DMTF Publishes PICMG IoT.x IP Submission into Redfish API Specification

  • PICMG IoT.1 interoperable data modeling capabilities have been included in the latest release of the DMTF Redfish specification.
  • In addition, the work extends 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 PICMG IoT.x data modeling was accepted and included into the most publication of 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, IoT.2, which adds 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 much 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/effecter 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.

Then newly introduced job model extends 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 the 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 line with the release of the next Redfish specification release later this year.

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