RFLink - MONITORING MULTIPLE SITES FROM A CENTRAL LOCATION




Control Centres Monitor Data From Regions

RFLink for RealFlex allows a company to monitor and control multiple regional centres from one control centre. It provides an efficient, secure and flexible method of connecting multiple RealFlex Control Centre locations to a central location. Easy ConfigurationRegional SCADA systems can share some or all of their databases with each other. One region can also control a neighbouring region if required. Complete databases or just sections of a database can be shared between systems to allow monitoring, control, information/control tags and alarm acknowledgement to be done from either system. This allows one region to be monitored by a neighbouring region when for example a regional operator is unable to work.

Regional Centres Share Data

The system is very flexible in configuration and automatically creates and maintains databases. This can represent cost savings in administration and maintenance of large complex systems. Customer can configure system to allow/disallow controls, alarm acknowledgements etc. for the remote database. This allows the customer to configure the systems to suit their individual needs. Low Bandwidth Communications
Efficient use of communications bandwidth is achieved by passing only changes between the systems. All data changes are transferred immediately to insure even small fleeting changes are not lost and it also minimize bandwidth usage and allow large systems to be interconnected with maximum efficiency. RFLink uses using standard TCP/IP for communications on LAN’s, WAN’s, internet or PPP.

Handle Communication Outages

RFLink can buffer messages in the event of a communications failure, so that once the connection is re-established the events are transmitted to the server and no data is lost. Automatic Database Creation and Synchronization Remotely monitored database is automatically created in the local system to minimize setup and configuration time, and to guarantee integrity of the databases. Database structures are automatically synchronized by transferring changes on one database to the other databases, which means a large reduction in maintenance of the system.
