Example in FBD:

Example in ST:

TPInst(IN := VarBOOL1, PT:= T#5s);

VarBOOL2 :=TPInst.Q;

Provided by standard.lib.

The function block Timer On Delay implements a turn-on delay..

TON(IN, PT, Q, ET) means:

IN and PT are input variables of the BOOL and TIME types respectively. Q and ET are

output variables of the BOOL and TIME types respectively. If IN is FALSE, Q is FALSE and

As soon as IN becomes TRUE, the time will begin to be counted in milliseconds in ET

until its value is equal to PT. It will then remain constant.

Q is TRUE when IN is TRUE and ET is equal to PT. Otherwise it is FALSE.

Thus, Q has a rising edge when the time indicated in PT in milliseconds has run out.
