Sequencer Instructions
Sequencer instructions are used to control automatic assembly machines
or processes that have a consistent and repeatable operation. They are
typically time based or event driven.
Use the sequencer compare instruction to detect when a step is complete;
use the sequencer output instruction to set output conditions for each
step. Use the sequencer load instruction to load data into the sequencer
file.
The primary advantage of sequencer instructions is to conserve program
memory. These instructions monitor and control 16 (word) or 32 (long
word) discrete outputs at a time in a single rung.
You can use bit integer or double integer files with sequencer
instructions.
