Solvaer Posted August 16, 2018 Report Share Posted August 16, 2018 Hello. im pretty new to unitronics plc's and im wondering if some guru's here would like to help me solve my problem. im struggling to figure out how to change a timer value depending on how full a tank of water is. the timer is suppose to be changeable. currently set at 3 minutes. The proces Tank 1: no features Tank 2: There is an preassure transmitter which mesuares the height of the water in the tank this level is used so that the tank 3 can pump water back to tank 1 without having tank 2 pumping in too much water to tank 3. there is also a pump which pumps water in to tank 3 Tank 3 Pumps water back to tank 1 (some water is drained out of the tank. There is only a level transmitter in tank 2. tank 1 and 3 does not have any way to measure the level. (not needed beacouse the water in tank 1 drains down to tank 2, and the water in tank 3 drains out of the tank aswell) What im trying to figure out: 0% full = 100% of 3 minutes 25% full = 75% of 3 minutes 50% full = 50% of 3 minutes 75% full = 25% of 3 minutes 100% = 5% of 3 minutes Im trying to load these values to the same timer. depending on which level tank 2 currently possesses . There is a simular program to the one im trying to make on the m90 plc. but we have upgraded to a samba 7 for this project. i will attach some pictures of how it has been done earlier. i did not find the system operand in visilogic. Keep in mind that im only 19 years old and dont have too many years of experience when it comes to programming Quote Link to comment Share on other sites More sharing options...
MVP 2022 Joe Tauser Posted August 17, 2018 MVP 2022 Report Share Posted August 17, 2018 This is much easier in a Vision system. There is a Store to Timer Preset function under the Store menu- Unitronics timers base value is 0.01 seconds, so your preset values must be scaled accordingly. The above picture shows three minutes, or 180.00 seconds. Joe T. Quote Link to comment Share on other sites More sharing options...
