During the last SEMI Standards Information & Control North America Technical Committee Chapter Meeting in July 2021, several ballots from the Equipment Automation Software volume, or the E Series, passed procedural review and are awaiting publication. Chief among them are ballots for the Equipment Data Acquisition (EDA) Standards, which use the Freeze concept to identify a specific set of SEMI Standards.
Currently Freeze 2, which uses HTTP/1.1 with SOAP/XML, is available, while Freeze 3, which will use HTTP/2 with gRPC, is under consideration. In preparation for Freeze 3, several standards from the EDA Standards Suite have been revised to support HTTP/2 with gRPC and Protocol Buffers technology.
Summary of Changes
The Advanced Backend Factory Integration Task Force passed a line-item revision to SEMI E5, Specification for SEMI Equipment Communications Standard 2 Message Content (SECS-II). The revision establishes a consistent way for implementers to report the number of attempts to send an ItemPart in order to improve the functionality of Stream 21 Item Transfer messages.
Software Vendor Testing Session
In 2022, the SEMI Standards Diagnostic Data Acquisition (DDA) Task Force is planning to offer in-person and remote software vendor test sessions. EDA software implementers will work with peers to identify and resolve any interoperability issues. To learn more or to participate in the tests, please contact DDA Task Force co-leaders Albert Fuchigami (albert.fuchigami@peergroup.com) or Brian Rubow (brian.rubow@cimetrix.com).
