Optics and optical instruments — Ancillary devices for geodetic instruments — Part 2: Tripods
This document specifies the most important requirements of telescopic tripods for surveying instruments and the connection between instrument and tripod.
The requirements in this document enable instruments and tripods of different manufacturers to be joined to one another, without prejudicing their performance and their usefulness.
This document is applicable to tripods which are used for levels…

IEC 62541-7:2020 defines the OPC Unified Architecture (OPC UA) Profiles. The Profiles in this document are used to segregate features with regard to testing of OPC UA products and the nature of the testing (tool based or lab based). This includes the testing performed by the OPC Foundation provided OPC UA CTT (a self-test tool) and by the OPC Foundation provided Independent certification test…
IEC 62541-8:2020 is part of the overall OPC Unified Architecture (OPC UA) standard series and defines the information model associated with Data Access (DA). It particularly includes additional VariableTypes and complementary descriptions of the NodeClasses and Attributes needed for Data Access, additional Properties, and other information and behaviour.
The complete address space model,…
