SNAP PAC R-Series Controllers User's Guide

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 groov EPIC edge programmable industrial controller or 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.

This user's guide covers the following SNAP PACs:

• SNAP-PAC-R1
• SNAP-PAC-R1-B [OBSOLETE]
• SNAP-PAC-R2 [OBSOLETE]

Guide to Networking SNAP PAC Products

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.

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 using wired Ethernet networks and wireless LANs, both within your facility and over the internet.

Using IEEE Floats in Opto 22 Products

While computers, CPUs, and electronic devices store numbers in binary format, most often they represent real numbers as floating point numbers, or floats. For example, in industrial automation applications, all analog values read from an I/O unit are floats.

This document describes how the IEEE 754 standard for floats is used in Opto 22 products, including groov RIO, groov EPIC, and SNAP PAC systems.

Application Brief: Perceptive Controls

Smaller water and wastewater treatment districts often have difficulty funding SCADA systems to monitor their operations as required. In addition, remote and rural equipment sites are much more difficult to connect. Wireless communication can fail due to terrain, while cellular communication can be cost prohibitive.

Recognizing the needs of smaller water and wastewater treatment plant operators, systems integrator Perceptive Controls decided to develop a cloud-based SCADA system to reduce costs and provide operators with the data they need.

Read about the problems involved in building the system and the ways Perceptive Controls approached solutions in this Opto 22 application brief.

SNAP PAC REST API and the Internet of Things - for OT Professionals

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 physical "things" to computer networks where it can be used?

This technical paper describes that pathway for OT (operational technology) professionals—automation professionals. It describes the kinds of data you may be asked to provide and why. It explains how data from physical "things"—especially existing sensors and actuators that have no IoT capabilities built in—can be securely communicated to company computer networks, without disturbing control networks.

The paper also explains concepts important to any IoT strategy, like encryption and authentication, and introduces a new method to achieve the IoT results you need now, without requiring a complex chain of conversion hardware and software.

Learn about the REST API and the IoT from an information technology (IT) professional's standpoint in the companion tech note, SNAP PAC REST API and the Internet of Things - for IT Professionals.

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.

Case Study: Automated Interface Solutions

Systems integrator Automated Interface Solutions (AIS) used the SNAP PAC System to solve a problem for one of its large customers, a manufacturer of polypropylene film.

Part of the company’s manufacturing process used older Measurex and Foxboro systems, tied by custom software to an Allen-Bradley® ControlLogix® PLC. Parts were becoming difficult to get and the custom software was expensive to change.

AIS installed the SNAP PAC System to replace the older hardware. Opto 22 PACs communicate natively with Allen-Bradley PLCs using the EtherNet/IP protocol. AIS worked with its customer to define all of the process control data it wanted the A-B system to have access to, and then made that data available within the shared memory of the Opto 22 PACs.

In addition, the SNAP PAC System sends data via OPC to the company’s Wonderware® Intouch® HMI, which displays real-time information on scanners, indicates die bolt positions (on or off), roll lengths and averages, and other statistics. Data transfer is accomplished via OPC, and more than 6,400 I/O tags are passed through to the HMI without issue.

Case Study: Bureau of Reclamation

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.
