Communication110Parameter data transfer examplesThe following examples show how parameter data is transferredusing the DP-V1 mechanisms READ and WRITE.Note: Only the ìData unitî part of the SD2 telegram is presented inthe examples. See Figure 10 on page 102.Example 1a: Reading a drive parameter (array element)Drive parameters are addressed so that the drive parameter groupcorresponds to the parameter index (PNU), and the driveparameter number within the group corresponds to the subindex(IND). In the following example, a value is read from driveparameter number 12.04 (0C.04h).DP-V1 Write request (Read parameter value):DPheader5F 01 2F 0A 05 01 01 01 10 01 00 0C 00 04 DPtrailerDP-V1 Command PROFIdrive V3 Parameter ChannelSubindexParameter indexNumber of elementsAttribute (10h = Value)Number of parametersDrive object IDRequest ID (01h = Request Parameter)Request referenceData lengthIndexSlot numberFunction number
