2.1.1
Defining the Horizontal and Vertical Grid Limits Per
Rung
You can define limits for the size of the grid used by the Editor to lay
out each rung. This lets you make sure that your program printouts
fit on your preferred page size without the rungs being split up.
Relay instructions occupy a grid space of 1 x 1. More complex
instructions occupy at least 3 units horizontally by 2 to 8 units
vertically.
The default grid size per rung is 40 horizontal units by 24 vertical
units, which is also the maximum grid size per rung.
The Editor lets you place instructions outside the grid limits. Rungs
that exceed either limit cause a warning to be displayed during a
verify operation. The limits you set are checked only when you
perform a verify operation.
To define the horizontal and vertical grid limits per rung
Step 1.
From the Tools menu, choose Options. A tabbed dialog
box is displayed.
Step 2.
From the General tab, locate the Per Rung Instruction
Grid group box.
Step 3.
Enter the desired values for the Horizontal and Vertical
fields. The Editor uses these new values for all
subsequent programs you open.
Step 4.
Click OK to accept the new grid size.
