Using the Adapter in a DPI External Comms Kit
(20-XCOMM-DC-BASE)
This chapter provides information and examples that explain how to use the
adapter in a DPI External Comms Kit (20-XCOMM-DC-BASE).
The adapter is typically installed in the internal communication slot on the
PowerFlex 7-Class drive. However, an externally-mounted adapter may be
desired when:
• The PowerFlex drive is already connected to an existing network, such as
Remote I/O, and a second network is desired for a DriveExplorer or
DriveExecutive software tool, data collection, and so forth.
• The PowerFlex drive is remotely located next to some I/O devices that
also need to be networked. The DPI External Comms Kit has an option
slot for general-purpose network I/O that a controller can use. Both the
drive and I/O devices are handled as one node on the network to reduce
the network node count.
Installing the Adapter The adapter can be installed in a DPI External Comms Kit.
