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-
connected. If a fifth connection to the status TCP/IP port is attempted, it causes the first status
connection to be disconnected.
The TCP/IP connection to all node controllers uses standard Ethernet network wiring. If mul-
tiple node controllers are connected to the same network, the IP address of each additional
node controller must be changed to a unique address to avoid IP conflicts. The TCP/IP address
that is used on the node controllers must be configured as specified in the
Node Controller
Interface User Manual , MMI-UM001 .
TCP/IP Communication – Node Controller to Motor Drive
When using QSHT 5700 inverters, the NC-S, NC-E, NC-12, and NC LITE node controllers
are connected to the drives for the motors in a network using standard Cat 5 cable. The motors
can use different network style connection schemes depending on the application (see
Ether-
net Motor Communication Recommendations on page 79 ).
When using Ethernet, the motor drives for all motors in a specific path must be connected to
the same node controller (see
Figure 3-15 on page 81 through Figure 3-26 on page 87 ). Addi-
tionally, multiple paths can be connected to the node controller using the same Ethernet chain.
See
Figure 4-20 for the location of these connections on the QSHT 5700 inverter. See the
Node Controller Hardware User Manual , MMI-UM013 , for the locations of these connec-
tions on the node controllers.
TCP/IP Communication – Motor Drive to Motor Drive
When using QSHT 5700 inverters, which support Ethernet communication, the motor drives
are connected to each other or the network, depending on the connection scheme being used
(see
Ethernet Motor Connection Examples on page 80 ), using standard Cat 5 cable. If multiple
motor drives are connected to the same network, the IP address of each drive must be unique
to avoid IP conflicts. The TCP/IP address that is used on the motor drives must be configured
as specified in
Ethernet Motor Communication Recommendations on page 79 .
EtherNet/IP Communication – Host Controller to HLC
EtherNet/IP communication is supported for use when the host controller uses UDP-based
implicit messaging (typically a PLC). EtherNet/IP communication allows the host controller
to communicate with the HLC as described in the
Host Controller EtherNet/IP Communica-
tion Protocol User Manual , MMI-UM004 .
The connection from the host controller to the node controller that is configured as the HLC
uses standard Ethernet network wiring. The EtherNet/IP address that is used on the node con-
troller that is configured as the HLC must be configured as specified in the
Node Controller
Interface User Manual , MMI-UM001 .
