Item
Instructions With the TON instruction, multiple cycles are
that last required from the start of instruction execution
multiple to the end and the instruction is reset when the
task periods power flow is FALSE. Therefore, you need to
declare only one instance to both execute the
instruction and reset it.
Func- Add a circle to indicate NOT at the intersection
tion/func- of the BOOL argument and the function/function

You must declare two instances, one for
execution and one to reset, as shown below.
IF (start = TRUE) THEN
TON_instance(In:=TRUE, omitted);
// Start timer.
ELSE
TON_instance(In:=FALSE, omitted);
// Reset timer.
END_IF;
Add a NOT operator to the argument.
* You can add NOT operators to any BOOL
variable, not just arguments.
