Trio one - access the preview channel

[adishin]

I am using a Trio One box (engine and preview on the same hardware), but I would like to communicate with my preview channel, not by using the MSE preview channel, but through Trio commands. Specifically, I am now looking for a way to refresh the animation in the PVW (e.g., frame back and forward) without affecting the program.

Normally, one can use a hostname/IP in the Viz environment, but here the result will be the same. Does anyone have a workaround for this, or is the only solution to ensure that the channels are properly configured in MSE and then use the command "send_command to channel preview"?

you can get the previewchannel name by
TrioCmd("channelcontrol:get_preview_channel")

sending the commands:
TrioCmd("trio:send_vizcmd_to_channel channelName command")

thanks
but in some of our extrnal sets no instance is defined as preview as far as I know, so that won't work
