Application ‘5’: PID
A simple application using a Proportional-Integral-Derivative 3-term controller. The setpoint is taken from
AIN1, with feedback signal from the process on AIN2. The scale and offset features of the analogue input
blocks may be used to correctly scale these signals. The difference between these two signals is taken as
the PID error. The output of the PID block is then used as the drive setpoint.
Configuration Setup:
RL1A
110-230Vac (or 24Vdc) voltage supply
