Chapter 6
Explicit Messaging on DeviceNet™
Logic Controller Application
Example with Explicit
Messaging
This chapter is designed to demonstrate programming and explicit
message examples for both the SLC™ family of programmable
controllers and ControlLogix® family of programmable controllers.
The examples will show how to develop a program for simple control
and use a simple explicit message to retrieve data that is not
automatically acquired based on the input and output assembly of the
device. The user of the device can use this example as a guide in
developing, their own programs.
Below is the RSNetWorx™ view of the simple network used in this
example.
Figure 6.1 Simple Network
To assist in the development of the example the network will consist
only of the ArmorStart® and scanner. Therefore the only mapped
information in the scanner will be the ArmorStart. Refer to Chapter 5,
DeviceNet™ Commissioning for assistance in mapping.
