TS EN 60848

TS EN 60848 concerns the GRAFCET specification language used to describe sequential function charts. In practical automation and control engineering, this kind of language provides a structured way to represent how a process advances step by step, which conditions trigger transitions, and how alternative or parallel sequences are organised. It is a formal notation for making sequential behaviour easier to define, read, and communicate.

How GRAFCET relates to sequential function charts

GRAFCET is a well-established method for modelling sequential control logic, and it is closely associated with Sequential Function Charts (SFC). In general technical terms, such languages separate the behaviour of a machine or process into steps, actions, and transitions so engineers can describe control logic in a consistent and human-readable form. This is especially useful when a system has state-based behaviour, conditional progression, and branches that must be documented clearly.

Why the subject matters in engineering documentation

A GRAFCET-based notation helps reduce ambiguity that can arise from informal narratives or loosely drawn flow diagrams. Concepts such as step, transition, action, and parallel branch make it easier to show when a control system moves forward, when it waits, and how concurrent sequences interact. In general technical practice, this supports design reviews, specification writing, implementation, and maintenance by giving teams a common reference for sequential behaviour. TS EN 60848 focuses on this specific specification language for expressing sequential functions.

• Structured representation of automation and control logic
• Clear modelling of process progression through steps and transitions
• Support for sequential and parallel behaviour in one notation
• Shared technical language for machines, processes, and control software
