2.4 Inserting Instructions into a Rung
Build a rung by using the mouse to drag and drop instructions from
an instruction palette and connect them together by drawing wires.
The program area is like a blank canvasāĊāyou drag instructions
from the instruction palettes and drop them in the program area. But
first, you must start a rung by dragging an instruction from an
instruction palette and dropping it very near the left power rail. To
help make inserting instructions easier, the insert cursor indicates
when and in which direction you can drop an instruction. See
section 2.1 for more information on starting a rung.
When dropped into the rung, the instructions indicate where you
can attach another instruction or wire. Contact instructions have
connections on either side, but coil instructions can only connect to
another instruction on the left side.
For instruction blocks like ADD, you can connect other instructions
to the longer lines. These longer lines attach to Boolean input and
output parameters.
An inserted instruction belongs to the rung above it if the newly
inserted instruction does not start a rung.
To insert instructions into a rung
Step 1.
Click on the Ladder Language toolbar button that
accesses the instruction palette you want to use.
The instruction palette appears.
Step 2. Point to the instruction you want to insert.
Step 3. Press and hold the left mouse button while dragging the
instruction into the program area.
Step 4. When the pointer is where you want the upperĆleft corner
of the instruction to be, release the left mouse button,
dropping the instruction into place.
If you drop an instruction very near another, the newlyĆplaced
instruction automatically connects to the one adjacent to it. Similarly,
you can insert an instruction between two instructions by simply
dragging it between the existing two.
Tip
If you frequently use the instruction on a toolbar palette, you may
want to turn the toolbar palette on. See Turning the Toolbars and
Palettes On and Off" in Appendix A.
Tip
If you delete or cut the first instruction of a rung, the left power rail
connection stays, indicating that you can insert a new instruction.
Insert the new instruction to the right of the left power rail connector.
Tip
You can move or copy one or more instructions from one rung and
insert them into another rung. See Moving Instructions" and
Copying Instructions" in the AutoMAx Ladder Editor online help.
