Wireless device integration specification released
The Fieldbus Foundation's final specification for ISA100.11a Device Integration incorporates network protocols into its for Remote Operations Management (ROM) infrastructure.
The Fieldbus Foundation has released the final specification for integration of ISA100.11a wireless field devices into its Foundation for Remote Operations Management (ROM) technology. This development is said to allow automation end users to employ multiple wired and wireless protocols for greater flexibility and expandability. The Foundation specification means that end users can manage ISA100.11a wireless devices just like Foundation fieldbus devices within the Foundation fieldbus infrastructure.
Foundation for ROM will extend the capabilities of Foundation fieldbus to many wired and wireless devices installed in some of the world's harshest and most remote locations, according to sources at the Fieldbus Foundation. This includes the implementation of a true predictive and proactive maintenance strategy for remote assets that could not previously support one. Foundation for ROM provides a unified digital infrastructure for asset management in applications ranging from tank farms and terminals to pipelines, offshore platforms, and even original equipment manufacturer (OEM) skids.
With this release, the Fieldbus Foundation has finalized the remote I/O, wired HART and WirelessHART, and ISA100.11a portions of the Foundation for ROM specification. The technology integrates these protocols, along with H1 fieldbus, into the Foundation fieldbus managed infrastructure.
Specifications for Modbus communications are in development that will enable Modbus devices, such as wellhead flow meters and submersible pump controllers to be integrated in a similar way.
The new specification includes parameters for ISA100.11a transducer blocks, providing the block application objects into which ISA100.11a variables may be mapped for access by other fieldbus devices. The transducer blocks also provide a mechanism to pass data to and from ISA100.11a devices directly from configuration or asset management hosts.
The Fieldbus Foundation's ROM infrastructure provides a single source for data management, diagnostics, alarms and alerts, data quality control, control-in-the-field capability, and object-oriented block structure. Its High Speed Ethernet (HSE) TCP/IP protocol enables remote operations information to be communicated to the control system over any wired or wireless backhaul network using the architecture model developed in a joint collaboration between the Fieldbus Foundation and the International Society for Automation (ISA) under the ISA100.15 Wireless Backhaul Networks Working Group.
To ensure interoperability, Foundation for ROM devices from multiple suppliers utilize Electronic Device Description Language (EDDL) and interoperability testing. This is essential to improve integration of critical functional areas, including machinery health monitoring, safety interlocks, fire & gas detection systems, and video surveillance.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
