Hello,
We are facing a problem with the communication between NI Soft-motion Axis and a cRIO-
Hardware Details:
NI cRIO 9049- Runs on Linux
NI -Soft-motion- 9516
AKD Servo Drive P003 connected to C series 9516
Software Versions Installed:
LabVIEW 2017
NI Soft-motion 17.0.1
Application Background:
I'm controlling a Servo motor connected to the cRIO via LabVIEW. There's also an FPGA card in the cRIO because there are some c series cards running on FPGA.
1. I have already made sure every time i run the application, i reinitialize the hardware(vi with FPGA included) using the reinitialize example in Soft motion in LabVIEW examples.
2. I make sure when i add the Axis, the cRIO is in Configuration mode.
3. I start the FPGA application first in Configuration mode, and then change it to Active mode before starting my soft motion functionality.
Issue:
Every time i restart/power cycle the cRIO, the Axis looses communication with the cRIO i.e.
1. From the LabVIEW project, when i try deploying the soft-motion axis; it throws an error. Somehow if i manage to get past this, and launch the Interactive Test panel, there's a error thrown (77055).
2. Only way this works again is if i do the below steps
.In config mode - remove the axis from project,Check and undeploy missing items- Real time scan resource,add axis and set properties,Deploy Axis and then Start the FPGA vi
Change to active mode and then start the Interactive test panel
3. This is a problem because even if i remove the connection for a bit and connect the card again on the cRIO; the communication is lost and i have do step 2 again. Apparently this is the only way i can get it run again.
There needs to be a way to reset and connect seamlessly every time i power cycle. Could someone help me with this as its very critical and lot of time goes in fixing this.
Regards
Jay
