Momentary Button in VB Script in RSView32?

imloggedin · Apr 1, 2009

Is their a function to send a momentary output to a tag? For writing analogs for example I use this...

Dim SP As Tag
Set SP = gTagDb.GetTag("SP\SETPOINT_SP")
SP.Value = TextBox1.Text

What about digitals though? I need to have a button on a VB form and send a momentary output.

Thanks.

Just set the value directly to true (or false, 1 or 0) in RSView, then in the target device (assuming a PLC here) reset it to the default state after you've processed it.

Otherwise, you have to start playing with setting up timers and such, which is probably not a good idea.

So theres no vb function to do a momentary?

Could you elaborate as to why you feel it is necessary to this rather than to use the standard features already available in RSView. When you enter an analog value (such as a setpoint) in RSView it is written once to the referenced tag in the PLC. With digitals you can set, reset, toggle, etc. Why would you need to write a VB script?

Im not sure what your asking but i already have a form made in VBA, im adding additional features to this form. RSTrendX would only work correctly in VBA not in RSView32 so thats what i did instead of fighting with it. Now i need to make a button to toggle a digital.

RSView 32 - Write to digital tag

Try this for the vba command you are looking for;

gCommand.Execute ("Set Tagname 1")

Of course your need to change Tagname to the name in your application tag database. If this does not work let me know and I will see if I can give you further help.
