Chapter 8 EtherNet/IP Network
Devices Included in the Node Count
Any EtherNet/IP devices that you add to the module configuration section are counted toward
the controller node limit. The following are examples of devices that must be counted:
• Kinetix 5100 Motion Drives
• PowerFlex 520-series Adjustable Frequency AC Drives
• Third-party devices that are configured as generic devices
Devices Excluded from the Node Count
When you calculate the EtherNet/IP node limitation of a controller, do not count devices that
exist on the EtherNet/IP network but are not added to the Module configuration section.
The following devices are not added to the module configuration section and are not counted
among the number of nodes:
•Computer
• Devices that are the target of MSG Instructions but were not added to the module
configuration section
• Standard Ethernet devices with which the controller communicates through a socket
interface

shows nodes in the module configuration.

How to Add PowerFlex 520-
series and Kinetix 5100
Drives over EtherNet/IP
Micro850 (2080-L50E) and Micro870 (2080-L70E) controllers support predefined tags in both
PowerFlex 520-series drives and Kinetix 5100 drives. All other EtherNet/IP devices use the
generic profile.
When a PowerFlex 520-series drive or Kinetix 5100 drive is configured for I/O Mode operation
and is used with Connected Components Workbench software, the use of predefined user-
defined function block (UDFB) motion instructions provides an easy way to program your
simple motion control application on Micro800 controllers with Class 1 connectivity feature.
For instructions on where to download the UDFB files, see Download the User-defined Function
Block Instruction Files on page 144.
Applies to these controllers:
Micro850 (2080-L50E only)
with firmware revision 21.011 or later
Micro870 (2080-L70E only)
with firmware revision 21.011 or later
IMPORTANT Induction and linear motors are not supported with the UDFB.
