Touch Screen Monitor Program
I have a touch screen monitor (HMI) that I am tinkering with. It programs a series of tempurature controllers I have. I got it to talk to one controller but it doesn't pass on the info to 1 other controller I have attached for practice. Here is the code I have.
The HMI has a TAG section and all of my TAG's are associated correctly.
int range = 5;
while(State != 3)
if((Abs(PV1-ActiveSP) < range)&&(Abs(PV2-ActiveSP1) < range)) // wait until PV is with range
State = 1;
FinishTime = GetNow() + ActiveSoak;
if(GetNow() >= FinishTime)
State = 2;
if((SPs[RunningStep] == 0)&&(SPs1[RunningStep] == 0)&&
(Ramps[RunningStep] == 0)&&(Ramps1[RunningStep] == 0)&&
(Soaks[RunningStep] == 0)&&(Soaks1[RunningStep] == 0))
State = 3;
CTL = 0;
ActiveSP = 0;
State = 0;
ActiveSP = SPs[RunningStep];
ActiveRamp = Ramps[RunningStep];
ActiveSoak = Soaks[RunningStep];
ActiveSP1 = SPs1[RunningStep];
ActiveRR1 = Ramps1[RunningStep];
ActiveSoak1 = Soaks1[RunningStep];
This may be odd since it's not a OS specific problem.
Any help is appreciated. Just a warning, I will have many more questions I am sure. Plus if you can help with this I can direct you to the program software that is free with this HMI and you can view my Database completely.
