Remote Ethernet Interfaces
NET 1
NET 1 is an interface composed by an RJ45 communication connector pattern 10/100Base-TX. It
allows point-to-point or network communication in the following open protocols: MODBUS TCP
Client, MODBUS RTU via TCP Client, MODBUS TCP Server and MODBUS RTU via TCP Server.
The parameters which must be configured for the proper functioning of the application are described
below:

Reserved TCP Ports
The following TCP ports of the Ethernet interfaces, both local and remote, are used by CPUs
services, so they are reserved and cannot be used by the user: 80, 161, 8080, 1217, 1740, 1741,
1742,1743 and 11740.
NX5000 Module Configuration
The NX5000 modules can be inserted in the project to increase the number of Ethernet interfaces if
the local CPU interfaces are not enough. Only the NX3020 and NX3030 CPUs support the NX5000
module.
The Ethernet channels of the NX5000 modules can be used individually, or arranged in NIC Teaming
pairs. NIC Teaming pairs are used to provide redundant Ethernet channels.
An example of typical application for NX5000 module is the setting of a redundant HSDN (High
Speed Deterministic Network) for communication between different PLCs. Through this network,
several PLCs can exchange messages in an entirely segregated network to ensure determinism and
fast communication. Moreover, setting up this network as redundant with NIC Teaming pairs,
provides an excellent availability. To build a redundant HSDN, two NX5000 modules must be
inserted. Figure 4-9 shows an example of redundant HSDN using two NX5000 modules.
The Figure 4-9 also shows an example with one NX5000 module used isolated (without NIC
Teaming redundancy), inserted to the right of the other modules.
