1 Scope
This document deals with the safety interface and control interface. It allocates
signals to a conformance class and/or conformance option. It describes the detailed
functions of each signal, describes and displays the timing interactions between signals
in flow charts and shows examples for safety matrices and safety-related functional
relationships.
This document defines three conformance classes and dedicated conformance options.
Classes and options consist of a number of signals to:
-
— allow a flexible adaptation of the interface(s) to a project-specific scope of functions and simultaneously;
-
— tie sets of signals tight enough to avoid unnecessary coordination efforts between suppliers of the machine tending systems and machines.
