SHEET guidelines
•
The sheets in the routine appear in order in the export file. Each
sheet section contains all the drawing elements and wires for
that sheet.
•
The sheet number is stored in a comment at the beginning of
the sheet for reference only. On import, sheet numbers are
assigned based on order in the file, not on the number in
the comment.
• The sheet name is stored as an attribute because it is optional.
• Input references, blocks, output references, special drawing
elements, and wires are contained within the sheet. On export,
the elements appear in the order shown. On import, elements
can be interspersed in the file.
• WIRE and FEEDBACK_WIRE statements must appear after all
the other components.
• Be careful when copying and pasting function block
components within an import/export file. Each component
within a sheet must have a unique ID number within that sheet.
