PLC Advanced Libraries

Below are the standard blocks that perform advanced operations.

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
Ramp	Ramp signal
Rand	Give a Random value modulo the input value
Lim_Alrm	Low / High level detection
Hyster, HysterAcc	Hysterisis calculation
SigPlay	Play an analog signal from a resource
SigScale	Get a point from a signal resource
CurveLin	Linear interpolation on a curve
SurfLin	Linear interpolation on a surface

Alarm management:

Block	Description
Lim_Alrm	Low / High level detection
Alarm_M	Alarm with manual reset
ALARM_A	Alarm with automatic reset

Data collections and serialization:

Block	Description
StackInt	Stack of integers
FIFO	"First in / first out" list
LIFO	"Last in / first out" stack
SerializeIn	Extract data from a binary frame.
SerializeOut	Write data to a binary frame.

Data Logging:

Block	Description
LogFileCSV	Log values of variables to a CSV file

Special operations:

Block	Description
GetSysInfo	Get system information
Printf	Trace messages
CycleStop	Sets the application in cycle stepping mode
FatalStop	Breaks the cycle and stop with fatal error
EnableEvents	Enable / disable produced events for binding
ApplyRecipeColumn	Apply the values of a column from a recipe file
VLID	Get the ID of an embedded list of variables
SigID	Get the ID of a signal resource

Communication:
