Custom Notify Messages..help please

[waverly]

In reading the Galil plugin pdf, I notice that a Galil command can be sent by Mach when set up in the "Custom Notify" tab. I do not understand though what the message ID is.  How is this used? I sincerely appreciate anyone helping me understand this.

Persistence (I mean many hours) pays off......at the Config, Plugin Configuration, Galil, Custom Notify tab I enabled an entry, entered a  message ID of 3000 and entered a command of SP1234. Then with the screen editor, I entered a VB script for a button press with the entry NotifyPlugins(3000).
The button press changes the speed for the x axis to 1234 counts/sec which I verify with Galil DMC SmartTerminal.
Cheers,

Thanks Waverly, I have been wondering how Custom Mesages worked for a long time.   Kit
