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

File Name: HHMMSS.cxf File Submitter: ParaffinPower File Submitted: 08 Dec 2014 File Category: PLC Sample Code FB to provide a simple long timer with time remaining outputs. Time can be entered in HMS (or just mins for example). Time remaining is normalised to HMS though. Uses 2 other FBs. Create instances of HHMMSS as required. Click here to download this file

Hi I need to program my fatek fab Plc with the following : . I need to detect between a single long input or a repeated second pulse. The idea is to control a window blind with two outputs of the Plc and two inputs (one for up, from a up switch and another for down from the down switch). the blind should go up until I maintain the key pressed. But when I make a repeated two pulse on the key it should go up automatically during a certainly define time (enough to completely open the blind). The same for the down direction. I need help on that.
