The Show(s) Must Go On

We’re only through the first quarter of 2024 and we’ve seen two new specification families introduced, multiple new specifications released, a call for participation on a new version of a familiar technology (AdvancedTCA), strengthened partnerships with multiple standards organizations, and more.

Later this month PICMG will be sponsoring the IEEE Real-Time Conference (RTC) in Vietnam, which serves as rallying point for a critical emerging deep tech economy (https://indico.cern.ch/event/940112/program). We will act as an umbrella for multiple members who develop and deliver products into this sector, and also participate in a Women in Engineering (WiE) event (https://indico.cern.ch/event/940112/page/33210-women-in-engineering-wie-event).

Later this year we will visit Embedded World North America in Austin, the MicroTCA Summit in Hamburg, and many more in-person and virtual events in between. Right now is one of the more exciting times in PICMG’s 30-year history, and I feel fortunate to be part of it.

• Partnership seeks to reduce technology integration, maintenance, and upgrade costs in the process automation industry.
• Work supports the Open Process Automation™ Standard (O-PAS), a standard of The Open Group, that defines resilient and scalable process automation system architectures.
• Collaboration establishes a multi-vendor ecosystem for interoperable, interchangeable edge hardware via specifications like InterEdge.

WAKEFIELD, MA. PICMG, the consortium for open hardware specifications, has entered a liaison partnership with The Open Group Open Process Automation™ Forum (OPAF) to collaboratively develop interoperable, interchangeable technology specifications for the process control industry. The partnership fills a gap in edge controller hardware that exists in the O-PAS™ Standard—an open architectural framework for developing industrial process automation systems, currently being defined by OPAF initiatives.

Governed by The Open Group, OPAF membership is comprised of 110+ member organizations, including companies like Exxon Mobil, Schneider Electric, Phoenix Contact, Intel, and others. These companies work collaboratively to address the needs of end users in the process control market through initiatives like the O-PAS Standard. The O-PAS framework references existing standards wherever possible or, in the absence of such standards, works with associated organizations to achieve proper standard definition.

To complete and standardize work on an edge controller performed by OPAF member Georgia Tech Research Institute (GTRI), The Open Group forum evaluated several hardware standards development organizations. The OPAF Members selected PICMG to develop a new open edge hardware technology specification that defines electromechanical interoperability, interchangeability, hot plug capabilities, and compatibility with existing standards such as IEC 61499 and IEC 61131.

The result was the recently ratified InterEdge specification.

Collaborative Standards Development Yields InterEdge Specification
Founded in 1994, PICMG is a consortium of more than 150 member companies that defines open, interoperable, and multi-vendor technology specifications for high-performance embedded computing platforms. With a heritage of specifications that span edge-to-cloud use cases, including CompactPCI, AdvancedTCA, and COM Express, PICMG brings a proven process and track record of successfully producing lasting, quality technology specifications.

“During development of the O-PAS Standard, we realized the need for physical hardware that provided interchangeability in an interoperable way,” explained David DeBari, Process Control Engineering Associate at ExxonMobil. “Because our focus is primarily on the software side, we opted to bring in third-party expertise. PICMG was the organization that best fit our needs in that regard—a lot of our suppliers were involved with them already, so working together was the natural choice.”

The InterEdge specification introduces a modular open architecture that delivers state-of-the-art I/O abstraction and flexibility and in a common physical form factor. It supports the OPAF and O-PAS goals of reducing integration, maintenance, and upgrade costs in the highly fragmented and largely proprietary process control technology market.

Collaboration for A More Open Industry
The OPAF and PICMG relationship is ongoing, with work on new versions of the InterEdge specification already underway. Meanwhile, the Open Process Automation Forum has introduced InterEdge to its physical platform subcommittee, who plan to include the specification in an upcoming revision of the O-PAS Standard and devise a set of tests that evaluate conformance to the InterEdge specification.

“Through standardization, proprietary physical interfaces are quickly becoming a thing of the past. The InterEdge standard from PICMG is the first step in that transition for process automation industry end users. Enabling hardware interchangeability allows end users to select components based on performance characteristics instead of physical interface compatibility. We look forward to seeing this key quality attribute normatively referenced in the O-PAS standard”, added Aneil Ali, Forum Director of The Open Group Open Process Automation Forum.

“Our relationship with PICMG is invaluable. It is industry changing,” Steve Bitar, former ExxonMobil automation advisor and secretary of the PICMG InterEdge working group. “And we already know that some of our vendors will use—or are already using—other PICMG standards like COM-Express and COM-HPC. That level of collaboration and integration brings us a step closer to our vision—an industry built on open architecture standards and qualifications that are supported by end users, suppliers, and integrators alike.”

Highlights:

• Carrier Design Guide helps hardware engineers design application-specific carrier boards for COM-HPC-based systems.
• Revision 2.2 of the Carrier Design Guide introduces new diagrams, figures, and design notes for COM-HPC Mini.
• Document contains technical materials such as interface schematics and practical guidance on design rules.

WAKEFIELD, MA. PICMG, a consortium for open hardware specifications, has released revision 2.2 of the COM-HPC Carrier Design Guide. This comprehensive document contains interface schematics, diagrams, design rules and requirements, and more for PCB layout engineers and hardware developers looking to create application-specific carrier boards that pair with COM-HPC modules.

Revision 2.2 of the Design Guide includes updates to address the new COM-HPC 2.1 specification, nicknamed COM-HPC Mini, which is the 95 mm x 60 mm platform that uses one less connector compared to its fellow COM-HPC form factors, but still delivers 400 pins for carrying high-speed signals from the processor module to carrier boards.

“Designing a carrier board can be a complex and time-consuming process, but the COM-HPC Design Guide helps streamline that process” says Peter Hunold, head of hardware engineering at Kontron Europe GmbH and editor of the COM-HPC working group. “It serves as an excellent complement to the COM-HPC base specification, as well as, for revisions like COM-HPC 2.1 that introduced the new “Mini” form factor and vendor documentation.”

What’s New in COM-HPC Carrier Design Guide Revision 2.2

Revision 2.2 of the Carrier Board Design Guide primarily focuses on the COM-HPC Mini, a small form factor expansion of the COM-HPC standard first announced in 2022. This new guide clarifies the differences between COM-HPC Client and COM-HPC Mini carrier board requirements, with examples that illustrate modifications necessary to move from Client- to Mini-compatible designs.

The Design Guide 2.2 release also introduces information on the Intel JHL9040R USB4 Retimer, which replaces the JHL8040R in Rev 2.1. In addition to updated references, the document includes Intel JHL9040R block diagrams for both COM-HPC Client and COM-HPC Mini designs.

“Designing hardware to support new and emerging workloads is becoming progressively more challenging. Open standards such as COM-HPC help businesses overcome those challenges,” says Christian Eder, director of market intelligence at congatec. “They considerably reduce time-to-market for even the most sophisticated applications, especially with documentation to streamline the design process.”
