With Release 3 of the CompactPCI Serial specification, PICMG doubles the bandwidth and speed of CompactPCI Serial applications. This benefits sectors such as aerospace, industry and automotive.

Wakefield, MA. March 11, 2025. PICMG – a leading consortium to develop innovative open standards in embedded computing – today announces the release of CompactPCI Serial^® Revision 3 (CPCI-S.0 R3.0). With the third revision of the standard, the organization is ensuring future viability and scalability for many years to come. CompactPCI Serial^® was originally developed as an extension of the open CompactPCI^® standard to meet the demand for robust, modular and powerful computer systems in industrial and embedded applications. The combination of high performance, modularity and robustness has made CompactPCI Serial^® a popular standard for industrial applications, automation, and much more – where robustness, interoperability and use in harsh environments with comprehensive connectivity are crucial.

CompactPCI supports serial data transfer rates via PCI Express, USB, and Ethernet, a robust design with AirMax connectors and full interchangeability with CompactPCI cards via 3U/6U slot card systems. Developers can look forward to the completely new opportunities offered by revision 3 compared to revision 2, which are among others:

• Full PCI Express (PCIe) support: While R2 supported PCI Express up to Gen3 with 8 GT/s, R3 extends support to PCI Express Gen4 with 16 GT/s, which means increasing speed by doubling the data rate.
• USB support: USB interface support has been increased from USB 3.0 (Gen1) with 5 Gb/s in R2 to USB 3.1 (Gen2) with 10 Gb/s in R3, doubling the bandwidth.
• Ethernet: R3 introduces support for 10GBASE-T and 10GBASE-KR Ethernet, enabling higher bandwidth network speeds.
• Connectors: In order to realize these higher data rates, new AirMax VSe^® high-speed connectors for CPU boards are used in R3 instead of AirMax VS^® in Release 2. These connectors are fully upwards and downwards compatible.

“I am very proud that with Revision 3 of the specification, we have managed to provide all embedded integrators with better CompactPCI Serial performance. Developers can look forward to better connectivity, higher performance and much better scalability,” said Jess Isquith, President of PICMG.

The CompactPCI specification defines a modular computer system, consisting of a backplane, a system slot, and up to 24 peripheral boards. The mechanical design is fully backward compatible to CompactPCI^® and will interoperate with existing systems. A system slot board can be used in a peripheral slot as well to do multiprocessing. The easiest way to communicate in this case is via Ethernet. Ethernet uses cable standards ‘xxBase-T’ instead of dedicated backplane standards. This lowers the cost, guarantees better interoperability and offers currently up to 10 Gb/s data throughput. Plus, implementation of the Ethernet connection of a system board can be done with a mezzanine board (3U or 6U). Due to this concept, more flexibility will be achieved, because the usage of Ethernet does not depend on the system board itself.

CompactPCI Serial can be combined with existing CompactPCI boards by using a CompactPCI PlusIO system slot card. These hybrid systems offer an ideal migration path from parallel to serial connections. CompactPCI Serial for Space specifically addresses the extreme environment requirements for outer space. Developers who want to build applications for harsh environments in industry, aviation or more can now download the new specification from the PICMG website and start designing immediately. PICMG member companies are also already working on their first products based on the new specification. The release of revision 4 is even in preparation.

About PICMG

Founded in 1994, PICMG (PCI Industrial Computer Manufacturers Group) is a nonprofit consortium of companies and organizations that collaboratively develop open standards for high performance telecommunications, military, industrial, and general purpose embedded computing applications. Its original mission was to extend the PCI standard to non-desktop applications. There are over 140 member companies that specialize in a wide range of technical disciplines, including mechanical and thermal design, single board computer design, very high speed signaling design and analysis, networking expertise, backplane and packaging design, power management, High Availability software, and comprehensive system management. Equipment built to PICMG standards is used worldwide and anyone can build or use equipment without restriction (although certain technologies used for some military applications may be subject to U.S. export restrictions governed by ITAR rules). Key standards families developed by PICMG include CompactPCI®, AdvancedTCA®, MicroTCA®, AdvancedMC®, CompactPCI® Serial, COM Express®, SHB Express®, MicroSAM, COM-HPC. and HPM (Hardware Platform Management).

• PICMG IoT.1 interoperable data modeling capabilities have been included in the latest release of the DMTF Redfish specification.
• Ongoing work will extend the Redfish job model to support factory orchestration and management via cloud-based platforms like AWS.
• A reference Redfish server based on PICMG IoT.x is being developed on GitHub to demonstrate the potential of plug-and-play Industry 4.0 use cases.

WAKEFIELD, MA. PICMG, the consortium driving open standards for modular, scalable computing, and DMTF, have announced that an IP submission containing the PICMG IoT.x firmware specification was accepted and included in the most recent Work in Progress phase of the Redfish^® standard. The extensions to Redfish will streamline the creation of plug-and-play Industry 4.0 systems by connecting interoperable data models on IoT.x-enabled endpoints to software-defined converged infrastructure via the Redfish API.

Redfish is an IT industry standard commonly used for data collection and device management in equipment such as data center fans and coolant pumps. Since 2018, PICMG and DMTF have worked collaboratively to extend the capabilities of Redfish to automation and factory equipment, enabling remote management and control of robotic motion platforms, contextualized sensing systems, and other advanced control endpoints.

The result of those efforts is PICMG IoT.1 and IoT.2, which add extensions to DMTF’s Redfish standard, now included in the latest publication.

