OK! here is the start of my program and i'm not at the walking stage yet with programming i'm bum shuffling at the moment. So i have attached the beginning of this program so what i'm trying to achieve is the following: 1 turn on fans-timed for 1 minute 2 once timer has elapsed then start ignition sequence (once ignition sequence is completed i will get a closed 24v signal back from the ignition sequence) 3 signal from Ignition sequence then starts the 3rd stage heating a timer will run for 1 minute. i'm there with that as far as i can see (now here is the part where i'm well in over my head) once the 3rd stage heating has cut in i would like the PLC to control the heating by allowing the burner to raise the oven to say 180 deg then switch off the 3rd stage burner until the temp drops by 5 deg then back on off on and so forth,,,, once the burner has reached 150 deg i only want a burn time of 12 minutes after that i want the burner to shut down and that is by removing the signal to Q2 and once the oven has reached 60 deg it can then shut the fans down. We run the oven like this however it is manually operated with a sounder to tell the operator to start the shut down procedure. I appreciate any help or guidance in achieving this.
