when I used pid controller block from simulink and clicked "tune", the errors says "too many input arguments". The plant was just integrator and negative unit feedback with step input. can you explain?

PID Tuner works only with Single Input Single Output loops. Is the error signal feeding into PID Controller block a scalar or a vector?
