UNE EN IEC 62881:2018
This document addresses the setting and implementation of C&E tables for a consistent use in engineering activities. It is aiming for describing a simple format used to support a consistent exchange of information between different engineering disciplines involved in project or maintenance activities. The document defines the minimum requirements of the C&E table content, which is derived from existing design documents, e.g. P&ID or verbal descriptions. Out of scope of this document is the transfer of the relations defined in C&E tables into a functional or source code for the application programming of PLC/DCS. In addition, this document does not cover the implementation of complex and/or sequential logics at a dedicated automation platform, which will require additional stipulations to be done/ followed. Although C&E tables can be applied to describe safety relevant functions, it has to be observed, that the shown logic relations between sensors and actuators cannot satisfy the high demand of information as required by IEC 61511 section 10.3. Having this said, it needs to be understood, that C&E tables in fact may be used to document the fault reactions of the plant equipment and therefore may be used as reference point for the necessary safety verifications to be applied.
