ON
ON Command (On Event) syntax - ONn, GTx, ONn, GSx, ONn,0
Units: n/a
Range: n/a
Default: n/a
The ON command allows the user to define conditional program execution based
on the occurrence of a certain event.When the programmable event occurs,the
current program and move are interrupted and program execution begins at the
predefined interrupt program.The inter rupt program can be defined as a GT or a
GS.Defining the interrupt as a GS allows program execution to return to the exact
point in the original program where the interrupt occurred.The ON command cur-
rently supports EOT as an e vent conditional.
The syntax for defining an e vent and interrupt program number and type is
ONn,GTx or ONn,GSx where n is the event type and x is the interrupt program
number or name:
n: L On End of Travel Limit
The syntax for clearing a pr eviously defined event conditional is ONn,0 where n is
the event type as listed above and 0 (zero) is the clear event designator.
Once an ON e vent has been defined,it is active in all user programs and need not
be redefined unless the user wishes to change the interrupt program type, number
or name,or clear the event condition.
Example: Using ON to handle an EOT event
