계측 및 제어 신호를 계측기와 주고받는 것은 자동화 전략의 핵심입니다. Yokogawa는 기존 4-20mA, 유선 디지털 네트워크 및 무선 ISA100.11a를 포함하여 다양한 Fieldbus 기술을 지원합니다. 이러한 기술은 필요에 따라 장치, 호스트 및 솔루션 수준에서 사용됩니다.
무선 솔루션 유연하게 적용함으로써 인프라에 대한 투자를 줄이면서 플랜트 운영에 대한 더 많은 이해할 수 있게 도와줍니다.
Yokogawa는 다양한 통신 프로토콜을 제공합니다. FOUNDATION Fieldbus, HART, BRAIN, ISA100, Profibus 및 Modbus를 비롯하여 진화하는 디지털 통신 기술을 통해 스마트 장치에 적용할 수 있도록 지원합니다.
Plug-in type, RS232C/RS485 dual directional converter with two ports of RS232C and RS485, and perform isolation of communication signal, level conversion and active control of driver.
The changes in social environment, such as globalization of enterprise activities, depletion of natural resources, and eco-oriented movement will affect the structure of mass production. Control systems must be prepared with flexibility and scalability in both size and function to adjust to the changes.
To configure a compact, low-power medium attachment unit for field buses, i.e., a fieldbus MAU, an IC comprising a power generator, transmitter/receiver and other functions is needed. While we at Yokogawa had already developed a fieldbus MAU IC, we have now developed another MAU IC that includes large-scale design changes made mainly to comply with the low-power signaling requirements of the fieldbus specifications.
Progress in digital signal processing and network technologies has enabled advanced functions which cannot be achieved by traditional field devices with 4-20 mA signal, to be implemented on field devices. Standardization of international fieldbus specifications, notably the FOUNDATION™ Fieldbus, has enabled users to build optimum field networks comprised of freely chosen field devices from various device vendors.
Here's how Shell upgraded from a pneumatic instrumented plant to a fully digital control system.
Decades of operation, modernization and expansion have left many chemical plants with a somewhat haphazard automation mix of different controls, process control systems, remote I/Os and field devices. The various components may use different communication protocols such as HART, PROFIBUS or FOUNDATION Fieldbus, and are often based on different device integration technologies.
