APPLICATION 4: PID CONTROL
PID Control Application
A simple application using a Proportional-Integral-Derivative 3-term controller. By default the setpoint is taken from AIN1, with feedback signal
from the process on AIN2, scaling parameter 1939 swaps the routing of AIN1 & 2. 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.
