Connectivity to EtherNet/IP based networks
Connects to Rockwell PLC-system via the
Common Industry Protocol (CIP
Requested Packet Interval (RPI) of 1 ms
Remote diagnosis and reading out of
E-mail noticator Noties if warnings or alarms occur
Two Ethernet ports with built-in switch
• No need for expensive switches or hubs
Reuse of PLC program when migrating from
DeviceNet to EtherNet/IP or supporting both
Supports Device Level Ring (DLR) topology
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.
The VLT® EtherNet/IP MCA 121 option
oers plug and play connectivity to
EtherNet/IP based networks, such as
Rockwell PLC systems, via the Com-
mon Industry Protocol (CIP
The option can handle a single Ether-
Net/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
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
n Built-in web-server for remote
diagnosis and reading out basic drive
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
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
n EtherNet/IP (Industrial Protocol) for
controlling and parameter settings
CIP (Common Industry Protocol) For
HTTP (Hypertext Transfer Protocol)
for diagnosis via build-in web server
SMTP (Simple Mail Transfer Protocol)
DHCP (Dynamic Host Configuration
Protocol) automatic IP address
