controllers. PAC Display Professional can also connect to Ethernet-based FactoryFloor controllers running
OptoControl strategies.
OptoOPCServer
is a fast, efficient OPC 2.0-compliant server for communicating with many Opto 22 products,
including SNAP PAC controllers and I/O units, plus legacy Opto 22 Ethernet-based controllers and I/O. Using
OptoOPCServer, you can consolidate data from all these Opto 22 systems into the OPC client software of your
choice, such as third-party HMI and data acquisition packages, and custom software applications you create
with tools such as Visual C++
®
.
OptoDataLink
is a software application that makes it easy to share data from the SNAP PAC System with
commonly used databases, including Microsoft SQL Server, Microsoft Access, and MySQL, as well as text files.
The I/O points and strategy variables already created in your PAC Control strategy are automatically available
for OptoDataLink to use for data exchange.
PAC Manager
is a utility application for assigning IP addresses to SNAP PAC controllers and brains, reading or
changing basic controller configuration, and configuring and testing I/O.
For Developers: SNAP PAC REST API
If you’re a developer who’d like to use PAC Control strategy tags in communications with other devices, the
Opto 22 SNAP PAC REST API is a secure and powerful way to do just that. The API is available in SNAP PAC
R-series and S-series controllers with PAC firmware R9.5a and higher. To configure https access to your PAC’s
RESTful server and learn how to call the API, visit
ABOUT THIS GUIDE
This guide shows you how to install and use SNAP PAC R-series controllers. This guide assumes that you have
some familiarity with TCP/IP and Ethernet networking, and also with wireless networking if you are using
Wired+Wireless models. If you are not familiar with these subjects, we strongly suggest you consult
commercially available resources to learn about them before attempting to install or use SNAP PAC R-series
controllers.
If you are using Modbus/TCP for communicating with SNAP PAC R-series controllers, this guide assumes that
you are already familiar with Modbus/TCP. See the
(
form1678) for additional
information.
If you are using EtherNet/IP for communication, you should already be familiar with EtherNet/IP. See the
EtherNet/IP for SNAP PAC Protocol Guide
(form 1770).
The following sections are included in this user’s guide:
—information about the guide and how to reach Opto 22 Product Support.
—quick-start steps to get SNAP PAC R-series controllers up and running quickly.
—conceptual information on networking and communicating with SNAP
PAC R-series controllers; descriptions of features, capabilities, and specifications for SNAP PAC R-series
controllers.
Chapter 4: Maintenance and Troubleshooting
—assigning and changing IP addresses, resetting the
controller to factory defaults, using the microSD slot, upgrading firmware, and tips for resolving difficulties you
may encounter while working with SNAP PAC R-series controllers.
Appendix A: SNAP Mounting Racks and Power Supplies
— wiring diagram examples for assembling your
SNAP PAC R-series controller, SNAP PAC rack, and power supply.
