
103 “answer_from_drive”.
The bit is pending until START is set
to 0 again.
The bit is set if one of the instructions
WRREC or RDREC detects an error.
Further evaluation through static data
in the respective instance DB.

The bit is pending until START is set
to 0 again.
WR_ERROR = true → Error in instruction WRREC → Evaluation through WR_STATUS
3
RD_ERROR = true → Error in instruction RDREC → Evaluation through RD_STATUS

The tags WR_STATUS and RD_STATUS correspond to the output parameter
3
Status der instructions WRREC und RDREC. For more information, please refer to the STEP 7
