Configure PhaseManager
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.

PhaseManager Terms
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.
