Let me know what is on your wish list!

Its very flexible and you can do a lot that you can't do with the RMC.
If you have a wish list like the one for the Red Lion I would love to see it. I bet most manufacturers that monitor this site would love to see constructive ideas like the one about making the Red Lion displays better. I know I would.
You should also know that the RMC150, the new stuff, isn't officially released yet and isn't done yet. CharlesM is one of the first to see a RMC150. We can make commands that do exactly what you want to if you just let us know. Have you looked at the time the CPU takes per loop? You can see we have plenty of time left to add the features you may need.
If the feature you want isn't there then tell us
Even negative feedback keeps us from oscillating
Now back to Rockwell vs Siemens motion control. I am biased toward the Rockwell motion control since we make the 1756-HYD02 and 1756-MO2AS for Rockwell.
The Rockwell motion control has motion blocks that allows one to easily move axes from ladder. It is also possible to coordinate many axes from the PLC but since the PLC does all the coordination one needs to add more processors as more motion modules are added. The back plane has a Sercos like interface where position are downloaded at fixed intervals and the motion modules do fine interpolation from point to point.
The M02AE,HYD02 and M02AS, and maybe more, share the same code and are different only in the inputs or feedback. This means that you can mix and match these modules and they will all work pretty much the same. If you know one module then you know the others. If you need to mix and match feed back then this is an important feature. I insisted on this. This is a feature that we have had on the RMC100 since the beginning and now on the RMC150. Previously, the SLC500 had many motion motion modules made by many different companies. We made the 1746-QS. The problem was tech support. Each SLC500 motion module was completely different. This is not the case with the Control Logix motion modules. This makes supporting the motion module much easier since there is a unified interface. It also makes it much easier for the end user because learning one module provides 97% of what you need to know to use the other modules. I know I am sounding like a Rockwell advertisement. Just know that our motion controllers work with either Siemens or Rockwell PLCs.
