NetLinx Button Event:
LEVEL_EVENT [TEMP, 1]
{
IF (LEVEL.VALUE>= COOL_POINT)
{
ON[RELAY,FAN]
}
ELSE IF (LEVEL.VALUE <= HEAT_POINT)
{
OFF[RELAY,FAN]
}
}
LEVEL_VALUE is an embedded object value in the LEVEL_EVENT statement. If the event handler is
specified using an array for
DEV, CHANNEL, or a DEVCHAN array, GET_LAST can be used to determine
which index in the array caused the event to run.
Custom events
A custom event is generated by certain devices in response to query commands or unique device events.
For instance, G4 touch panels generate custom events in response to button query commands or mouse
clicks. An example channel event is shown below:
CUSTOM_EVENT[DEVICE,ADDRESS,EVENTID] or CUSTOM_EVENT[DEVCHAN,EVENTID]
{
}
The EVENTID is specific to each device. For instance, the EVENTID sent in response to a button text
query command for G4 touch panels is 1001. For more information on
EVENTID values and the values
of the custom event for each
EVENTID, see the programming section of the device manual with which
you are working.
The following table lists the information contained in Custom events:
