Figure 12.24 - Operation Details Screen
OPERATION SELECT
Use to select the logical function desired for the rung in question.
Operations are defied as either inputs or outputs. A rung can have
multiple inputs (logical operations) that it evaluates, but a rung can
only have a single output. The first five vertical columns of a rung
are designated for inputs, while the left-most column holds the
single output. The editor only allows selection of the operation
“type” that is appropriate for a given column. Clicking the Operation
Select button will bring up the Contact Selection screen.
