Mitsubishi Electric has optimised several Irish waste water treatment and purification plants in a matter of weeks.   Working with MAPS (Mitsubishi Adroit Process Suite), e-F@ctory alliance partner Adroit Technologies created customer-specific templates for use at the Irish waste water treatment and purification plants. After verification, the full commissioning of four small to medium-sized purification plants was carried out in less than a week.

Improved data security

Modern communication solutions, remote control concepts and flexible data management mean that the plant operators are now able to visualise the status of all the parts of the plant from a central location at any time. All the data required are archived automatically, which has meant dispensing with local data collection costs as plant values are checked remotely.

In the process, Windows Security ensures that only authorised persons are able to access the system by managing users and groups. MAPS accesses these user structures and manages user rights within the application. In addition, MAPS uses the user profiles stored in Windows Security to call up and save settings within the application. Individual configuration changes are stored with user access profile.

FASTER ALARM RESPONSE TIMES

Local Mitsubishi Electric GOT Series operator terminals provide monitoring and manual control of the individual stations.  As plant-wide information is immediately accessible, the engineers can display a system. The GOTs provide powerful diagnostic functions to ensure rapid fault detection, leading to shorter down times.

Alarms are displayed immediately within the control room via the centralised alarm system. In the event of a problem, system sends a text message to the members of the service team via standard mobile data terminals. The transmission of level data or the current status of pumps and sensors by SMS can also be requested. This non-location-dependent access makes workers more flexible and avoids the need to purchase additional hardware.

IMPROVED PLANT INFORMATON

The Adroit SCADA Intelligence Suite (ASI) collates plant wide information.  The database is searched at regular intervals for availability, delivery rates, energy consumption and other user-specific data, and stored for each pump.

Once configured, this information will be periodically stored in the so-called data warehouse.  From there it can then be quickly and clearly displayed in an Excel-based report enabling a studying the efficiency of the pumps.

Unlike the old system, information required by the Environmental Protection Agency is now compiled and formatted automatically by MAPS business intelligence system (ASI).

COST REDUCTIONS

Remote access via MAPS and the Business Intelligence System (ASI) has increased efficiency and security whilst improving remote maintenance, servicing, and automated continuous data collection and preparation. These improvements have contributed towards the reduction of ongoing operating costs.
