Improved implementation of phase logic routines

Logix Designer

with

PhaseManager

improves the implementation of equipment phases in

Logix 5000

controllers. Using OPC and the PLI, a phase is typically executed in a single relay ladder logic (RLL) routine that implements logic for all of the active states defined by the S88 standard. These active states include Stopping, Starting, Running, Holding, Aborting, and Restarting.

PhaseManager

supports a modularized approach to developing state routine logic by facilitating the development of each active state in its own routine.

PhaseManager

represents an equipment phase as a type of program in

Logix Designer

. Since programs can contain multiple routines, develop a separate routine for each active state required for the equipment phase. Developing separate routines for each active state also provides the ability to develop each routine in different programming languages.

Use other

Logix Designer

program features when developing equipment phase logic. These features include the ability to use timing diagnostics information, Max and Last Scan, for debugging equipment phases in

, and the ability to configure a fault routine for the equipment phase.
