I need to have the Accell and Decel parameter values sent to the drive from a MP 277 display. Any programming help would be greatly appreciated.

How are the datalinks setup on the 22-Comm-P? Are they16- or 32-bit wide? How many are there in your configuration, on the drive? Have you tried to setup the same number of datalinks in the HWConfig editor, on the Profibus slave? What data points of the drive are linked to the datalinks, and in what order? Do you have the software to interface with the drive, or will you have assistance from a Rockwell tech? Hope this helps, Daniel; Chartier

I haven't contacted Rockwell yet because I am not using their plc and they easily push back because of it. Iamnew to Step 7 and thought I might start here first. I also attached 22-comm-p profibus adapter chapter section for Parameter Access and a screen shot of my hardware configuration. I greatly appreciate your help.

It should give you more information than I could on the subject. You can download a pdf describing the application and a Step 7 project as an example. Use it to design your own program. However, to set parameters on the drive you will still need to use either a Powerflex keypad or something like DriveMonitor software; that was the point of myearlier questions. Hope this helps, Daniel Chartier
