Subject: Re: CSS-Boy : trigger not firing for $(pv_name) at runtime (FIXED)

Hi Kay

I took your advice and the 'disconnected' $(mdev) reported its value as null, therefore not connecting.

Although I do change my passed macro to a valid PV, somehow the initial $(mdev) shows null.

In my 'linking' OPI, I added a local pv value of 0 to my macro

$mdev = $loc://mdev(0)

and now it works fine.

Thanks for all your valuable help.

No idea.

Right-click on the running wheel widget, open "Show Macros" to see if the macro indeed receives the text "Disconnected", or if the macro has an erroneous PV name, so then the widget cannot connect to that bad PV and thus shows Disconnected.
