Wakefield, MA., USA / Nuremberg, Germany, June 23, 2022 – The PCI Industrial Computer Manufacturer’s Group (PICMG), a leading consortium for the development of open embedded computing specifications, is excited to announce significant progress on its IoT.X family of specs. Highlighted by the IoT.1 firmware interface and data modeling specification and soon-to-be-ratified IoT.2 network architecture, ongoing efforts promise to abstract low-level device physics such that sensor node data becomes interoperable across all levels of smart factory deployments.

PICMG IoT.1 focuses primarily on a data abstraction layer that allows users to turn traditional sensors and effecters into plug-and-play smart sensors and effecters using free and open-source tools that require little-to-no programming expertise. For example, the PICMG IoT Configurator and IoT Builder tools are reference implementations for building and generating smart sensor firmware that can be read by any sensor or controller.

Both can be accessed from the PICMG Github repos

The separate but complementary IoT.2 network architecture specification defines the integration of these smart sensors and effecters, as well as their data, into larger Industry 4.0 systems of systems. Based on the Data Management Task Force’s (DMTF’s) Redfish API, the .2 spec outlines an abstraction layer and transactional model so that sensor and effecter endpoints can be monitored and managed in the context of job models similar to those available from major cloud service providers.

In other words, the data transparency afforded by the two specifications permits IT factory personnel to send specific, state-based jobs to a machine or clusters of machines in the pursuit of a desired outcome.

“IoT.1 provides low-level visibility of physical device parameters that can directly impact the quality and efficiency of your production line,” says Doug Sandy, CTO, PICMG. “IoT.2 provides an IT-like interface for managing both machines and jobs at a high level of abstraction.

“When used together, they support the analytics required for higher levels of productivity and throughput across a factory environment,” he adds.

To foster an environment of openness and collaboration, IoT.2 will not be exclusive of other existing IoT communications protocols and models and allows them to be converted to maintain compliance with the new spec.

Wakefield, MA., USA / Nuremberg, Germany, June 23, 2022 – PICMG – a leading consortium for the development of open embedded computing specifications – announces two new specifications for the high-end Computer-on-Module standard COM-HPC. They target mixed-critical functional safety applications and small form factor designs requiring credit card-sized modules.

COM-HPC Client Mini

Like COM Express Mini, the COM-HPC Client Mini specification will define the use of one connector instead of the two implemented for the larger modules (Sizes A -E). But with COM-HPC, half the number of signal pins still means 400 signal lanes, which equals 90% of the capacity that COM Express Type 6 modules offer. Compared to COM-HPC Client Size A modules, the smallest available COM-HPC form factor, COM-HPC Mini, also reduces the footprint to 50%. Such extremely small modules measuring only 60 x 95 mm are required for high-end embedded computer logic in devices such as top-hat rail PCs for control cabinets in building and industrial automation, or portable test and measurement devices. In addition, the new specification will enable engineers to integrate state-of-the-art computer interface technologies such as PCIe Gen4 and Gen5 into ultra-small processing units that provide highest performance. As the new specification will come with a focused high-performance pinout and will comply with the entire COM-HPC ecosystem, it is expected to become the high-end standard extending the PICMG’s earlier COM Express Mini standard. PICMG expects the COM Express specification to continue leading the COM market for many years as it meets numerous standard application requirements now to be allocated in the mid-range performance sector.

FuSa support: COM-HPC
The new version of COM-HPC defines signal pinouts to support FuSa (Functional Safety) applications. These applications include safety critical machine control, autonomous vehicles and robotics, transportation related hardware such as train and wayside control, avionic equipment and much more.

The new extensions for functional safety (FuSa) target an even more promising market: Connected device developers want to utilize x86 processor technologies to be able to execute mixed-critical applications on multi-core processors. This requires redundancy and the possibility of implementing fail-safe processes. With the new functional safety extensions, COM-HPC is thus entering a market that is expected to accelerate the demand for embedded Computer-on-Modules significantly. Besides functional safety control applications that require an IoT and industry 4.0 gateway, it also targets collaborative robotics working closely with humans. Further markets arise from the demands of automated intralogistics with autonomous logistic vehicles and stretch from factory mobility to any new market that can be found in autonomous driving, from agricultural and construction machinery to smart city vehicles and AUVs as well as UAVs. Of course, the functional safety extensions are supported across all COM-HPC form factors, including the upcoming COM-HPC Client Mini.

„With the small size definition of the COM-HPC Client Mini and the FuSa extensions, COM-HPC covers all embedded use cases I can think of. COM-HPC is the most complete computer module definition ever. I expect an extremely fast growth for scalable and compute-power hungry embedded applications based on COM-HPC technology.“ Christian Eder, Chair of the COM-HPC technical committee and Congatec Director Product Marketing.

