A paper describing an application of the IEEE 1588 industrial networking standard to industrial automation outlines the ways in which manufacturers can improve control-system responsiveness and accuracy. An Application of IEEE 1588 to Industrial Automation identifies key industrial applications that can benefit from the Precision Time Protocol defined by IEEE 1588 and discusses how IEEE 1588 can be adopted for those applications.
The applications discussed include logging and scheduling, alarms and events, high-speed inspection, and motion position and velocity control. The paper concludes:
The IEEE 1588 standard is ideal and easily adaptable for distributing a precision time-base to all devices of the control system. The challenge will be to migrate control-system devices particularly I/O to the IEEE 1588 standard and time-based control solutions.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
