In fact me is working on a project, which consist of heating water through solar panels and to be stored in a hot water tank at about 65 c , there is a cold water tank as well. the problem is that i got to mix water @ a temperature of 40 c in a 1 metre cube mixing tank. this process should be automated.
I know that i should use a PID block in my program, the problem is that i do not know much about PID block, can say i dont know anything...
I have read the help in simatic, but its not enough for me to sort this out...
I would appreciate help indeed...
Thanks......
the plc being used is siemens S7 300...
The control output will be the poump itself.. by using an inverter..
my feedback will be temperature and level...
If there is some way out.. pls let me kno..
if some1 has another solution other than using a PID, will be appreciated as well..
Thanks....
