Communication
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 with one communication cable, which
simplifies wiring. Each device that is connected to the network has a unique network device
address. Individual devices only receive communication through the network that is addressed
to that device.
The Ethernet connection that is provided by the node controllers supports both MagneMotion
proprietary TCP/IP and EtherNet/IP
™
communication protocols. The node controllers always
use TCP/IP for communication between node controllers. When the host controller is unavail-
able, a general-purpose computer with 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 communication link from a host controller to any node control-
ler 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.
TCP/IP communication allows the host controller to communicate with the high-level control-
ler (HLC) as described in the Host Controller TCP/IP Communication Protocol User Manual,
MMI-UM003. TCP/IP communication is also used between the node controllers and the node
controller that is designated as the HLC.
There is one Host control connection and four Host status connections on the HLC. If a sec-
ond Host attempts to connect to the Host control TCP/IP port, it causes the first Host to be dis-
