PACSystems Control System Overview

The PACSystems controller environment combines performance, productivity, openness
and flexibility. The PACSystems control system integrates advanced technology with
existing systems. The result is seamless migration that protects your investment in I/O
and application development.
1.2.1

Programming and Configuration

PAC Machine Edition programming software provides a universal engineering
development environment for all programming, configuration and diagnostics of
PACSystems. A PACSystems CPU is programmed and configured using the programming
software to perform process and discrete automation for various applications. The CPU
communicates with I/O and smart option modules through a rack-mounted backplane. It
communicates with the programmer and/or HMI devices via the Ethernet ports or via the
serial ports COM1 and COM2 using Serial I/O, or Modbus RTU slave protocols.
1.2.2

Process Systems

PACSystems CPUs with firmware version 5.0 and later support PACProcess Systems (PPS).
PPS is a complete, tightly integrated, seamless process control system using PACSystems,
PACHMI/SCADA, and PACProduction Management Software to provide control,
optimization, and performance management to manage and monitor batch or
continuous manufacturing. It delivers the tools required to design, implement,
document, and maintain an automated process. For information about purchasing PPS
software, refer to the Support website.
