Thanks everyone for your input, I am using persistent variables to retain the timer value after machine shutdown, and main task to be as low as possible for the seconds TON to be accurate.
Hi @ph0010421 and @Ton, Is it possible to program a stopwatch to measure a system running time when it is turn on, and pause when the system is turn off. I tried your examples when stopped, the elapsed time will then be calculated, but i need the time to be continuously counting. Warmest regards,
Hi @ph0010421, I tried the program the TimeTaken is calculated when stop is triggered. I want the TimeTaken to be continuously calculated and counting when a BOOL variable is true. I tried to program this way: Declaration: PROGRAM PLC_PRG VAR bStartStop: BOOL := FALSE; // Start/Stop button bReset: BOOL := FALSE; // Reset button bRunning: BOOL := FALSE; // Flag indicating whether the stopwatch is running tStartTime: TIME; // Variable to store the start time tElapsedTime: TIME; // Variable to store...
