i want to check the state of my signal

[university 756]

"i am using shift register to detect the change of state of my system. --- to detect when the temperature exist the limit, say 50 degree
therefore, i want to set a constraint that when the past value is below the limit, and the present value is over the limit, the loop is runned and value, time is recoreded.
My problem is that the system record the signal no matter the limit is reached or not

There are a number of things that need addressing in your code contact me directly and we can discuss them. To start off, in total, how many values are you reading from the fieldpoint?
