DIN EN 62026-1 VDE 0660-2026-1:2018-10

This Standard applies to interfaces between low-voltage switchgear, controlgear and controllers (e. g. programmable controllers, personal computers, etc.). It does not apply to higher level industrial communication networks that have become known as fieldbuses and are considered by IEC subcommittee 65C. The purpose of this series of standards IEC 62026 is to harmonize and define rules, components and requirements of a general nature applicable to industrial CDIs (controller-device interfaces). Those features of the various CDI standards which can be considered as general have therefore been brought together in this Part 1 of IEC 62026.
