Ethernet Connection

The NC LITE node controller supports Ethernet connections of 10/100 Mb/s (auto-negotia-
tion supported). The NC-S, NC-E, and NC-12 node controllers support Ethernet connections
of 10/100/1000 Mb/s (auto-negotiation supported). Network communication allows connect-
ing a number of different devices to a factory controller using one communications cable,
which simplifies wiring. Each device that is connected to the network has a unique network
device address. Individual devices only receive communications through the network that are
addressed to that device.
The Ethernet connection that is provided by the node controllers supports both MagneMotion
proprietary TCP/IP and EtherNet/IP
PC-based host controllers and EtherNet/IP is used by PLC-based host controllers. The node
controllers always use TCP/IP for communication between node controllers. When the host
controller is unavailable, a general-purpose computer with a communications application such
©
as PuTTY (a free SSH and telnet client for Windows) or a host simulator such as NCHost,
can be connected to the transport system network for communication with the HLC.
NOTE: While both TCP/IP and EtherNet/IP use the same hardware for communication, the
communication protocol itself is different. This difference allows both protocols to
run on the same network simultaneously without interfering with each other.
For the NC-S, NC-E, the 700-1482-00 NC-12, and the NC LITE the Ethernet cables that are
used are standard network cable (UTP-Cat5) with an RJ45 connector. This cable plugs into the
NET0 port on the NC-S, the lower Network port on the NC-E, the ETHERNET port on the
NC-12, and the LAN port on the NC LITE. See the Node Controller Hardware User Manual,
MMI-UM013, for the locations of these connections.
For the 700-1573-00 NC-12, the Ethernet cables that are used are standard network cable
(UTP-Cat5) with a 4-pin M12 Eurofast connector that plugs into the ETH port. See the Node
Controller Hardware User Manual, MMI-UM013, for the location of this connection.
NOTE: To establish a direct communications link from a PC to any node controller using
Ethernet, a standard Ethernet cable can be used (auto-MDIX is supported).
TCP/IP Communication – Host Controller to HLC
TCP/IP communication is supported for use when the host controller uses explicit messaging
(typically a PC or for some PLCs that use TCP/IP). TCP/IP communication allows the host
controller to communicate with the high-level controller (HLC) as described in the Host Con-
troller TCP/IP Communication Protocol User Manual, MMI-UM003. TCP/IP communica-
tion is also used between the node controllers and the node controller that is designated as the
HLC.
