Target B. This action places a branch around the XIO instruction.
You may continue to add more branches to the rung or place instructions in the
branch you just created.
Deleting an Instruction or Branch
When you are editing a ladder program, you may want to delete an instruction,
move it, or copy it to one or more locations. The same is true for rungs and the
instructions in branches. If you choose to delete an instruction, the following
message appears:
CAUTION: REMOVING DATA REFERENCES LEAVES
DATA/FORCES IN THEIR LAST STATE .
The caution informs you that data/forces associated with the instruction is in its last
state and will remain so after you delete the instruction. This can cause incorrect
program operation if this data is associated with other instructions.
Deleting and Undeleting Rungs
When deleting and undeleting rungs, the same caution message is displayed on the
message line. Use the [F6], Delete Rung or [F7], Undelete Rung function keys.
