Parameter description​

Interface variableDeclarationData typeDescription
INVar_InputBOOLStart input bit
PTVar_InputTIMESet time input
QVar_OutputBOOLOutput bit
ETVar_OutputTIMEElapsed time

Corresponding syntax​

  • The input bit IN value is "TRUE", the timer starts, and at the same time, the Q value outputs "TRUE"
  • When the ET value is less than the PT value, the change in the IN value does not affect the output of the Q value and the timing of the ET value

Example​

  • LD example is shown in the following animation:

  • ST example is shown in the following code:
TP_TIME_1(
    IN:=IN1,
    PT:=T#1s,
    Q=>OUT,
    ET=>ET
);
IF OUT THEN
    iVar:=iVar+1;
    else
    iVar:=0;
END_IF;
