Sequential Function Chart/Grafcet

With the SFC/Grafcet module, Automation Studio™ becomes a completely automated project specification environment. It is the tool of choice to implement SFC control structures according to the IEC 61131-3 international standard for PLC programming languages.

  • Design automated controls faster
  • Easily troubleshoot simple to large projects
  • Indispensable tool to ensure system commissioning
  • Helps train operations personnel and improves overall project quality

Design Automated Controls Faster

SFC/Grafcet is the method of choice to design structured automation controls. It brings a new dimension to building projects quickly and efficiently. SFC/Grafcet helps to easily design operation sequences and validates a project prior to its implementation. It complements project documentation by helping engineers, customers and maintenance personnel understand equipment operations (ISO1219-2 recommends the use of SFC/Grafcet for project documentation).

Trade Oriented Editor

This module offers special editing functions and features adapted to create SFC/Grafcet. Combined with the system design features, this provides a user-friendly and efficient environment that helps gain productivity.

SFC/Grafcet Code Imports/Exports

Automation Studio™ can import SFC/Grafcet codes either in XML or in Cadepa™ software format. It also allows you to export SFC/Grafcet into Siemens™ S7 PLC and XML format. AS a result, you can perform direct importations into the Siemens™ programming software. With the XML format, device specific compilers could create virtually any type of machine code.

A Structured Approach and a Powerful Tool

Although the interface is simple, there is more depth to this module than meets the eye. During the creation of an SFC/Grafcet, control elements can be used to implement fault management. SFC/Grafcet can also be “Forced” or “Frozen” during simulation. Sequence and step execution intervals can be defined and a higher hierarchy level can be exploited by defining macro steps from which entire control structures can be created.

Variable Data Listing

While entering commands, you have access to all available variables. The Variable Manager is used to create new variables and specify their data types and scope of use (local, internal, or global for the project).

Guided Mode

This module guides you when creating SFC/Grafcet elements and writing statements, which eases the writing process of correct syntax. Each time you insert an action or a transition, a configuration window indicates various commands with a description and definition. Online help is also always available.
