Ladder Logic Programming—

Including Reading Inputs

Chapter Objectives

Chapter 5 provides information needed to create the PLC, SLC, or
ControlLogix Ladder Logic program that the controller will use to
transmit control I/O and messages to and from the SCANport
product. In this chapter, you will read about the following:

Equipment and software needed to create either a PLC or SLC
ladder logic program.

PLC, SLC, and ControlLogix ladder logic programs.

Creating a PLC, SLC, or ControlLogix ladder logic program.

This chapter assumes you are familiar with the hardware components
and programming procedures necessary to operate DeviceNet and
SCANport devices, including the following:

PLC-5, SLC-500, or ControlLogix.

1771-SDN, 1747-SDN, or 1756-DNB scanner.

Ladder programming.

RSLogix5 (for PLC-5), RSLogix500 (for SLC-5/02 through SLC
5/05), and RSLogix 5000 (for ControlLogix).

You may need to refer to the documentation associated with these
products to create a ladder logic program.

Required Equipment

Before creating a ladder logic program for the PLC, SLC, or
ControlLogix, your PC must be:

Running RSLogix5 and RSLinx if using a PLC. Refer to
http://www.software.rockwell.com for more information on these
products.

Running RSLogix500 and RSLinx if using an SLC. Refer to
http://www.software.rockwell.com for more information on these
products.

Running RSLogix5000 and RSLinx if using a ControlLogix.
Refer to http://www.software.rockwell.com for more information
on these products.

Connected to and communicating with the DeviceNet network
using a 1784-PCD card, 1784-PCID card, 1784-PCID5 card, or a
1770-KFD adapter.
