This part of IEC 61175 is applicable to all types of signals within an industrial system, installation and equipment and industrial products. It deals with the information aspect of signals and not with their physical implementation. This first edition cancels and replaces the second edition of IEC 61175 published in 2005 and constitutes a technical revision. It includes the following changes: an improved description of the principles for use and a strict separation between the physical aspect of a signal and its associated information, focusing on the latter.
It has the status of a horizontal standard in accordance with IEC Guide 108.
