description
If the
input IN changes from TRUE to FALSE , it
is turned off after delaying the length of
time in the input PT . After the length of
the PT value, the Q value is set
to FALSE . The process time interval is
displayed on the output ET .

IL programming language
LD, FBD programming language
Function: The TON instruction is used to implement the delay on function. If the input
terminal IN is FALSE , the output terminal Q will immediately become FALSE; if the input
terminal IN changes from FALSE to TRUE , the output terminal Q will be delayed by a certain
time and then changed by FALSE. For TRUE , this delay time is the value of PT , and the ET end
records the time between the time when the IN changes to FALSE and the time when the Q end
changes to TRUE .
