EtherNet/IP MCA 121
Ethernet is the future standard for communication at the
factory oor. The VLT
®
EtherNet/IP MCA 121 option is
based on the newest technology available for industrial
use and handles even the most demanding requirements.
EtherNet/IP™ extends standard commercial Ethernet to the
Common Industrial Protocol (CIP™) – the same upper-layer
protocol and object model found in DeviceNet.
MCA 121
oers advanced features such as:
•
Built-in, high-performance switch enabling line-
topology, which eliminates the need for external
switches.
•
DLR Ring (from October 2015).
•
Advanced switch and diagnosis functions.
•
Built-in web server.
•
E-mail client for service notication.
•
Unicast and Multicast communication.

Modbus TCP MCA 122
The MCA 122 option connects to Modbus TCP-based
networks. It handles connection intervals down to 5 ms in
both directions, positioning it among the fastest
performing Modbus TCP devices in the market. For master
redundancy, it features hot swapping between 2 masters.
Other features include:
•
Built-in web-server for remote diagnosis and
reading out basic drive parameters.
•
Email notication that can be congured to send
an email message to 1 or more recipients when
certain alarms or warnings occur, or when they
are cleared.
•
Dual master PLC connection for redundancy.

BACnet/IP MCA 125
The VLT
®
BACnet/IP MCA 125 option allows quick and easy
integration of the drive into building management systems
(BMS) using the BACnet/IP protocol or by running BACnet
on Ethernet. It can read and share data points and transfer
actual and requested values to and from the systems.
The MCA 125 option has 2 Ethernet connectors, enabling
daisy-chain conguration with no need for external
switches. The embedded 3-port managed switch of the
VLT
®
BACnet/IP MCA 125 option comprises 2 external and
1 internal Ethernet port. This switch allows the use of a
line structure for the Ethernet cabling. This option makes it
possible to control multiple high-eciency permanent
magnet motors in parallel and monitor points required in
typical HVAC applications. Besides standard functionality,
the MCA 125 option features:
•
COV (change of value).
•
Read/write property multiple.
•
Alarm/warning notications
•
Ability to change BACnet object names for user-
friendliness.
•
BACnet Loop object.
•
Segmented data transfer.
•
Trending, based on time or event.
