Getting measurement and control signals to and from your instruments is central to your automation strategy. Yokogawa supports a wide variety of Fieldbus technologies, including conventional 4-20mA, wired digital networks, and wireless ISA100.11a. These technologies are employed at the device, host, and solution level, depending on your needs.
The flexibility of wireless solutions enables less investment in infrastructure while providing greater insights into plant operations.
Yokogawa is firmly committed to a single, international FieldBus, and we are partnering with our customers in this evolving digital communication technology.
Our easy-to-connect network converters connect RS485 devices or analog signals to DeviceNet communication PLCs.
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.
