- Primary Area type SCADA supervision, composed by two servers
- Secondary/ Tertiary/Quaternary Area and four Operator Station (OS).
- RCC Precooling e Mixing Plant Area The SCADA system is distributed in three control
cabins (CR1, CR2 and CR3), with an Operator Station
(OS) for each Operator Control cabin, in order to give
the possibility to the operator to have a complete
control of its area of competence.
In case of need or unavailability of one of the Operator
Stations, the plant could be managed by the other OS
in the other Operator Control cabins.
A fourth OS station is placed in offices located in a
remote area and allows the personnel to supervise all
plant’s areas.
