Using the 160-PD1 on Profibus
The purpose of this chapter is to provide an example of the steps
necessary to use the 160-PD1 on a Profibus network. As Profibus is a
3
rd
party network, we will be using the SST-PFB-SLC scanner to act
as a master for Profibus, residing in an A-B SLC500 rack.
The SST scanner sends I/O messages periodically to a Bulletin
160-PD1 to start and stop the drive and control its speed. Additionally
the Bulletin 160-PD1 responds to these I/O messages by sending
status messages and speed feedback back to the scanner. In this way
the ladder logic program in the A-B SLC500 PLC can control the
drive.
The Bulletin 160-PD1 also supports a Profibus telegram which can be
used to configure or read parameters from the drive.
This chapter contains the following information:
• How to create a Profibus network configuration frame.
• How to configure the SST-PFB-SLC scanner for use in a SLC
rack.
• A sample ladder logic program to control the Bulletin 160 SSC
using I/O messaging.
• A description of the Profibus telegram.
• A sample ladder logic program to execute the telegram.
The SST-PFB-SLC scanner for the SLC500 is used in the examples
in this manual. However the concepts demonstrated in the examples
apply to any Profibus master.
Required Tools The following tools are needed to complete this chapter.
• Bulletin 160 series C or higher, equipped with a 160-PD1
Profibus communication module
• SLC500 processor with a digital input card to issue start & stop
commands.
• SST-PFB-SLC scanner card, SST Configuration Tool and null
modem cable.
