PIDE RSLogix 5k doubt

Hi,

Right now I am trying to control the temperature of a furnace.

Is it possible to program a PIDE for getting to a certain temperature (Starting at 300ºC to 400ºC for example) BUT in a time of 5 hours and later with the same furnace and PIDE make the same operation but in a shorter or longer time.

Another example might help:

From 100ºC to 200ºC in 3 hours, later from the 200ºC to 400ºC in 7 hours... etc etc, is it possible with the same PIDE?

I dont know if I am explaining myself.

Thanks!

Use the system clock or a timer to gradually change the set-point in the PIDE block from min to max in x minutes.

My first idea was to create an equation of the process and then subtitute the x variable for getting the sp in certain time and then change the SP.

Seems a little complicated but possible. Im trying to find a better way to do it
