Using 160-DN2 with DeviceNet Scanner
This chapter provides an overview of how to use the Bulletin 160-
DN2 Communication Module with a DeviceNet Scanner. Scanners
act as “Masters” on a DeviceNet Network for the I/O communication
with a 160-DN2 module. Scanners periodically send I/O messages to
a 160-DN2 module at a set frequency, and the module responds to
these I/O messages by sending status messages back to the scanner.
The scanner also allows a ladder logic program to configure and read
parameters from the Bulletin 160 SSC drive through special encoded
instructions called Explicit Messages.
This chapter contains information on:
•
How to create the EDS file for the 160-DN2 module.
•
How to set up the 160-DN2 module on DeviceNet.
•
How to select Input and Output Assemblies for I/O messaging.
•
How to set up a scanner (1756-DNB, 1771-SDN or 1747-SDN) to
work with the 160-DN2 module.
•
Sample ladder logic programs for ControlLogix, PLC-5, and SLC
controllers to control the Bulletin 160 SSC drive using I/O
messaging.
•
How to set up Explicit Messaging, and sample ladder logic
programs for ControlLogix, PLC-5, and SLC controllers to
execute Explicit Messaging.
Before continuing this chapter, we recommend that you read the
RSNetWorx for DeviceNet Getting Results Guide Online help
(installed with the software) and the DeviceNet Scanner Module
Installation Instructions Manual for the scanner being used.
Understanding the concepts in these manuals will be important to
using the information in this chapter.
This chapter includes examples for using the 160-DN2 module with a
1756-DNB Scanner/ControlLogix system, 1771-SDN Scanner/PLC-5
system, and 1747-SDN Scanner/SLC system.
Important: All examples in this chapter use a Bulletin 160 SSC
Series C preset speed drive, RSLinx Software (version 2.3x or
higher), RSNetWorx for DeviceNet Software (version 3.xxx or
higher), RSLogix Programming Software and, for ControlLogix,
Ethernet via the controller backplane.
