Installing the Adapter in a DPI External Comms
Kit (20-XCOMM-DC-BASE)
This chapter provides information on using 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 software tools
(DriveExplorer, DriveExecutive, etc.), data collection, etc.
•
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.
Important: Due to inherent operating limitations, the adapter cannot be
used with the kit’s I/O board option (20-XCOMM-IO-OPT*).
