Information technology — Open systems interconnection — Part 1: Object identifier resolution system
This document specifies the OID resolution system, including the overall architecture and a DNS-based resolution mechanism.
It specifies the means for inserting any application-defined information associated with an OID node into the DNS (see clause 6) and the means of retrieval of that information using the ORS (see clause 7).
It does not restrict the number of applications it can support.

IEC 61158-3-4:2023 provides common elements for basic time-critical messaging communications between devices in an automation environment. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window…
