4-21 PLS Functions
Description This function allows you to divide output channels into groups, and assign operating
modes to the groups. Operating modes provide a powerful tool for relating output chan-
nel operation to sensor signals or other inputs. Incorporating modes into a control sys-
tem can greatly improve line efficiency, reduce scrap, and improve control accuracy
between machine sections at high speeds. See Section 6 for a complete explanation of
the uses and applications of operating modes.
Establishing Groups
When dividing outputs into groups, keep these rules in mind:
• Output channels are assigned to groups sequentially. Group 0 will begin with Output
0 and include the specified number of outputs; Group 1 will begin with the next output
and continue sequentially for its specified number of outputs; and so on. The last
group will automatically include all of the remaining outputs.
• You can establish as many as six groups or as few as one.
• Each group can operate in any of the six modes.
