Presentation
The CONT_CTL process control function block library supplied with Unity Pro 
software can be supplemented with optional specialized libraries so as to meet 
specic needs such as: 
b Predictive control 
b Fuzzy logic controller 
b HVAC
b Mass ow calculation
Fuzzy Control Library
This library is used in particular in the water treatment eld, for example for 
controlling chlorine levels in fresh water pools or controlling water levels in high-level 
reservoirs.
Flow Calculation Library
This library is used in the vertical Oil & Gas eld, for measuring the gas ow in 
compliance with the American Gas Association (AGA) standard. This version of the 
library includes the AGA3, AGA7 and AGA8 function blocks.
TeSys Library
This library provides function blocks for TeSys T and TeSys U starter-controllers for 
M340 and Premium platforms.
It includes function blocks and a help function for Unity Pro.
PCR Library for Unity Pro and Concept
This library is used for predictive control of process applications.
Originally developed for reactors, predictive control can be used in other industrial 
sectors.
Schneider Electric’s Companion Unity & Libraries team works in partnership with the 
French company Sherpa Engineering, who specialize in predictive control 
consultancy services.
Heating Ventilation & Air Conditioning Library
This library is used in the HVAC eld and deals with repetitive temperature control 
and humidity problems using ventilation equipment.
System Library for Unity Pro
This library offers functional blocks that are derived from Devices and Process 
Library but only has Unity Pro components (DFBs).
The Devices and Process Library supports several Schneider Electric devices 
including TeSys T and TeSys U starters-controllers, Modicon STB distributed inputs/
outputs, power meters, Altivar variable speed drives, Icla and Lexium integrated 
drives, SEPAM digital protection relays, various eldbus communications and other 
standard objects for motors.
There are approximately 100 objects in the library.
