ISA 100.11a wireless demonstration project in operation

Wireless system installed at Arkema chemical plant seeks to prove device and infrastructure interoperability using equipment from multiple vendors operating under same standard.

10/08/2009


New technologies are typically launched with a demonstration project that puts the equipment to work in a real-life plant environment. In what may be one of the fastest deployment projects, the ISA 100.11a Wireless Compliance Institute (WCI) has completed an installation of a fully operational wireless instrumentation network following the new standard at the Arkema organic peroxide plant in Crosby, TX .

This project is already operating, even though the standard was ratified less than a month ago . It involves a group of specific monitoring points in the plant that were either inadequately instrumented or where the company wants to expand coverage. According to WCI, the devices are deployed in several areas:

• 500,000 gal. firewater tank: Wireless level sensor ensures firewater tank is full at all times;
• Cold storage: Wireless temperature and door sensors provide central reporting of exception conditions at cold storage warehouses;
• Wastewater tank: There is a wired level sensor on a wastewater tank that feeds its values into a satellite control room close to the tank, but not the central control room. To provide central visibility to this information, an ISA100.11a adaptor sends the data to the central control room; and
• Gas sensor: A single wireless SO2 sensor was installed alongside an existing wired sensor. Following successful pilot, wireless gas sensing can be expanded.

In many respects, the specific applications of the devices themselves are not as important as what the project demonstrates. The point that WCI is trying to prove is that ISA 100.11a can be a multi-vendor platform with full interoperability. The devices in this case are made by Honeywell, Yokogawa, and Gastronics, with the wireless infrastructure provided by Honeywell and Nivis. WCI members make the point that while these individual devices were essentially hand made, the communication stacks and testing tools were already complete before the final ratification, so the transmitters were tested and are fully compliant with the standard.

The companies participating in the demonstration wanted to make sure that the system showed all the critical operational elements, including device level meshing. 11a is designed to be a one-hop topology, although devices can send signals through the mesh if a direct connection with the gateway is not possible at any given time. Working with Arkema, the participants had to create a barrier using some strategically placed steel shipping containers, but the system responded as expected and routed the transmission around the impediment.

At present, the wireless devices feed into a separate monitoring point, but Arkema expects to integrate them fully into its main control architecture as well as adding more devices as they become available.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
