Using 160-DN1 with DeviceNet Scanner
The purpose of this chapter is to provide an overview of the steps nec-
essary to use the Bulletin 160-DN1 with a DeviceNet Scanner. Scan-
ners act as “Masters” on a DeviceNet Network for the IO
communication with a Bulletin 160-DN1. Scanners send “IO” mes-
sages periodically to a Bulletin 160-DN1 at a set frequency, and the
Bulletin 160-DN1 responds to these IO 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
through special encoded instructions called Explicit Messages.
This chapter contains the following information:
• How to setup the 160-DN1 on DeviceNet.
• How to setup the 1747-SDN to work with the 160-DN1.
• A sample ladder logic program to control the Bulletin 160 SSC
using polled messaging.
• A description of Explicit Messaging.
• A sample ladder logic program to execute Explicit Messaging.
Before continuing this chapter, the user should have read the
DeviceNet Manager Software User Manual and the 1747-SDN
DeviceNet Scanner Module Installation Instructions Manual. Under-
standing the concepts in these manuals will be important to complet-
ing this chapter.
The 1747-SDN Scanner for the SLC 500 is used in the examples in
this manual, but the concepts demonstrated in the examples apply to
the 1771-SDN Scanner for the PLC 5 as well.
Important: The examples in this chapter reflect the following config-
uration: a Bulletin 160 SSC, Series B, preset speed model, with
P15 - [Interface Select] set to 0, Bulletin 160 SSC Interface, and
DeviceNet Manager software version 3.001.
