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
Modbus/TCP Protocol
Guide,
form #1678, 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.
