Hardware Configuration - Multiple CDP-01’s
In the network below, the default SBPC-21-PB configuration is used multiple times to provide control to
multiple CDP-01’s. Each SBPC-21-PB is connected to a single CDP-01 creating a separate FifeNet
network for each CDP-01. Each SBPC-21-PB appears as both a FifeNet node and a Profibus node.
Notice the SBPC-21-PB Profibus address must be different for each SBPC-21-PB. The Profibus
address is set by rotary switches accessible via holes in the connector side of the SBPC-21-PB.

Software Configuration
Configurations have been created to match the single CDP-01 network shown in Figure 3-1. Since the
CDP-01 can have one, two, or three drives, a configuration has been created to match the parameters
present in each drive configuration. This prevents inefficient use of Profibus bandwidth for data that is
inapplicable. The three configurations are:

GSD File
A GSD file is provided with the SBPC-21-PB. Use this file when adding a new Profibus node to the network and
it will automatically set up the configuration for that network node. The table below indicates the quantity of data
transferred for single-, dual-, and triple-drive configurations.
