Hello, I need to set a 1 second timer in a TSX 572623 plc with pl7 pro, the question is that using %s6 bit (1 second pulse) the timer is not exact enough, the program is 98 kb, not too big I think, I use the %s6 attaching to a positive pulse auxiliar mark in one section of the program and i use this mark %M in the rest of the program, but as i said, it is not quite exact, measuring the time displayed in a HMI connected to the plc, 40 seconds in the program (displayed in a HMI), it´s 47 seconds in a chronometer, it is not exact at all as I said, how can I solve this problem, can anyone help me? Thanks
