Hello All,
I am trying to modify tank level simulation example (in ni example finder under pid toolkit) in some way.....what i want do is whenever my output from pid i.e my manipulated variable (level of tank) exceeds the s.p; the Drain Valve (located at bottom of tank) should automatically change its state i.e if level rises above certain s.p valve should get "opened" and again it should change its state to "off" whenever level again comes down below s.p....The valve given is the customized boolean control...can it be accomplished by using reference or local variable?...Any help would be highly appreciated.
Best regards
