ALARM ONLY TAGS (BOZZA)
------------------------------------------------------------------------------

An alarm only [tag] can only be used for its
[alarm] by the [alarm system]. An alarm only [tag]:
* Has to be [read only] also. * Must have a single
read-only [I/O hook]. No [code] or [animation] can
read or write the value of an alarm only [tag]. The
advantage of using alarm only [tags] is their low
cost for [licence] I/O tag count. Indeed an alarm
only [tag] count only an 1/8th of an I/O tag for
[licence] limitation. So an alarm
collecting/recording [JSup application] would be
very cheap, because every 8 alarm only [tags] only
one I/O tag is counted for [licence] I/O
limitation.
