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*).
