The idea is to record the up time of each process. I am using a CPU315F-2PN/DP. I tried using the SFB0 CTU IEC_TC counter. I started by using to timers which will reset each other. this way i get a bit turning ON every 1 hour. each timer is set to 30m. i then count this using the IEC counter. each count will represent 1 hour. The problem is that this counter only goes up to 32767. Is there another function that can be use to go up to 6 digits? Thanking you in advance for any help. Regards, Raymond..
