First defined in: FKiSS2.1
If the
fix value
for the object specified by
target is zero, the
ifnotfixed
action sets the timer for an alarm. If a timer for that alarm is already
counting down, the new delay time will replace it, resetting the alarm's
timer.
Setting delay to zero will cancel the timer for that alarm,
preventing the alarm from being activated.
target
In FKiSS2.1 to FKiSS3, target must be an object number.
In FKiSS4, target may be an object number or a
variable representing an object number.
alarm ID
In FKiSS2.1, alarm ID must be an alarm ID number.
In FKiSS3, alarm ID may be an alarm ID number or a variable representing an alarm ID number.
In FKiSS4, alarm ID may also be a symbolic name representing
an alarm or a variable representing an alarm ID number.
delay
In FKiSS2.1,
delay must be a number representing the delay
time in
milliseconds.
In FKiSS3,
delay may also be a variable representing the delay
time in
milliseconds.
Example:
;@ ifnotfixed(#5, 10, 1000) ; If the fixed value for object 5 is zero, set alarm 10 to 1000 milliseconds.
;@ ifnotfixed(VarObj, MyAlarm, VarDelay) ; If the fixed value for object identified by VarObj is zero, set alarm MyAlarm to VarDelay milliseconds.
