Hi, I am having some troubles with the values that are returned by my formula node. I was hoping someone could glance at my code and offer some assistance. Note the VI will not run b/c it requires the FP module and hardware. In my attached VI, I have the following in the ROOM1 - Cool Down Formula node: int GTMP; int STEP; float32 CGTMP; float32 CGTMPLO; float32 CGTMPHI; int HTM; int ETM; float32 TTMPLO; float32 TTMPHI; HTM = 60/ROC; GTMP=STTMP - TTMP; TTMPHI = TTMP + 1; TTMPLO = TTMP - 1; if (STEP == 0) {CGTMP = STTMP - 1; STEP = 1;} CGTMPLO = CGTMP - 1; CGTMPHI = CGTMP + 1; if (STEP == 1) { ETM++;} if (HTM == ETM/2) { ETM = 0; CGTMP = CGTMP - 1; } if (CTTMP < CGTMPLO) { HTROn = 1; } if (CTTMP > CGTMPHI) { HTROn = 0; } if (CTTMP > CGTMPLO && CTTMP < CGTMPHI) { HTROn =0; } if (CTTMP > TTMPLO && CTTMP < TTMPHI) { TTReach = 1; HTROn = 0; } The problems are that if I want to do this: CGTMPLO = CGTMP - 0.5; CGTMPHI = CGTMP + 0.5; I still get a whole number and not a decimal. I thought since my variables are defined as floating point I would have no problem but I was wrong. Also, line of code ETM++ does not incrment each time this code is executed. I tried to put in a conditional statement so I know that it would execute that line of code under certain conditions and the indicator does not note show that the ETM value has increased. Am I correct in assuming that each time this code is ran the variables displayed on the indicators should refresh? I understand that a lot of this could be re-written using LV but I am close to being done and am under some time constraints. If I can get my two problems fixed I would be good to go. Thanks for the help.
