I am very new in PID as well as in simatic.I have a project where i have to use PID loop.
The objective is to maintain the temp. of a tank.The tank has to reach to a temp. of 155 C within 14 minutes in manner that the graph between time & temp. should be linear. The highest temp. to be maintain for next 90 minutes.
There is a valve from where hot steam is coming to maintain the temp & as well as the pressure.The valve has to be open & close to maintain the temp. according to PID loop.
I have to use fb 41,fb 42 & call that in ob 35
prefer me some manual/pdf
PLZ HELP!!!
