The VLT® EtherNet/IP MCA 121 option
oers plug and play connectivity to
EtherNet/IP based networks, such as
Rockwell PLC systems, via the Com­mon Industry Protocol (CIPTM) proto­col.

The option can handle a single Ether­Net/IP Class 1 connection with a
Requested Packet Interval (RPI) of 1 ms
in both directions. This makes it one of
the highest performing EtherNet/IP
devices in the market.

The option features a built-in 2-port
switch, facilitating traditional line
network or Device Level Ring (DLR)
topology. The DLR in the MCA 121 is
Beacon based, to achieve the fastest
fault detection with recovery time
down to 3 ms. These topologies
eliminate the need for the complex
cabling and expensive industrial
Ethernet switches, which are used in
star topology.

Other features

n Built-in web-server for remote

diagnosis and reading out basic drive
diagnosis.

n An E-mail notificator can be config-

ured for sending an e-mail message
to one or several receivers, if certain
warnings or alarms occur, or have
cleared again.

n Add On Instruction (AOI) that reduces

the time, effort and cost involved in
development of the PLC program.
The AOI contains a list of pre-defined
tags used to control the drive

n Swift integration into the PLC

configuration tool via an EDS file

Application protocols

n EtherNet/IP (Industrial Protocol) for

controlling and parameter settings

n

CIP (Common Industry Protocol) For

communication to the PLC

n

HTTP (Hypertext Transfer Protocol)

for diagnosis via build-in web server

n

SMTP (Simple Mail Transfer Protocol)
for e-mail notification

n

DHCP (Dynamic Host Configuration

Protocol) automatic IP address

configuration

n

Supports connection to
VLT® Motion Control Tool MCT 10
over TCP/IP

Connectivity to EtherNet/IP based networks

Requested Packet Interval (RPI) of 1 ms

Built-in web-server

E-mail noticator Noties if warnings or alarms occur

Two Ethernet ports with built-in switch

Based on CIP Protocol

Supports Device Level Ring (DLR) topology

Connects to Rockwell PLC-system via the
Common Industry Protocol (CIP

High performance

Remote diagnosis and reading out of
basic drive parameters

• Simple cabling

• No need for expensive switches or hubs

Reuse of PLC program when migrating from
DeviceNet to EtherNet/IP or supporting both
technologies.

A single fault in one of the Ethernet cables, or
one of the devices in the ring, will not lead to
loss of the communication to all devices.
