Hi all,
I need to communicate with a Parker ACR-9000 motion controller. They have an OCX and .NET wrapper that can be used to communicate with their ComACRsrvr.dll. My question is has anyone created any LabVIEW wrappers / drivers for this OCX that they are willing to share? Or have any experiences, good or bad using this kit?

Hi,
In our system the main motion control has been written using Parker software (ACR view) and the GUI has been written in LabVIEW. The two systems communicate / handshake by setting / reading the values from a shared memory block in the ACR-9000. So in LabVIEW I do little more than make a connection with the ACR and then read and write to this memory block.
In LabVIEW I’m using Automation open to open the following 2 controls:
BOXBRIDGELib.Icontrol
BOXBRIDGELib.Istatus
I poll 1200 values from the ACR and it seems quite efficient at doing that.
Personally I would prefer to use NI motion control hardware, I've had much better experiences using NI controllers rather than Parker.
Good luck.

Hi,
I use the IControl class for the “SetGlobal” and “SetFlag” methods. I also assumed that the MOTION TOOLBOX is of no use with the ACR9000.
