How to get all Powerflex 700 variables using COMM-E card in compact logix?

[rollex]

I have a comm-e card installed in a powerflex 700 and I can view all parameters within studio 5000 (compactlogix) no problem but how do I access them within the PLC program?

When I add the powerflex drive I only get a limited number of variables:

Ready
Running
Alarm
Faulted
Feedback

How do I access the other 200 variables via the PLC program? I see I can map 4 datalinks but this seems clumsy, if studio 5000 can view and access all the parameters surely the PLC can as well?

Do you really need all of them? You could also do explicit messaging.

I don't need them all, but I'm just curious why it isn't simple to get them all.

Could you point me in the direction of how I can get more than the 4 datalinks should I require them? Is direct messaging how it is done?

It's probably just to keep everything communicating briskly. Yes explicit messaging you can find info in the 20commE manual

It seems I get 8 variables if they are all 16 bit so the datalinks will do for now.
