适用范围: IEC 62026-3:2014 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two conductor pairs within one cable - one of these pairs provides a differential communication medium and the other pair provides power to the devices. This part establishes requirements for the interoperability of components with such interfaces. This third edition of IEC 62026-3 cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. The main changes with respect to the previous edition are the followings: - specification of group 4 messages (5.1.2); - clarifications on messaging protocol (5.2); - addition of I/O multicast poll messages (5.5.2 and 5.5.8); - clarifications on slave behaviour (5.5.4 and 5.5.9); - clarifications on physical layer (transceiver) in 5.7; - miscellaneous corrections/clarifications on cable (8.2); - clarifications on EMC testing (9.2.10) and logical testing (9.3).
