1. INTRODUCTION

Vacon NX frequency converters can be connected to Ethernet using an Ethernet fieldbus board

OPTCI.

The OPTCI can be installed in the card slots D or E.

Every appliance connected to an Ethernet network has two identifiers; a MAC address and an IP
address. The MAC address (Address format: xx:xx:xx:xx:xx:xx ) is unique to the appliance and cannot
be changed. The Ethernet board's MAC address can be found on the sticker attached to the board or
by using the Vacon IP tool software NCIPConfig. Please find the software installation at

www.vacon.com

In a local network, IP addresses can be defined by the user as long as all units connected to the
network are given the same network portion of the address. For more information about IP
addresses, contact your Network Administrator. Overlapping IP addresses cause conflicts between
appliances. For more information about setting IP addresses, see Section 3, Installation.

WARNING!

Internal components and circuit boards are at high potential when the frequency
converter is connected to the power source. This voltage is extremely dangerous
and may cause death or severe injury if you come into contact with it.

If you need further information related to EtherNet/IP, please contact [e-mail].

2.3 Ethernet

EtherNet/IP™ was introduced in 2001 and today is the most developed, proven and complete
industrial Ethernet network solution available for manufacturing automation. EtherNet/IP is a
member of a family of networks that implements the Common Industrial Protocol (CIP™) at its
upper layers. CIP encompasses a comprehensive suite of messages and services for a variety of
manufacturing automation applications, including control, safety, synchronization, motion,
configuration and information. As a truly media-independent protocol that is supported by hundreds
of vendors around the world, CIP provides users with a unified communication architecture
throughout the manufacturing enterprise.

Common use-cases of Ethernet – devices are ‘human to machine’ and ‘machine to machine’.
Basic features of these two use-cases are presented in the pictures below.

1. Human to machine (Graphical User interface, relatively slow communication)

Note! NCDrive can be used in NXS and NXP drives via Ethernet. In NXL drives this is not
possible.

2. Machine to machine (Industrial environment, fast communication)

2.4 Connections and Wiring

The Ethernet board supports 10/100Mb speeds in both Full and Half-duplex modes. The
boards must be connected to the Ethernet network with a shielded CAT-5e cable. Use a so­called crossover cable (at least CAT-5e cable with STP, Shielded Twisted Pair) if you want to
connect the Ethernet option board directly to the master appliance.
Use only industrial standard components in the network and avoid complex structures to
minimize the length of response time and the amount of incorrect dispatches.

More information on Ethernet can be found at www.odva.org.

3.1 Installing the Ethernet Option Board in a Vacon NX Unit

!

NOTE

MAKE SURE THAT THE FREQUENCY CONVERTER

IS SWITCHED OFF

BEFORE

AN OPTION OR FIELDBUS BOARD IS CHANGED OR ADDED!

A

Vacon NX frequency converter.

B

Remove the cable cover.

D

Install EtherNet/IP option board in slot

D or E on the control board of the
frequency converter. Make sure that the
grounding plate (see below) fits tightly in
the clamp.

E

Make a sufficiently wide opening for
your cable by cutting the grid as wide as
necessary.

F

Close the cover of the control unit and
the cable cover.

3.2 NCDrive

NCDrive software can be used with the Ethernet board in NXS and NXP drives.

NOTE! Does not work with NXL

NCDrive software is recommended to be used in LAN (Local Area Network) only.

NOTE! If OPTCI Ethernet Option board is used for NC Tools connection, like NCDrive, the OPTD3
board can not be used.

NOTE! NCLoad does not work via Ethernet. See NCDrive help for further information.

3.3 IP Tool NCIPConfig

To begin using the Vacon EtherNet/IP board, you need to set an IP address. The factory default IP
address is 192.168.0.10. Before connecting the board to the network, its IP addresses must be set
according to the network. For more information about IP addresses, contact your network
administrator.

You need a PC with an Ethernet connection and the NCIPConfig tool installed to set the EtherNet/IP
board's IP addresses. To install the NCIPConfig tool, start the installation program from CD or
download it from www.vacon.com website. After starting the installation program, follow the on-
screen instructions.

Once the program is installed successfully, you can launch it by selecting it in the Windows Start
menu. Follow these instructions to set the IP addresses. Select

Help --> Manual if you want more

information about the software features.

Step 1. Connect your PC to the Ethernet network with an Ethernet cable. You can also connect
the PC directly to the device using a crossover cable. This option may be needed if your PC does not
support Automatic crossover function.

Step 2. Scan network nodes. Select Configuration --> Scan and wait until the devices connected to
the bus in the tree structure are displayed to the left of the screen.

NOTE!
Some switches block broadcast messages. In this case, each network node must be scanned
separately. Read the manual under Help menu!

Step 3. Set IP adresses. Change the node’s IP settings according to the network IP settings. The
program will report conflicts with a red color in a table cell. Read the manual under Help menu!

Step 4. Send configuration to boards. In the table view, check the boxes for boards whose
configuration you want to send and select Configuration, then Configure. Your changes are sent to
the network and will be valid immediately.

NOTE! Only A-Z, a-z and 0-9 symbols can be used in the drive name, no special characters, or
Scandinavian letters (ä, ö, etc.)! The drive name can be freely formed using the allowed characters.

3.3.1

Update OPTCI Option Board program with the NCIPConfig Tool

In some cases it may be necessary to update the option board's firmware. Differing from other Vacon
option boards, the EtherNet/IP option board's firmware is updated with the NCIPConfig tool.

NOTE! The IP addresses of the PC and the option board must be in the same area when the software
is loaded.

To start the firmware update, scan the nodes in the network according to the instructions in section

7. Once you can see all nodes in the view, you can update the new firmware by clicking the

VCN

packet field in NCIPCONFIG 's table view on the right.
