10 The SoftLogix Motion Control System
Developing a Motion
Control Application
Program This section provides an introduction to concepts used in developing
application programs for motion control. These concepts include:
• Application program development
• The MOTION_INSTRUCTION tag
• Motion status and configuration parameters
• Modifying motion configuration parameters
• Handling motion faults
Application Program Development Developing a motion control application program involves the following:
The MOTION_INSTRUCTION Tag The controller uses the MOTION_INSTRUCTION tag (structure) to store
status information during the execution of motion instructions. Every motion
instruction has a motion control parameter that requires a
MOTION_INSTRUCTION tag to store status information.
