The PhaseManager option of RSLogix 5000 software gives you a state

model for your equipment. This chapter summarizes:

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 An equipment phase is similar to a program:

• You run the equipment phase in a task.

• You give the equipment phase a set of routines and tags.

An equipment phase is different from a program in these ways:

• The equipment phase runs by a state model.

• You use an equipment phase to do 1 activity of your equipment.

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. It's the actions or conditions of the

equipment at a given time.

The state model of an equipment phase is similar to 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

You code the transition conditions. When the conditions are true, the equipment phase

transitions the equipment to the next required state.

• makes sure that the equipment goes from state to state along an allowable path

PHASE tag When you add an equipment phase, RSLogix 5000 software makes a tag for the equipment

phase. The tag uses the PHASE data type.
