I/O system links radiation monitors to Scada
Omniflex has been providing BNFL and AEA with cost effective radiological monitoring systems.
"There is no infrastructure cost to consider as you have with in house radio based systems and you can extend your monitoring country wide - in fact it is possible to use the technology outside the countries borders too".
"A simple SIM card purchase with suitable GSM provider package is all that is required".
The Omniflex OPC server and Maxiflex outstations integrate to form an easy to use front end for Scada monitoring systems.
Reporting by exception (change of state) or on a time cycle basis the Maxiflex outstations are capable of interfacing to digital and analogue signals or even intelligent devices with serial protocols, such as Hart, Modbus or custom etc, the Maxiflex outstations can be used in telemetry mode or as controllers at the front end.
Setpoint parameter changes may be down loaded via the OPC server where and when required.
Forced outputs are also a feature of the system.
The OPC server provides the interface to any windows based application supporting the OPC standard, such as Scada systems or asset management systems.
A feature of the system is a call count monitoring system to keep a check on call traffic and provide early indication of over use.
This is especially important where change of state inputs (such as door alarms etc) on the outstation can trigger unnecessary calls if a fault develops on a door alarm.
The OPC server allows individual selection of digital input for change of state and these can be changed online without going out to the RTU. Request a free brochure from Omniflex (UK) ...
