when using the system. According to Tyler, other users have gone as high as 10 per cent. Current users among operating companies include Chevron, Mobil, ConocoPhillips and
Celanese.Integrity is also helping Chevron as it goes through the process of standardising on Yokogawa Centum and migrating to it on all the company sites. “The company is using our system to capture ‘as-is’ data on a legacy system and then export it to the Centrum,” notes Lyden. Disaster recovery is another market, too, and Lyden cites
the case of a large refinery customer whose control room was flooded when Hurricane Ike hit the Gulf Coast. “They hadn’t done a good job of backing up, but Integrity was in place at the time. That was the genesis of our disaster recovery technology.” Then there is always the example of what can happen

and contextualizes tagged emails in the Integrity database where they can be searched and accessed or shared in context. There’s also a Data Mining facility for searching for specific patterns across all databases, systems and document, a Subscriber Notification function which sends updates to subscribers by web page, email or pager whenever the Integrity database is modified and an Amazon-like “If you loved this, you might also like …” Smart Guide to provide additional information based on context.
Integrity in action
Invensys Process Systems (IPS) has just announced that Integrity Automation Genome mapping software will be utilised by project teams within Invensys Operations Management’s delivery organisation, enabling collaboration among multiple Invensys Operations Management teams. IPS has already reported 3-7 per cent improvement in performance
without Integrity technology. Here, a major North American petrochemical facility
extended the periods between turnarounds, which forced the company to perform online interlock testing. The procedure called for bypassing an SIS output and ramping the transmitter value to test the interlock. As expected, the interlock in the SIS tripped, but did not
trip the shutdown valve. Due to inadequate documentation, the testers were unaware of a configured link to operator start-up assistance logic in DCS. The DCS logic sensed the interlock trip, placed all controllers in manual, and set all valve outputs to the fail-safe position (shutdown). The consequences of this included a loss of production
estimated at US$150 000 and regulatory fines for breaking flare limits estimated at US$25 000. “Had someone understood what was in their automation,
they could easily have disabled that bit of logic. If Integrity had been in place, the incident would have been prevented: but it took this event for people to realise their exposure,” concluded Tyler. n
Wireless POINT I/O modules for distributed automation applications
he new Wireless POINT I/O Adapter (ILX34-AENWG) is a high-speed, standards-based 802.11g wireless I/O adapter. It takes benefits of the compact size of the 1734 POINT I/O systems (distributed Input/ Output modules) from PLC/PAC manufacturer Rockwell Automation, and combines it with ProSoft Technology’s Integrated Wireless Architecture.

When coupled with the Wireless, POINT I/O Adapter becomes ideal for collecting data from and for controlling moving systems (like robots, automated carts, overhead cranes, earthmovers), as well as fixed-position racks in hard-to-reach areas of the process plant.
Non-tethered link to distributed I/O is requested in applications with moving or remote equipment, or where it would be difficult or
costly to wire devices or control panels. These applications include: Tank farms (oil and gas, water treatment), cranes, stackers/reclaimers, rotating filling, spooling, molding machines (food and beverage), robotics/multi-axis machining, remote monitoring or condition monitoring. The ability to connect POINT I/O modules
wirelessly, allows Automation Engineers to design high-performance, scalable and low-latency systems in cases where wired I/O would be problematic.
The Wireless POINT I/O Adapter can be used in networks with RadioLinx Industrial Hotspots or third party 802.11g access points to provide high-speed, low latency 802.11g client communication over widely spaced plant areas. This ability to work with existing standards-based wireless technology protects and leverages the
end-users’ investment. For security, the Wireless POINT I/O employs 802.11i WPA2 with AES Encryption.
The Wireless POINT I/O Adapter provides users with the flexibility and scalability (up to 63 modules) offered by the many standard Rockwell Automation POINT I/O modules Features include: connection-based communication for the highest level of integration with Rockwell Automation controllers and software; simplified integration with a familiar programming environment; integrated web page for wireless configuration. n
