This user's guide shows you how to install and use Opto 22's SNAP PAC R-series programmable automation controllers. SNAP PAC R-series controllers are on-the-rack industrial controllers. Each controller monitors and controls a wide range of devices and equipment wired to the I/O on its own rack and on distributed racks equipped with SNAP PAC EB-series brains. Alternatively, the R-series controller can be used as a slave to a larger, SNAP PAC S-series standalone industrial controller.

SNAP PAC controllers are programmed with PAC Control Basic or PAC Control Professional, Opto 22's flowchart-based development software, which is part of the PAC Project software suite.

Toyo Tanso USA manufactures a fine grade of graphite called isotropic graphite, and the company also provides graphite-related silicon carbide surface treatments to customers.

The batch automation process systems used to perform these surface treatments are in a busy, tough industrial setting. The multiple vessels involved in the process each require different specializations and careful management.

To control the vessels, Toyo Tanso needed a rugged control system with plenty of I/O options—and one that could be easily programmed and deployed.

Networking can be a complex subject. This guide tries to reduce the complexity by providing guidelines for how you might set up communications between your computer or mobile device and your SNAP PAC control system, including groov.

The goal is for you to be able to monitor and control your system from anywhere you need to, either inside your facility or outside it. It's possible to do this because Opto 22 control systems are built on standard protocols such as TCP and UDP over IP, which are the same protocols used by off-the-shelf computers, routers, and the Internet.

This guide shows you how to communicate with Opto 22’s SNAP PAC controllers and groov using wired Ethernet networks and wireless LANs, both within your facility and over the Internet.

This guide shows you how to use PAC Manager, part of the PAC Project Software Suite, to assign IP addresses, configure I/O, and inspect and maintain Opto 22 SNAP PAC hardware.

This white paper explores some important features of programming software for a programmable automation controller (PAC).

Successful Internet of Things (IoT) applications send data from systems that monitor and control the physical world to information technology (IT) data processing systems. There the data can be analyzed and the results used to improve business capabilities: better inventory management, better predictive maintenance, reduced asset downtime, and much more.

But first we need to solve 3 problems: how to connect the physical world to the IT world, how to handle the huge masses of data that physical systems produce, and how to efficiently structure the IoT.

This white paper explores these problems and how edge computing can help solve them.

The U.S. Bureau of Reclamation constructs dams, power plants, and canals, and delivers water to more than 31 million Americans. The Bureau also operates the Leadville Mine Drainage Tunnel (LMDT), which drains off and treats water from the local mining district so it can be safely discharged into the Arkansas River.

At the LMDT, the Opto 22 SNAP PAC System is used to monitor water levels, remove metals, adjust the water’s pH, reduce water turbidity, and otherwise treat the water before releasing it—cleaner even than everyday drinking water. More than 2500 I/O points are monitored, controlled, and alarmed.

What's in North Dakota that's as bright as the city of Chicago in the nighttime sky? It's flare gas from oil fields, a waste stream going up in smoke.

Pioneer Energy is changing that waste into resources, with their Mobile Alkane Gas Separator (MAGS). Mounted on a trailer, the complete system can be trucked to a well site, installed in 24 hours, and remotely monitored.

This case study explains how the system processes flare gas and how it is controlled and monitored.

Watch the video case study, too.

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."

SNAP PAC controllers manufactured in November 2008 and later have a microSD card slot in the top of the controller’s case.

Behavior for the microSD card has changed since the first release. This technical note describes behavior with controller firmware versions older than 9.0.

If you are running controller firmware 9.0 or newer, use instructions in the controller user’s guide; do not use this technical note.

We’ve all heard about the Internet of Things (IoT) and its promises: bringing useful data directly to people who make business decisions, and enabling machines to communicate with each other and make decisions for human benefit.

But how does the IoT actually work? How does the data get from inside these machines to computer networks where we can use it?

This technical paper describes that pathway for IT (information technology) professionals, explaining how physical "things" communicate, what kinds of data in them might be useful, and the current barriers to getting that data—especially from existing sensors and devices that have no IoT capabilities built in.

The paper also describes a new method to cut through those barriers and achieve the IoT results you want now.

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.
