Basic Features of Modern PID Controllers
Most modern PID controllers have the following features: Manual versus automatic mode Output tracking Setpoint tracking Alarm capabilities Process variable (PV) characterization and damping Setpoint limits Output limits PID tuning security Manual and Automatic Modes When the controller manually calculates the output values based on process variable (PV) and setpoint (SP) values overtime, it is…

Digital PID Controllers
Digital PID controllers have replaced most pneumatic and electronic analog controllers in industrial control applications. Digital PID controllers are preferred over the analog types because they employ microprocessors which can execute multiple functions at ago hence they bring with them many advantages in addition to their ability to network with PC workstations and other controllers…
