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).
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.
