How to implement alarm sound signals in web clients.
In order to be able to run the alarm on a web client depending on the alarms generated on the server, it is necessary to create a permanent link that will inform the client about the state of the alarms. The PmgButton
object or image (PmgCanvas
) placed in permanently opened panel (usualy Toolbar
) can be easily used for such purpose.
The procedure goes by following steps:
- On the "Variables
" tab of this object, create variable of the Integer
type named "nAlState3
- Then create the script marked as Example in the onRefresh
variable can be used also for changing the color of text, background, image, etc. The object can also be used as button for opening the alarm viewer. See Opening the viewer of the PmaAlarmGroup object
