Why do I get an error when I try to switch the scan engine mode programatically?

[volleymar]

Hello,

I have a problem with my EtherCAT system.

The system contains:

a PXI-8840 RT

2 Position sensors with EtherCAT

and 8 Inverters with EtherCAT (with Softmotion plugin and xml file)

I'm using LabVIEW 2015 with RT, FPGA and Softmotion modul.

At the beginning of my code I switch the scan engine mode to configuration mode and afterwards to active mode programmatically. This works well when I start my code with LabVIEW, but I receive an error when I use a startup application. The error code is -2132869095 (The deployment connection has timed out). I have tried this also with a code just containing the VIs for switching the scan engine mode and nothing else. With this I receive the same error.

The problem occurs when one or more inverters are in the project.

Has anyone an idea what I have to do to avoid this error?

Thank you.

Dear m.kroschk@eaat.de,

this is really a very strange behavior but I found a comparable issue in our internal database which was resolved by reformatting & reinstalling software to the RT-System.

So first of all I would ask you to try reformatting & reinstalling software your PXI-Target.

If the Error still appear, please Zip and post your minimum project for reproduction which I could test here to reproduce the issue on my system.

Kind Regards,

Dear SG3,

thank you for your reply. Reformatting and reinstalling the software don't fix the error. But I found two articels, which may help me:

I will try this and give you an information.

Thank you

Hello,

the two articels mentioned in my last post have fixed the problem. I have to follow this exact sequence and I have to wait until the scan engine is running.

Now, my startup application is running.
