Dennis - thanks for taking an interest. There are five vi's and sub-vi's in attached zip file as downloaded from NI.
FYI - I am an enthusiastic amateur who is trying to get across Labview for a home automation / security panel I have built. Works fine in VB but I'm trying to make it look nice with panels and charting. Working here in Riyadh, I have plenty of time to mess around. - regards Richard
