SNAP PAC brains are powerful and versatile I/O and network communications processors. Designed primarily to work in distributed systems controlled by a SNAP PAC controller, SNAP PAC Ethernet brains can also be used as intelligent remote I/O for Allen-Bradley Logix-based PLC systems.
SNAP PAC brains provide local intelligence for functions such as latching, counting, thermocouple linearization, watchdog timers, and PID loop control.

SNAP PAC brains, one of the four components of the SNAP PAC System, provide I/O processing and network communications for your distributed SNAP PAC System. SNAP PAC Ethernet brains can also be used as intelligent remote I/O in an Allen-Bradley Logix-based PLC system.
This guide shows you how to install and use all SNAP PAC brains: wired Ethernet, Wired+Wireless, and serial.

This document shows examples of system architecture for PC-based I/O control systems and lists Opto 22 products that work together for PC-based control.
System examples include:
- Ethernet systems using SoftPAC, a software-based programmable automation controller programmed with PAC Control
- Ethernet systems using the OptoMMP protocol
- Direct control of I/O using no I/O processor (no brain)
- Serial control using a brain and the mistic or Optomux protocol
- High-speed control using the Pamux protocol

This guide is for programmers who are writing custom applications to communicate with Opto 22 memory-mapped devices. These devices include SNAP PAC controllers and SNAP PAC EB and SB brains; G4EB2 brains; SNAP Ultimate, SNAP Ethernet, and SNAP Simple I/O; E1 and E2 brain boards, and SNAP-LCE controllers.
The guide describes how to use the IEEE 1394-based OptoMMP memory-mapped protocol for programming. The guide also contains the complete memory map for all Opto 22 memory-mapped devices.
NOTE: This guide replaced previous individual programming guides for SNAP Ultimate I/O (form #1312) and SNAP Ethernet I/O (form #1227). This document was formerly called the "SNAP Ethernet-Based I/O Units Protocols and Programming Guide."

This document is the Legacy Edition of the PAC Manager User's Guide. It includes information about both SNAP PAC hardware and older hardware.
Use this guide if you are using any legacy hardware (SNAP Ultimate, SNAP Ethernet, and SNAP Simple I/O, E1 and E2 brain boards) with PAC Manager.
If you are using SNAP PAC controllers and SNAP PAC brains only, use form #1704 instead of this guide.

This white paper explores the use of intelligent remote I/O in industrial automation systems. Employing a distributed architecture, rather than centralized control, offers three advantages: minimizing single points of failure, spreading the load, and maximizing scalability.
The paper details applications that could be made more efficient by using built-in functions offered by intelligent remote I/O. It also gives a specific example of how distributed intelligence could be used in a PLC system.

Ballarat Health Services in Victoria, Australia, is a major health care organization comprising two hospitals, convalescent homes, psychiatric services, six nursing home hostels, and rehabilitation centers. Ballarat upgraded from older Opto 22 M4 controllers and now uses Opto 22's SNAP PAC System for equipment automation and building management. Their broad set of applications includes remote monitoring, alarming, process and discrete control, and data acquisition for performance optimization, energy management, and regulatory compliance reporting.

This technical note introduces SNAP I/O (brain, mounting rack, and I/O modules) for Allen-Bradley industrial PLC systems that use EtherNet/IP, including ControlLogix, CompactLogix, and MicroLogix.
The technical note briefly presents communication concepts, such as implicit and explicit messaging, and describes how to use implicit messaging to communicate with an A-B RSLogix-based PLC system.
