Veristand 2016 NI-XNET Signal Frame Configuration Page - Definition of Transmission Trigger "Trigger channel (not zero)"

marco.ferrari · ‎03-13-2025

Hello,

I'm working on a CAN-communication via a PXI and NI-XNET. In the Outgoing CAN frame specification in VeriStand, I can set a Transmission Trigger for every CAN frame.

Now my question is:

How is the Transmit Trigger "Trigger channel (not zero)" defined in detail?

In the help section "Signal Frame Configuration Page" I only get the following description:

Trigger channel (not zero)—Triggers when the Trigger channel value is not zero.

Now, does this mean the CAN frame is sent once at the positive edge of the channel, or is it sent continuously as long as the channel value is not zero?

I need the first option (send data once when triggered by the channel), but the above description in the help-file is a bit ambiguous to me. I also have VeriStand 2017 installed, but the options are exactly the same. I do not have the equippment to try this out on the hardware with a CAN-logger, and could't find any more detailled description online.

Thanks for your help!
