Aguas de Portugal (AdP) business group operates in the environent sector in Portugal and its mission focus on achieving the portuguese national objectives in the water supply and sewage sanitation and treatment as well as the valuation of waste.

In the water supply and sewage sanitation, the operations team of Aguas de Portugal works on an urban water cycle, involving capture, treatement, storage, supply and collection of urban and industrial sewage. It also includes its treatment and provision, involving recycling and reutilization.

CHALLENGE

agua

The water sector, as other industrial sectors, is under a lot of pressure as far as investments and exploitation costs go. This is one AdP’s main concerns: To have an efficient predictive maintenance plan that allows them to make informed decisions when faults and alarms are detected in certain field control points, hence reducing its maintenance costs. A remote management SCADA system is required in order to acquire real time field information enabling AdP access to historical and current data on demand to inform their decisions.

However, one of the typical features of water installations is its de-centralized architecture. Hence, one of its key challenges in this sector is the ability to remote monitor and control in real time. As remote management systems continue to grow in complexity, communications devices utilised in these architectures are required to be very robust and versatile.

DNP3 (Distributed Network Protocol, version 3) is the remote metering industrial protocol adopted by AdP in the communications between the Omron PLCs installed in its distributed plats, and its SCADA systems managing its remote management applications.

OBJECTIVES

To access

measurement and management information in real time.

To translate

OMRON proprietary metering protocols into standard  SCADA protocols.

To reduce

management costs as well as the need to renovate ALL current devices.

SOLUCIÓN

El Gateway GW-500 DNP3 ha permitido la supervisión remota y la telemetría DNP3/SCADA de PLC’s Omron, guardando compatibilidad con las diferentes series. Se han cubierto necesidades críticas en sus aplicaciones de telecontrol:

  • Dos configuraciones diferentes de alimentación: entrada extendida de 9 a 36 VDC y rango universal y extendido que va de los 30 a 400 VDC y 36 a 265 VAC
  • Alta seguridad en las comunicaciones incluyendo salvaguarda de datos en flash ante corte de alimentación
  • Envío de mensajes y reporting de eventos no solicitados
  • Almacenamiento de históricos en local
  • Reporting basado en cambios de eventos
  • Capacidad de trabajar como protocolo serie o a través de TCP/UDP con servicios de red
  • Dialoga los protocolos Omron Host Link, FINS Serie y FINS/TCP Client, que proporcionan conectividad con autómatas Omron mediante interfaces serie y Ethernet
  • Sincronización horaria
  • Operaciones de polling por eventos y reporte por excepción
  • Programación y configuración remota y carga y descarga de ficheros XML
  • Gestión de eventos time-stamp (con sincronización de fecha y hora)
