Hi all,
I have a PXIe system, with PXIe-8135 as the controller. The second Ethernet port is set as an EtherCAT port. I'm using EtherCAT to control and monitor a series of third-party servo motors, via their controller. Everything works okay except for one issue that I have no idea how to resolve... Which is, every time my PXI system resets, I need to power-cycle the driver. Else, I couldn't communicate properly with controllers. I've contacted the third-party motion vendor and they said that the problem lies in the synchronization between the PXIe and the controller - that every time PXI restarts, the synchronization is off and thus, there are some critical functions that I will not be able to perform. My questions are:
1. Is this claim true? I thought after the PXIe restarts, the communication resets itself and so will the communication/synchronization mechanism.
2. If the above claim is true, is there a way for me to reset the communication so that I do not need to power-cycle the controllers? I've tried down to changing the online device state and scan engine mode but to no avail.
3. Is there a proper shutdown procedure for EtherCAT, from LabVIEW's stand point? I suspect that maybe my shutdown procedure before restarting the PXIe wasn't correct and that leads to this issue.
That's all I have for now. Thanks in advance.
