Ethercat 3rd Party Device Profile XML File not complete

Question

Hi all,
I'm trying to use a Schneider LXM32 servo drive coupled to a NI cRIO 9074 Ethercat master.
The problem is that my LabVIEW project is not showing me the full device profile.
There are 4 available PDO for this device :
1) Cyclic Synchronous Position
2) Cyclic Synchronous Velocity
3) Cyclic Synchronous Torque
4) Free switching beetween 1) 2) or 3)
BUT, I only see the firts PDO parameters after importing the xml file. If I open the xml file manually, I see that all the PDO are available.
The xml file is available in this post.
Of course, I need to operate in the 4) mode, not the 1)
Help me, please....

Answer 1

Hi,
Thank you for your answer.
I successfully modified the XML file of my Schneider drive :
Now I have a lot of others problems (I have made a request on NI France, I supposed you are the one who phoned me today).
1) The XML file of my LTi DRiVE (another drive of the test bench) is done like this (see attachment):
1) I can't move the Sm tag because it's already everywhere
2) I don't understand why 4 devices are exposed.
Additionnaly, see below the LabVIEW project with this device :
3) The I/O exposed for the 2 Devices (Schneider and Lti) are shared variables. But I want to poll these I/Os every 125µs. The scan engine can run at 1 ms. So, if a put a "percentage of each scan period" to 1% (the default value is 40%), will I be able to poll every 10 µs ?
In this example :
https://decibel.ni.com/content/docs/DOC-11191
The scan period is 4 ms at the best, so with 40% of each scan period, it represents 1.6 ms.... am I correct ?
4) Is it necessay to use NI SoftMotion (https://decibel.ni.com/content/docs/DOC-11191) to get/set data to a motor drive ? Is it much more easy with NI SoftMotion ?
Thanks,
