Introduction
This presentation will focus on
Variable Frequency Drives
controlled by a PLC via EtherNet/IP
communication. Benefits and
weaknesses are discussed as well
as the drive’s webpage and a
sample PLC setup comparing the
F7 drive to a PowerFlex 70.
Overview
Ethernet
•
Computer networking technology for local area networks (LAN)
•
Defined by IEEE 802.3 (wiring, signaling for physical layer, link layer, and
TCP/IP for transport and network layers)
EtherNet/IP
•
Uses same layers as Ethernet
•
Application layer is CIP (Common Industrial Protocol), which has the same
profile as traditional DeviceNet and ControlNet devices

Weaknesses
•
Security
•
Network design is critical
•
•

Example EtherNet/IP System
The following slides will outline the setup procedure for the system shown below. A comparison
will be made between setting up a Yaskawa F7 drive and an Allen Bradley PowerFlex 70.
Example EtherNet/IP System
For either drive, configure RS Linx by installing an EtherNet/IP driver as shown below. This
allows the PC to communicate over the EtherNet/IP network.
Either
Drive
Example EtherNet/IP System
To begin implementing the example system, configure the I/O in RS Logix 5000. Start RS
Logix 5000 and begin a new project by selecting ->’File’ and ->’New’. Select the correct
PLC/Controller and system descriptions for the example system being created.
Either
Drive
Example EtherNet/IP System
To add either drive to the I/O configuration, refer to the I/O configuration folder in the project
tree and highlight the EtherNet/IP port used in the project. In this case, the EtherNet/IP port is
the Local EtherNet/IP port on the 1769-L32E controller. Right click to add a new I/O module to
the project (in this case, a drive). The controller must be offline in order to add and\or
configure I/O devices.

Example EtherNet/IP System
To add a PowerFlex
70 drive to the PLC,
select it from the
Drives menu tree in
the New Module
dialog box.

Drive
Example EtherNet/IP System
When the PowerFlex 70 drive is selected, a dialog box is displayed, which requires a name
and the drives IP address.

To add an F7 drive to
the PLC, select the
Generic Ethernet
Module from the
Communications menu
tree in the New Module
dialog box.
.
F7
Drive
Example EtherNet/IP System
When the Generic Ethernet Module is selected, a dialog box is displayed, which requires a
name, IP address, and the assembly instances that will be used to communicate with the
drive. In this example, we will install the variable frequency drive (VFD) profile standard
assemblies output ‘21’ and input ‘71’, along with the default setting of ‘1’ for the configuration
assembly.

The PowerFlex 70 drive requires 3 rungs of logic to send a Speed Reference and Start/Stop
signals to the drive.

The F7 drive requires 2 rungs of logic to send a Speed Reference and Start/Stop signals to
the drive.

The following is a summary of setting up the two EtherNet/IP systems:
Adding a New I/O Module (drive)
•
Task is essentially identical. F7 requires the setting of the input and output assemblies
to be used.
“Tag” Descriptions of I/O Points
•
Both drives populate the I/O list in the PLC. The PowerFlex 70 has better generic tags. However,
most programmers will want to add custom “tags” to either drive to give the I/O specific meaning to
the machine and application.
PLC Ladder Logic
•
Task is essentially identical. PowerFlex 70 requires 3 rungs to the F7’s 2.
