STL编程语言中脉冲定时器
来源:艾特贸易2017-06-05
简介启动一个脉冲定时器的完整的 STL 程序如下: A Enable_input; FR Timer t; A Start_input; L Duration; SI Timer; A Reset_input; R Timer; L Timer; T Binary_time_value; LD Timer; T BCD_time_value; A Timer; = Timer_status; 采用 S
启动一个脉冲定时器的完整的STL程序如下:
A Enable_input;
FR Timer t;
A Start_input;
L Duration;
SI Timer;
A Reset_input;
R Timer;
L Timer;
T Binary_time_value;
LD Timer;
T BCD_time_value;
A Timer;
= Timer_status;
采用SCL,调用脉冲定时器编程如下:
BCD_time_value:=S_PULSE (
T_NO:=Timer,
S : = Start_input,
TV: =Duration.
R: = Reset_input,
Q : = Timer_status,
BI : =Binary_time_value),
