YFGW410 Field Wireless Management Station is based on wireless communications standard ISA100.11a for industrial automation of International Society of Automation (ISA). This product has system manager/security manager/gateway function based on ISA100.11a, and combining this with Field Wireless Access Point (YFGW510) and/or Field Wireless Media Converter (YFGW610) composes the field wireless system.
Adoption of discrete-type architecture enables a redundancy configuration by connecting two products. A highly flexible operation is also possible where the field wireless system under operation does not have to be stopped and maintenance can be performed on line.
This product supports the access control list (IP filter and port filter), preventing unauthorized access, and role-based password-protected secure user interface. End-to-end communication of ISA100.11a is encrypted with AES 128bit. Robustness of the communication and security is validated as it achieves Achilles Level 1 Certification.
This product can encapsulate foreign protocols such as HART and Modbus and transfer them between devices and host systems. By transferring safety communication protocol such as PROFIsafe between a Safety Instrumented System (SIS) and wireless safety devices and thus contributes to achieving required Safety Integrity Level (SIL) for the entire safety system.
This product can utilize the bandwidth of the field wireless network flexibly for achieving reliable and efficient wireless communication. Duocast function enables receiving data simultaneously with two backbone routers (BBR) connected to this product. The built-in data cache function saves bandwidth of the field wireless network and energy consumption of the field wireless devices.

One important risk to manage with regard to coal stacks is preventing fires due to spontaneous combustion.
A battery room is used to storage batteries for emergency power management in the plant. Each substation has battery room and the storage batteries are lead-acid batteries which must be maintained within specified operating temperature limits. Temperature management is important to ensure a long service life of the batteries especially for the plant in desert climates.
Delayed Coker is a type of coker who's process consists of heating residual oil feed to its thermal cracking temperature in a furnace. The most important variable in industrial furnace control is temperature. Temperature is measured throughout the furnace in different zones and temperature effects the materials being manufactured and therefore must be precisely monitored to prevent deviations in quality of the final product.
Blending plays a key role in industries such as food, healthcare and chemicals etc. Temperature and vacuum measurements are very important in minimizing the moisture content to ensure the quality of the final product. Strictly maintaining them throughout the process ensures the final product yield.
An induction furnace melts metal by creating very large currents in the material. These currents are induced using three electrodes positioned inside the furnace. The furnace is automated so that once the material has been melted, the electrodes are removed and the furnace then tips the molten metal into a crucible where it can be easily transferred to the production line where it will be cast into ingots. The atmosphere is extremely aggressive and the wired infrastructure is both expensive and very unreliable to maintain. The furnace control requires a total of 20 measurement points distributed around and inside the furnace. The harmonic field effects caused by short circuit 40,000 A (300V). The causes significant interference.
Customer needed efficiency improvement of steel manufacturing by temperature monitoring for heat/cooling equipment. Previous system required periodic compensation lead changing.
The client wanted to monitor the temperature on a chimney. Exhaust air is exposed to the heat on the way traveling from the inlet to the outlet in the chimney. Then constituent of the air transform to harmless elements. It is important to keep the temperature in the chimney as designed.
Direct Reduction Iron (DRI) is one of the processes to reduce oxygen from iron oxide pellets for steel plant. More than 90% of DRI processes use heated LNG as process gas where PID control for temperature or interlock control is of vital importance.
Pressure measurement of tubeless tyres to monitor the air loss is one of the key performance tests in the tyre manufacturing units. Relocation of tyres from one testing rack to the other for various tests and frequent movement of the testing setup for conditional tests to various locations calls for cable free implementation for ease of handling.
Wireless technology has a long history, and it began around the time that James C. Maxwell theoretically predicted and then proved the existence of electromagnetic waves in the 1860s, and when Heinrich R. Hertz experimentally confirmed the actual existence of the electromagnetic wave in 1888.
In plant sites, there are various places such as those affording an unobstructed view like tank yards, and others surrounded by metal pipes and equipment obstructing the view (hereafter referred to "pipe jungles"), often seen in oil refinery and chemical on-site plants. The frequency band of radio waves used for field wireless communication is 2.4 GHz, which has high straightness and its ability to go around things can hardly be expected.
The introduction of wireless technologies into plants is anticipated as one of the measures for implementing field digital solutions not only to reduce cable wiring costs but also to improve plant wide safety/stable operations, operating efficiency, and so on.
The FieldMate versatile device management wizard is PC software mainly used for configuring and adjusting field devices. Under the concept of "one tool for all," Yokogawa has been enhancing this software to support a wide range of field devices and field communication protocols.
In recent years, expectations for control systems using wireless communications have been increasing in the process control market. This is because these systems do not require power and communication wiring for field instruments, enabling reduced initial and maintenance costs, and easy installation.
