MELSEC iQ-F and MELSEC-F Standards Display Change Technical Bulletin

This technical bulletin announces the addition of standards display markings (initially as stickers, later changed to laser printing) for various MELSEC iQ-F and MELSEC-F series models, including communication boards, expansion boards, memory cassettes, batteries, display modules, holders, and simulation input switches. The change, effective from October 2021 onward with subsequent display method updates in 2022 and 2024, has no impact on product specifications, performance, functions, or external dimensions.
