The Step7 On-line Help Software
The Step7 online help software describes the SFC (DP NRM_DG).
Description
With SFC 13 „DPNRM_DG" (read diagnosis data of a DP slave),
you can read the current diagnostic data of a DP slave in the form
that is defined in EN 50 170 Volume 2, Profibus. After correct data
transmission, the read-in data is entered into the target area that is
defined by RECORD.
You can start the reading process by setting the REQ input
parameter to 1 when the SFC 13 is run.
Method
The reading process is performed in asynchronous mode, i.e. it can
be extended over several SFC calls. The state of the task is displayed
via the RET_VAL and BUSY output parameters.
