"Wireless Anywhere” Concept Expands Use of Field Wireless Systems Based on the ISA100.11a Standard
Yokogawa (Netherlands) have announced the introduction of a new “Wireless Anywhere” business concept on the plant-wide use of ISA100.11a*1 compliant wireless communication technologies for both monitoring and control applications. Yokogawa will aggressively promote this concept to widen the use of ISA100.11a-compliant products and related services. This augments their existing “Grow” concept, which encourages the introduction of wireless communication technologies by making a case for their inherent reliability, flexibility, and openness.
The ISA100.11a standard ensures high reliability, application flexibility, network expandability, and compatibility with a variety of wired communication standards such as FOUNDATION fieldbus, HART, and PROFIBUS. “ISA100.11a full functional” field wireless network systems and devices make use of state-of-the-art dual redundant technologies that enable a much higher level of reliability, and allow massive scalability and long-range
By following up on the Grow concept with this announcement of the Wireless Anywhere concept, Yokogawa is advocating the use of “ISA100.11a full functional” field wireless systems throughout plants. To this end, Yokogawa will pursue the following three initiatives:
Modularising wireless components to accelerate product development. Yokogawa will develop modularised wireless components that incorporate the various technologies in its field wireless devices. This will make it easier for vendors to implement the ISA100.11a technology in new sensor products, and accelerate time to market. By the end of 2013 Yokogawa plans to begin releasing new field wireless devices with these components.
Promoting adoption of the ISA100.11a standard. Yokogawa will work with other members of the ISA100 Wireless Compliance Institute (ISA100WCI) to increase the number of WCI member companies and promote acceptance of the ISA100.11a standard, thereby expanding the field wireless market. To make a wider range of ISA100.11a-compliant products available to the market, Yokogawa may supply modularized components to other vendors.
Facilitating host connectivity for both wired and wireless field networks. To encourage the use of field wireless systems in both monitoring and control applications, Yokogawa will seek to improve the effectiveness of plant-wide field digital networks by making it possible for wired and wireless field devices and systems to connect with host monitoring and control systems. This will necessitate the development of technologies that will ensure host systems and field devices can communicate with each other using a variety of protocols. For example, an ISA100.11a-compliant adapter would enable a wired field device to link up with a wireless network.
For continuous processes that need sophisticated wireless control technologies, Yokogawa released the world’s first ISA100.11a compliant system devices and transmitters in July 2010, giving customers an expanded range of device choices. In July 2012, Yokogawa released a reliable, large-scale field wireless system for plant use.
Such systems ensure responses in real time by making use of state-of-the-art dual redundant technologies and can be quite large in scale, supporting connections to up to 500 field wireless devices. The data update time is 5 seconds when the system consists of a host system and 500 field wireless devices, and 1 second with a host system and 200 field wireless devices. The field wireless devices are proven to be able to communicate over distances up to 10 km*2, 20 times the range of conventional systems.
Reader Reply Card No 129 Wireless Pre-Engineered Essential Asset Monitoring Solutions Integrated application solutions monitor more key assets 24/7 to avoid shutdowns, slowdowns and reduce maintenance, energy costs.
Emerson Process Management has announced the availability of Essential Asset Monitoring solutions, the industry’s first family of integrated wireless application solutions for equipment monitoring.
The pre-engineered monitoring and analysis solutions embed process and equipment knowledge into a wide range of applications and use existing wired and new wireless instruments to form a network for continuous automated expert monitoring. Integrated solutions are available for pumps, blowers, compressors, heat exchangers, fired heaters, corrosion, and cooling towers.
The new 24/7 online monitoring solutions reduce monitoring costs through pre-engineering savings and wireless efficiency. Whereas wired continuous monitoring is traditionally afforded for only the most expensive and critical assets, the lower costs of Essential Asset Monitoring solutions enable expanded asset oversight.
"Equipment failures are a common cause of outages and incidents," commented Tom Snead, President, Global Projects, Emerson Process Management.
"Predictive monitoring by Essential Asset Monitoring solutions delivers diagnostics as well as equipment and process health alerts that enable timely corrective actions to keep the facility online, increasing production availability and savings on maintenance and energy costs."
Snead continued, "Our research has shown that unit or site-wide Essential Asset Monitoring application solutions can help owner-operators increase production capacity by 1.2%, save 14% of maintenance costs, and 2% of energy costs."
The pre-engineered solutions are scalable. Users simply choose the number and type of applications that monitor threats specific to their facility. Their resulting solution will include a wireless field network communicating data from monitoring instruments to AMS Suite operator graphics and maintenance screens, and to host systems and data applications.
Reader Reply Card No 130 New Touch-Screen for Gas Chromatograph Series
ABB (USA) have announced the release of the new touch screen for the PGC5000 series process gas chromatographs. The new front panel is now the standard configuration for the PGC5000A Master Controller and upgrade kits are available for all PGC5000A Master Controllers installed in the field.
This innovative touch screen panel fully integrates into the current design and provides redundant local user interfaces with the integrated mouse touch pad. The touch screen seamlessly replaces the current PGC5000A Master Controller front panel and is available for all hazardous area certifications.
In addition to the touch screen panel release, the latest version of PGC5000 Software, V3.0.2.X, now provides users a new local and remote method for chromatogram reprocessing. Along with the PGC5000 advanced graphical method editing, the chromatogram reprocessing provides operators the ability to optimise and fine tune a process gas chromatograph without maintenance downtime. Version 3.0.2.X has a new peak integration algorithm which uses the first and second derivatives on the chromatogram baseline to accurately and repeatedly determine the beginning and end of each measured peak. The algorithm further enhances the ability to precisely tangent skim unresolved peaks. This new method improves the analyser performance for tighter process unit control and offers greater flexibility with component separation and integration.
Reader Reply Card No 131 Process GC with EXp Proof Cabinet
Process GC’s aim is to propose a solution adapted to specific conditions required in some industries such as refineries. In this sense, Chromatotec (France) is glad to offer you their range of analysers with an EXp proof cabinet developed especially for such applications. It is a specific solution for hazardous atmosphere and fulfills the conditions of CSA international Class I, Division 2, group C&D.
A MEDOR EXp instrument is a good solution for sulphur compounds analysis (H2S, Mercaptans, DMS…). This analyser is composed with an automatic injection valve, an analytical column and a sulphur specific detector based on liquid-gas reaction. Installed in an explosive proof cabinet, it can be controlled
thanks to its remote system. The Vistachrom software will offer you a big range of opportunities, from data display to data storage and re-process of an obtained chromatogram.
Finally, for American customers a group has been created to develop a new ASTM method (2009) for online measurement of sulphur compounds in natural gas and gaseous fuels by chromatograph. This method is based on Chromatotec's MEDOR range. Reader Reply Card No 132
