Chapter 1 Getting Started
used in a linear or device-level ring (DLR) network topology. When using a star
network topology, either the ENET1 or ENET2 network port may be used. In
Adapter mode, the ‘Integrated Motion on the EtherNet/IP network’
functionality is not supported.
Tap Mode (only with PowerFlex 755 drives)
In the Tap mode, the option module operates like a gateway and functions similar
to the 1783-ETAP module. By connecting the supplied Ethernet cable between
the option module’s ENET3 network port and the embedded EtherNet/IP
adapter port on the PowerFlex 755 drive, the option module enables the
PowerFlex 755 drive to extend its I/O connection to a linear or device-level ring
(DLR) network topology. This also enables ‘Integrated Motion on the EtherNet/
IP network’ functionality supported by the PowerFlex 755 drive to be used with
these topologies.
Understanding Parameter
Types The option module has two types of parameters:
• Device parameters are used to configure the option module to operate on
the network.
Device parameters, when viewed with DriveExplorer or
DriveExecutive software, appear below the 20-750-ENETR listing in the
treeview in a separate Device Parameters folder. When viewed with the
20-HIM-A6 or 20-HIM-C6S HIM, these parameters appear in the DEV
PARAM folder.
• Host parameters are used to configure the option module Datalink transfer
and various fault actions with the drive.
Host parameters, when viewed
with DriveExplorer or DriveExecutive software, appear below the 20-750-
ENETR listing in the treeview in a separate Host Parameters folder. When
viewed with the 20-HIM-A6 or 20-HIM-C6S HIM, these parameters
appear in the HOST PARAM folder.
IMPORTANT Some Device parameters are not applicable when operating the option
module in Adapter mode while others are not applicable in Tap mode.
Therefore, these non-applicable parameters are labeled ‘Reserved’ in
the Adapter and Tap mode operation parameter tables in
Appendix B .
IMPORTANT When operating the option module in Tap mode, Host parameters are
not supported.
