andris_81 Posts: 6 Rating: (0)	Hi, I need help. I am using VIPA 313C and VIPA TD03. The task is to heating bricks for 56 hours(increasing every 2 hours by some degries). And there are 8 types of bricks. To increase temperature we need to open hot air flap a little bit. I am using PID control and its working. For choosing any of 8 programm I using a TD03 function buttons. The problem is: how change setpoint every 2 hours. Maybe someone can help me. Thank You

If yes, you should use SIEMENS products first. If no, you have to ask VIPA technical support/ forum/.... But I do not think that you will found any of them! Bye

But since you are using simens software perhaps this may be help you. You may use real time clock or pulse counter using adding function. For example 3600s is one hour so if you use one-second pulse you can compare it on 7200 for two hours and move your set point. Of course there are many solutions this just a one. Next time use siemes controllers then you will not be in trebles as this. Thanks and best regards.
