Using data from DriveExplorer in FactoryTalk

I am working on creating a HMI in FactoryTalk View which will display data from a PowerFlex VFD on a screen. THe problem is, some data is not attainable through the drive itself, but rather needs to be viewed through DriveExplorer (ie output current and BUS VDC). Does anybody know how to link the data recieved through DriveExplorer to FactoryTalk view so they can be viewed in a HMI. Any help is much appreciated.
 
I don't think you can do that. You would have to use some other intermediary device such as a PLC to get data from drive to HMI. Is a PLC controlling these drives? What type of Comms (CNet,DNet,ENet)?
 
We are using Ethernet/IP to the drive. We are also using a controlLogix 1500 PLC to communicate with the drive. We can access various tags of the drive through RSLogix5000, but many of these parameters from DriveExplorer I can't seem to access.
In DE, you can create custom views and save them as cvf files. Wasn't 100% what I could do with those files.
 
When we have used Ethernet I/P from a ControlLogix processor (not sure what a 1500 in ControlLogix is) to drives the standard connection has only a few items of information in each direction dealing with control bits and reference frequency.

To get any other information from the drives required specific messages (MSG). You will have to write into the PLC program to retrieve the desired information then view it in the PLC' memory using the HMI.
 
Ok, I see what you are saying. That is actually how I am viewing tags now, through RSLogix5000 over ethernet I/P (tags of the drive). For data such as bus voltage and output current I couldn't find it. What you mentioned above, is this retreivable in the drive, or does it have to be brought in through driveExplorer. If so, how? Thank you.

You will have to pore over the manual for the ethernet module on the drive to find out what is available for explicit messaging as it applies to controllogix...

Depending on which drives you are using,(I know it can be done with the PF70, PF700, and 1336 drives) you can set up DataLinks in the drive parameters and read these into the PLC.

Have a look at the DataLink input and output section of the drive manual. You will link parameter numbers to these links and can send or receive drive parameters to the drive.
