7.4.5.5 Example 2: write parameters (multi-parameter request)
Requirements
● The PROFIdrive controller has been commissioned and is fully operational.
● PROFIdrive communication between the controller and the device is operational.
● The controller can read and write data sets in conformance with PROFIdrive DPV1.
Task description
ON command and enable are to be set up via the input terminals of the CUD. A parameter
request is to be used to write the corresponding parameters as follows:
•
BI: p0840 = r53010.0
ON/OFF1
•
BI: p0852 = r53010.6
Enable operation
•
CI: p55050 = r52401
Fixed value 1 as current setpoint filter
•
p50401 = 80 %
Set fixed value 1 to 80
%
The request is to be handled using a request and response data block.

To establish BICO interconnections, the target parameters (p0840, p0852, p55050) are
transferred a reference to the source parameters (r53010.0, r53010.6, r52401):

r53010 2 (in the example,
DCP_CTRL)

Using drive object No. 63, a drive object can only be interconnected with itself. More detailed
information is provided in Chapter "BICO technology: Interconnecting signals (Page 164)".
