Question:

Is there a way to do S Curve Profiling over Ethernet IP with the AKD ( i.e. from an Allen Bradley PLC ) based on there is a S-Curve option in the Motion Task tables. Is there a way to do this over EIP ( send the data table values, etc. )?

How can we take advantage of that feature using EIP as a fieldbus?

Answer:

The short answer is this cannot be done using the motion tasking drive over Ethernet IP or Modbus TCP for that matter.

The AKD_Move add-on-instruction ( AOI ) has no built-in S-Curve feature or capability.

In this application note, we’ll demonstrate the different command types supported by the AKD Ethernet IP drive. While the PLC screenshots demonstrate using an Allen Bradley PLC ( Compactlogix in this case ) the methods are not AB specific but part of the Ethernet IP protocol using the AKD Ethernet IP drive. We have not tested nor officially support other Ethernet IP masters beyond Micrologix1400 ( explicit only ), Compactlogix, and Contrologix.

What controllers does the AKD Ethernet IP drive support?

From the AKD RSLogix Communications Manual:

The only AB PLC/controllers we have experience with and support at the moment are:
Micrologix 1400 using the MSG block ( explicit messaging only )
Compactlogix and Contrologix ( also supports our AKD Add-On-Instructions library and cyclic data ).

Micrologix1100 and SLC500 5/05 are not compatible.
