Figure 2.
The PLS can be programmed by means of
Logic Programming equipment.
With Logic programming, the
AND/OR–EX-OR input connections
necessary to implement the desired logic
function are coded directly from the State
Diagram using the Program Tables on the
following pages.
In these Tables, the logic state or action of
all I/O, control, and state variables is
assigned a symbol which results in the
proper fusing pattern of corresponding
links defined as follows:
