PLC Advanced Libraries
Analog signal processing:
Block | Description |
---|---|
Average / AverageL | Calculate the average of signal samples |
Integral | Calculate the integral of a signal |
Derivate | Derive a signal |
PID | PID"Proportional-Integral-Derivative" A PID controller is a generic control-loop feedback mechanism widely used in industrial control systems. An "error" occurs when an event or a disturbance triggers off a change in the process variable. A PID controller attempts to correct the error between a measured process variable and a desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly loop |

CurveLin | Linear interpolation on a curve |
SurfLin | Linear interpolation on a surface |
Alarm management:
Block | Description |
---|---|
Lim_Alrm | Low / High level detection |
