6.3.1 Drawings (DWGs)
User programs are managed in units of programming called drawings. Each drawing is identified by a drawing
number (DWG No.). These drawings serve as the basis of user programs.
The drawings include parent drawings, child drawings, grandchild drawings, and operation error drawings.
Besides the drawings, there are functions that can be freely called from each drawing.
• Parent Drawings
Parent drawings are executed automatically by the system program when the execution condition is
established. See the following table for execution conditions.
• Child Drawings
Child drawings are executed by being called from a parent drawing using the SEE instruction.
• Grandchild Drawings
Grandchild drawings are executed by being called from a child drawing using the SEE instruction.
• Operation Error Drawings
Operation error drawings are executed automatically by the system program when an operation error
occurs.
• Functions
Functions are executed by being called from a parent, child, or grandchild drawing using the FSTART
instruction.
• Types and Priority Levels of Drawings
Drawings are classified by the first character of the drawing number (A, I, H, L) according to the purpose of
the process. The priority levels and execution conditions are as shown in the following table.
