Before You Begin

What This Chapter Contains

This chapter provides an overview of communication between a 
PLC-5 processor and DeviceNet devices via a 1771-SDN module. The 
data tables and the RSNetWorx for DeviceNet screens and windows 
used to configure the data tables are also described.

The following table identifies what this chapter contains and where to 
find specific information.

What You Need to Know

Before configuring your 1771-SDN scanner module, you must 
understand:

•

the data exchange between the PLC -5 processor and DeviceNet 
devices through the 1771-SDN module

•

user-configurable 1771-SDN module data tables

•

the role of RSNetWorx for DeviceNet software