“DMTF specifies protocols, data formats, and models for interoperable management on control plane infrastructure including edge systems,” said Jeff Hilland, DMTF president. “Since a lot of what we do is applicable to edge hardware, it makes sense to work with PICMG as part of our alliance partner program.”

Extending Data and Control Capabilities

The PICMG IoT.1 firmware specification defines a standard data model for sensor makers and systems integrators, while PICMG IoT.2 addresses the data model and network architecture requirements for the integration of larger sensor/effector networks.

Together, the two specifications accelerate the development and deployment of smart sensors in Industry 4.0 applications. Redfish extensions integrate these capabilities in a larger system of systems context while remaining fully compatible with the PICMG IoT.x specifications.

PICMG is also working on extending the Redfish job model to support cloud-based scheduling and orchestration of factory equipment. This will allow industrial operators to leverage powerful cloud platforms like AWS to manage jobs all the way to control endpoints on a factory floor.

“Imagine a modular factory where every component is interconnected and fully plug-and-play not just at the sensor and effector level, but across the entire assembly line,” said Doug Sandy, CTO of PICMG. “A factory where every piece of equipment has its own associated Redfish service, workloads, and processing could happen wherever they need to, while operators could manage and monitor everything through a top-down hierarchy of building, floor, and line controllers.”

“That’s what PICMG and DMTF ultimately want to support. And with our current work on Redfish, we’ve taken a big step in the right direction,” he added.

Building the Factory of the Future

PICMG’s IP submission recently entered DMTF’s Work in Progress phase and is slated for a projected full release in 2025. During the Work in Progress phase, the development community will have the opportunity to review and comment on the new content of the specification so changes can be incorporated prior to the next Redfish release.

PICMG and DMTF also currently have a team working on an example implementation of the interoperable data environment, expressed in the form of an open-source server. Accessible on the PICMG GitHub repository, new functionality is being added to the server each month with the goal of it becoming fully functional in time for the next Redfish specification release.

The PICMG extension is publicly available on the DMTF website at: www.dmtf.org/sites/default/files/PICMG_DMTF_Work_Register_v1.1.pdf.

FEBRUARY 2024 ­­– WAKEFIELD, MA. PICMG, the consortium for open hardware specifications, today announced the release of InterEdge, a modular architecture for process control systems (PCS). The IEC 61499 and IEC 61131-compatible InterEdge specification promises to revolutionize the industry with an interoperable, multi-vendor alternative to proprietary Industrial PCs (IPCs), Programmable Logic Controllers (PLCs), and Distributed Control Systems (DCSs).

“Business needs evolve at an ever-increasing rate,” said Francisco Garcia, Americas Regional Instrument Lead at ExxonMobil Technology & Engineering Company and member of the InterEdge technical working group. “InterEdge delivers an interchangeable base hardware standard for industrial manufacturers looking to adapt to changing business needs. As a result, providers can deploy and scale dedicated physical assets and focus on value-added software and services.”

A Shared Standard for the Process Industry

InterEdge defines a vendor-neutral, open standard for edge computing and I/O module hardware. It segments hardware into Compute Modules, Switch Modules, and I/O Modules. All of these modules are connected via a common backplane, enabling easy customization and expansion of industrial automation functions.

An overview of the specification and an architecture diagram are available at https://www.picmg.org/openstandards/interedge/. InterEdge 0 R1 supports both single- and multi-channel I/O implementations and a forthcoming specification will be optimized for single-channel I/O.

The full specification is available to purchase. Interested parties are encouraged to participate in ongoing specification development efforts by joining the PICMG InterEdge working group by emailing [email protected].

With its modular approach, InterEdge can flexibly incorporate the functions of disparate automation systems into a single platform. This common platform can be deployed across automation, chemical refining, oil and gas, pharmaceuticals, metals and mining, pulp and paper, food and beverage, and a wide range of other process industries.

Upgradability that Breaks Free from Hardware Lock-In
By replacing proprietary edge devices, InterEdge eliminates vendor lock-in, simplifies integration and maintenance, and enables online upgrades, all of which contribute to significant cost savings.

In the past, edge components remained in place for decades with static functional capabilities due to the difficulties of upgrades. In contrast, the hot-swappable interoperability of InterEdge allows industrial organizations to quickly adapt to changing market demands and technological advancements. Now manufacturers can improve their competitive position through emerging trends in AI, Industrial IoT, and Industry 4.0.

“InterEdge allows industrial manufacturers to transition from proprietary hardware to an open architecture where they can choose fit-for-purpose components, replace obsolete hardware, add computational resources, and upgrade hardware security in a running plant at virtually zero switching costs,” said Matt Burns, global director of technical marketing at Samtec and chair of the InterEdge Technical Working Group.

“InterEdge does for industrial control systems what the Open Compute Project did for data centers,” Burns added.

Strong Support from Industry Leaders
InterEdge originated as part of the O-PAS™ (Open Process Automation) Standard from The Open Group® Open Process Automation™ Forum (OPAF), a consortium of 110+ leaders in process automation including system suppliers, engineering firms, governmental bodies, research institutions, and end customers.

With its new home in PICMG, InterEdge joins a growing family of multi-vendor hardware standards with a decades-long track record of success. PICMG and OPAF have committed to working together to push for the same widespread adoption of InterEdge.

“PICMG felt it was critical to release this because it lays the groundwork for subsequent iterations of the InterEdge specification that will address the broadest range of industry use cases possible,” says Jessica Isquith, president of PICMG. “We are eager to support the continued progress of InterEdge and its ability to revolutionize industrial edge environments.”
