Guide to Networking Opto 22 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, 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.

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.

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.

SNAP PAC REST API and the Internet of Things - for IT 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 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.

Edge Computing in Industrial Automation

Successful industrial internet of things (IIoT) 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 to achieve these IIoT goals, 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 IIoT.

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

Case Study: Hong Kong Power Plant (Chinese)

This document is written in Chinese.

The Lamma Power Station in Hong Kong is using Opto 22 SNAP PAC standalone controllers to control heat, pressurization and other critical processes. The Opto 22 PACs connect to weigh scales, conveyors, pressure transducers, and thermocouples to ensure that the coal burning operations taking place at Lamma are executed safely and optimally.

For example, analog I/O modules wired to scales measure the weight of the coal prior to its delivery to the furnaces and sends these figures to the controller. Based on these readings—and whether they're low or high—the controller then instructs the conveyors delivering the coal to the furnaces to speed up or slow down appropriately, so the furnaces generate the proper amount of heat needed to spin turbines that produce the power.

At the same time, integrated circuit temperature derivative probes (ICTDs) connected to thermocouple analog input modules monitor the actual furnace temperatures, which are then used in PID calculations to regulate the temperature via analog output modules.
