Use the GuardPLC Controller as a Scanner

Introduction

Prepare the GuardPLC
Controller for Class 1
Scanner Connections

Make sure the GuardPLC controller resource has the EtherNet/IP
protocol added under the Protocols folder in the RSLogix Guard PLUS!
Hardware Management project tree. If it does not, see page

203

for

instructions on adding EtherNet/IP protocol to the project.

The GuardPLC controller’s scanner I/O assembly consists of two
buffers: one to store input data and the other to store output data.
When a new connection is opened from the GuardPLC controller to
an I/O module, the scanner input buffer receives data from the I/O
module and the scanner output buffer stores data that is sent to the
I/O module.

You must allocate enough space in both of these buffers to store the
corresponding data. You do this by creating signals in the Signal
Editor and assigning them to the scanner assembly. For detailed
information on defining signals by using the Signal Editor, refer to the
