Introduction
This chapter explains how to configure PhaseManager.
Within RSLogix 5000 programming software, PhaseManager provides a
state model for your equipment.

PhaseManager Overview
PhaseManager lets you add equipment phases to your controller. An
equipment phase helps you lay out your code in sections that are
easier to write, find, follow, and change.

Term Description
Equipment phase • As with a program, an equipment phase is run in a task and is given a set of routines and tags.
• Unlike a program, an equipment phase runs by a state model and lets you do one activity.
State model • A state model divides the operating cycle of your equipment into a series of states. Each state is an instant in the
operation of the equipment, the actions, or conditions of the equipment at a given time.
• The state model of an equipment phase resembles that of the S88 and PackML state models.
State machine An equipment phase includes an embedded state machine that:
• calls the main routine (state routine) for an acting state.
• manages the transitions between states with minimal coding.
• makes sure that the equipment goes from state to state along an allowable path.
PHASE tag When you add an equipment phase, RSLogix 5000 programming software makes a tag for the equipment phase. The
tag uses the PHASE data type.