The FuSa specification in detail
FuSa versions of some contemporary chipsets or System-on-Chips (SoCs) incorporate a FuSa “Safety Island”. This is a specialty portion of the hardware – along with supporting firmware and software – that is separate from the main portion of the chipset or SoC. The Safety Island monitors the health and status of the main chipset or SoC and can report any findings over a dedicated FuSa GPIO and dedicated FuSa SPI Slave interface to an external carrier based FuSa System Safe State Agent and optionally a Safety Controller. The FuSa “Safety Controller” is a carrier based microcontroller that collects safety and status information from the Safety Island over a dedicated SPI bus and processes it for external use. The Safety Controller is the FuSa SPI Master.

The efforts of both new specifications are sponsored by: congatec, Kontron and ADLINK

ModBlox7 introduces an open standard to proprietary multi-billion USD market

PICMG, a leading consortium for developing open embedded computing specifications, announces a technical subcommittee formed to create a new PICMG form factor specification named ModBlox7. This specification will transform the multi-billion dollar Box PC industry by introducing an open standard to what is currently a proprietary market. Box PCs are highly integrated computing solutions, but the lack of interoperability limits the ability for end users to achieve truly cost-effective and sustainable solutions.

The ModBlox7 specification will describe a compact and modular Box PC that is flexibly configurable and can be wall-mounted, snapped onto a DIN rail, or integrated into a 19” subrack. The height and depth are fixed; the width is variable in multiples of 7HP. The maximum length is 84HP. The modular Box PC designs will be very robust, support passive conductive cooling, and be used for demanding applications such as railway, avionics, mobile machines and autonomous mobility as well as machinery in discrete manufacturing and controls in critical process industry infrastructures. The result of the committee’s work will be a basic specification describing the housing mechanics, the modular functional units, and the electrical interconnection of the units. The standard will guarantee interoperability of units for manufacturers as well as interoperability for users of the Box PC, while combining the advantages of modular systems and highly integrated cost-sensitive Box PC solutions.

The open specification will contain the following requirements or specified functions:

• Cost-efficient design with minimum mechanical effort. No additional backplane or heat sink will be required. Coplanar board-to-board connectors couple each unit to its neighbor and route defined I/O interfaces (PCIe and USB) to the next board. 
• Modular, functionally encapsulated plug-in units in multiples of 7HP width pitch. Units form functional assemblies such as power supply, CPU, switch and I/O. Units can be multiples of 7HP, e.g., implement more interfaces or functionality in a single building block assembly.
• This results in a wide range of device combinations in a modular design in increments of 7HP (21HP, 28HP, 42HP to 84HP), making it cost-efficient even in small quantities.
• Each modular computing unit can host a stack of 1, 2, or 3 PCBs – depending on the complexity. Separation is typically made according to the front I/O and the power and communication requirements between the host unit and its expansion units.
• Flexible mounting with minimal accessory components for wall, din-rail, and 19″ subrack installations.

“For industrial end users, the advantages of an Box PC open standard lie in the cost-effective design of the dedicated systems and the flexible interchangeability of components to tailor the platform for dedicated tasks. Manufacturers also benefit, as the interoperability between the units strengthens their core competence, and they do not have to develop each unit and its embedded components such as cables and mechanics themselves. For VARs and system integrators, the new ecosystem will provide faster configuration options with components from multiple vendors,” states Mathias Beer, chief product officer at Ci4Rail.

According to Markets and Markets, the global industrial PC market size is estimated to reach USD 6.1 billion by 2026 from USD 4.6 billion in 2021, growing at a CAGR of 5.8%. The market growth is fueled by increasing demand for industrial IoT, a steady shift towards digitalized manufacturing from traditional manufacturing, growing awareness for resource optimization in manufacturing industries, and stringent regulatory compliances.

The goal is to have the specification ratified by the end of 2022. The team has elected Bernd Kleeberg of EKF Elektronik as chairman of the committee. Manfred Schmitz of Ci4Rail is the technical editor, and Johann Klamer of ELTEC Elektronik acts as secretary.

This initiative has over 15 active member companies, including: ADLINK, Ci4Rail, EKF Elektronik, Elma Electronic, ELTEC Elektronik, Embeck, ept, General Micro Systems, HEITEC, Hirose Electric, Intel, Kontron, nVent, Schroff, Samtec, Sealevel Systems and TEWS TECHNOLOGIES. Further vendors are invited to join the committee to actively develop the new modular Box PC open standard.
