• PBGC/CTS/CCSOF. Supervision Software + Control Software + Data Acquisition Software +
• Data Management Software:
• SCADA System is composed of four Software Package with the following features:

The Supervision Software is in charge of monitoring in real time start and stop elements, unexpected conditions and

process evolution. In case of being necessary, it actuates on the system and notifies the user the incorrect operations.

The Control Software allows to manage multiple process and variables in real time either a manual way or automatic

way. Several type of algorithms of control such PID CONTROL are implemented depending on the field of study.

The Data Acquisition Software focus on measuring and processing signals from the process with very high accuracy

getting a synchronized and fast response of the system. A calibration system is part of this software to adjust the

sensor measurements.

The Data Management Software stores and represents, alarms, variables and process evolution in real time both in

a graphic format and in a numeric format such time charts or process diagram. Printable reports can be generated

or historian data can be loaded to study the experiments in detail.

The Software is open and flexible architecture that facilities to access different work levels both instructors and

students. It is supported by current Windows operating system and industrial standards. The graphical user interface is

intuitive and user- friendly.
