, the building includes several Compact FieldPoints in order to collect data
from the installation connected to the SCADA system developed with LabVIEW
by means of industrial Ethernet. On the other hand, the solar cooling installation
has its own acquisition system developed by SAUTER (
2013
), that can be accessed
by means of Object linking and embedding for Process Control (OPC), which is
a communication standard in the industrial processes control and supervision area.
Finally, to access the acquired data from outside the building, a connection through
Virtual Private Network (VPN) with a computer inside the private network of the
building can be established, and once inside it accesses the SCADA system that is
used via Ethernet.
Acquisition module
This module is responsible for communication with the data acquisition modules
(Compact FieldPoints) via industrial Ethernet. Hence, it performs data acquisi-
tion through connections to each one of the Compact FieldPoints which com-
pose the system, and then, these data, acquired from different sensors, are stored
in a database. Subsequently, through the use of an interface, these data are
sent to the supervision module. Some of the main characteristics of this mod-
ule are easy configuration of the channels and the addition of new sensors.
