Applications

The SP350 series PLCs are designed with power conservation in mind. They’re a natural choice for applications that require low power operation in tandem with a varied mix of analog and digital I/O as well as multiple communication ports. Coupled with real-time communications using industry-standard Modbus and DNP protocols, the controllers integrate easily with Weatherford’s operations management software and Vision series of operator interface terminals, as well as a wide range of third party SCADA software, MMIs, DCS systems, intelligent instrumentation and remote I/O control applications. Flexible controllers that can be used in both Modbus master and slave configurations, the PLCs support report-by-exception, store and forward messaging and can also make the most of DNP’s advanced protocol functionality, including maintenance polling, unsolicited messaging and data-backfilling. The SP350 series flow computer furnishes two or four run custody transfer options. In solar panel-powered applications the PLCs offer further cost reduction by allowing smaller solar panels and batteries to be used. The integrated DC/DC converter and overall small footprint also enables the use of compact mounting enclosures for those applications where space is at a premium. Similar in manufacture to all Weatherford electronic flow measurement (EFM) products, the PLCs have conformal coating, gold-plated machined sockets and zinc-plated steel system components. Regardless of the specific need, the controllers can provide reliable and compact stand-alone performance in the hazardous environments so often found in SCADA applications.
