invertek optidrive P2 -s7-1500

[mel_w]

Hi
I have a s7-1500 with an invertek drive on profinet the drive runs O.k on profinet but IO only has 4 words in and out all fixed
I need to be able to set parameters from the PLC /HMi
the manual advanced guide says

"Access to drive parameters via Profinet uses the Record Data Read / Write service of API0. The table gives the API, Slot, Sub Slot, and Index for
each parameter"

0, 0, 1, 0067h is given for acceleration ramp time (API, Slot, Sub Slot, Index)
0, 0, 1, 0068h for deceleration ramp
Has anyone any idea how I can access the parameters using the PLC to set
the Ramp times etc. ( suspect using RDREC and WRREC)

Regards
Mel
