The Yokogawa Cape Town team, based out of Tygervalley, is ready to serve the regional market with dedicated local sales, service and engineering resources. Yokogawa supports a significant installed base in the Western Cape comprising several flagship DCS installations based on Yokogawa’s Centum DCS and ProSafe RS safety platforms.
Yokogawa supports a wide range of control and instrumentation solutions including Distributed Control Systems (DCS,) Safety Systems (SIS,) PLC/SCADA, field instrumentation and analytical equipment, and a suite of software solutions supporting MIS/MES applications, advanced process control, terminal management systems, operator efficiency packages, asset management and many others. Yokogawa supports the entire plant life-cycle from conceptual/design phase, through detail design, project execution, and offers a comprehensive set of life-cycle support services and training.
Yokogawa has also announced that it had developed a multi-protocol wireless adaptor that enables wired field instruments or analytical sensors to be used as ISA100 Wireless devices, and will release models in May and July that support communications based on the HART and RS485 Modbus standards. To facilitate the introduction of field wireless systems in plants, Yokogawa plans to release additional models that will cover other standards.
Field wireless systems enable the field devices and the host-level monitoring, control, and other systems in a plant to communicate wirelessly with each other. They have numerous advantages such as allowing the placement of field instruments or analytical sensors in difficult to wire locations, eliminating the need for cables to connect devices, and costing less to install. In accordance with its “Wireless Anywhere” concept, Yokogawa seeks to promote the plant-wide use of field wireless systems by developing ISA100 Wireless devices such as this multi-protocol wireless adaptor.
When the multi-protocol wireless adaptor is mounted on a wired field instrument or analytical sensor, the instrument or sensor is able to function as an ISA100 wireless device. It may be used with any type of wired field instrument or analytical sensor commonly used in plants, including those used to monitor temperature, pressure, liquid level, or vibration, or to detect gas and is compatible with both Yokogawa devices and devices from other vendors. By giving customers a greater range of field instruments and analytical sensors to choose from, Yokogawa expects that this multi-protocol wireless adaptor will greatly facilitate the introduction of field
Support of multiple standards
The first two models are intended for wired HART and RS485 Modbus communications, both of which are widely used in plants. Yokogawa plans to release models that are compliant with other wired field communications standards such as FOUNDATION fieldbus and PROFIBUS. Battery power source for field instruments and analytical sensors
The battery in the multi-protocol wireless adaptor can also power the field instrument or analytical sensor, eliminating the need for wiring. As with other Yokogawa field wireless devices, the multi-protocol wireless adaptor uses a large-capacity lithium-ion battery, and this is able to power both the multi-protocol wireless adaptor and the field instrument or analytical sensor for a long time. An indicator on the host system shows the estimated remaining days of battery life.
