I have to make on application involving analog and aPT100sensor. Can anyone help me with the shedule because it ain't working with me. This is the case: U haveone PT100 on analog input AI3. We wanna have 23°C ( in on 22,5°C and out on 23,5°C) from monday till friday in the morning between 7 and 8 and in the evening between 18 and 24, saturday and sunday from 9 int he morning till 24 in the evening. All the other times it needs to be 15°C (in on 14,5°C and out on 15,5°C). The 15°C and the23°C we become trough the analog input AI1 and AI2. In a warningtext we seethetime, date, the asked temperature and the measured temperature. When wepush I3 the temperature ask is swithed until the next time. Q2 shows us if the temperature ask is high(Q2=1) or low (Q2=0) When Q2 has chanced Q1(the heating) reacts 3seconds later Thanks everyone Attachmentheating.zip (937 Downloads) |

Hi!! In your text i understand that there is only 1 variable input PT100 and 2 fixed setpoints 15º and 23º C ( you dont need an analog input foryour setpoint ) you need a timer and you are not usingone in your program.. the "time simulator" you are using is a good idea.. i dont get the idea of Q2 or the 3 seconds delay.. please study the attachment... i hope it helps..
