hi,friends i tried to study pid control using PLC for that purpose i have used rslogix 500 and select ML1400 as plc.after making the ladder logic.i have downloaded the program to rs emulate 500 and tried to simulate the control but i found that PID dosen't producing any control signal.i have tried different values for SP,PV..but still PID controller not producing any cv out put.At the same time i am able to produce produce CV out put by changing the mode to manual and by increasing %cv.
Is this mean that RSemulate is not able to provide the stimulation for PID controller.And For that we need Actual hardware?
i tried the same thing by using scaled and non scaled raw data for pv and sp but still PID not producing any cv Out put.
i have also change loop update time to several value but still no cv out put .
so can any body tell what i should do to solve the problem?
