Hi,

Is there a way I can fire a GPI via rosstalk when I take a scene?

The scenario is:

I want to trigger an application I made to automate a task when I specific scene in xpression is taken.

You can use a script in OnOnline to trigger a physical GPI on the Ross turnkey hardware.

This script for example:

`

dim gpiboard as xpGPIBoard

engine.GetGPIBoard(0, gpiboard)

gpiboard.SetOutputPinState(1, True)

`

If you want to send a RossTalk command instead, that can be done, but only in version 5.9 (only available to beta customers right now).

Hi Brian, thanks!

I actually am using Xpression 5.9. I was planning on using RossTalk for it so I could trigger a listen server I setup in Python.

#XPression

Ok if you have 5.9, then there is a function in the xpGPIBoard object called SendMessage.

You will want to configure the RossTalk driver in XPression to connect to your remote listening server

`gpiboard.SendMessage("some data to send")`

#XPression

So what you are saying is that from Xpression 5.9 you can actually send some data via RossTalk to/from Xpression?

Hi Brian,

So I've finally had time to mess with the Rosstalk GPI triggering in xpression, I just have a question.

I got it to work, it fires a message to my TCP server, but for some reason every few seconds I get a message from Xpression with the content of 'noop'. Do you know why this happens? Is this just a check to see if the server is still listening or something else?

#XPression

It's just a message to check if the socket is still connected. You can ignore it, there is no need to respond to it.
