7.3.4 TONR_TIME

Function

TONR_TIME is called a time accumulator, which can accumulate the state 1 signal of the input signal IN

Parameter description

Interface variable	Declaration	Data type	Description
IN	Var_Input	BOOL	Start input bit
PT	Var_Input	TIME	Set time input
Q	Var_Output	BOOL	Output bit
ET	Var_Output	TIME	Elapsed time
R	Var_Output	BOOL	Reset

Corresponding syntax

• When the IN value changes from FALSE to TRUE, the timer starts
• When the ET value is less than the PT value and the IN value is TRUE, ET continues to count. When the IN value is FALSE, ET immediately stops timing and keeps
• When the ET value is equal to the PT value, the Q value outputs TRUE, ET stops timing and remains until IN becomes FALSE, and ET returns to 0
• At any time, when R is TRUE, the Q output value is FALSE, and the ET value stops immediately and returns to 0. When R changes from TRUE to FALSE, if IN is TRUE at this time, the timer starts

Don’t forget the definition

Function block usage requires global declaration of an instance

Example

• LD example is shown in the following animation:

• ST example is shown in the following code:

TONR_TIME_1(
    IN:=IN1,
    R:=RESET,
    PT:=T#2s,
    Q=>OUT,
    ET=>ET
);
IF OUT THEN
    iVar:=iVar+1;
    else
    iVar:=0;
END_IF;
