NET 2
The NET 2 interface is composed by a RJ45 communication connector pattern 10/100Base-TX. It
allows the 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:
IP address of the controller in
the Ethernet bus.
1.0.0.1 to
223.255.255.254
Sub-net mask of the
controller in the Ethernet bus.
128.0.0.0 to
255.255.255.252
Gateway address of the
controller in the Ethernet bus.
1.0.0.1 to
223.255.255.254
Table 4-22. NET 2 Configuration
ATTENTION:
It is not possible to configure the two local Ethernet interfaces in the same sub-net. This kind of
configuration is blocked in MasterTool. This way, each Ethernet interface must be configured in a
different Subnetwork.
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:
IP address of the Controller in
the Ethernet bus
1.0.0.1 to
223.255.255.254
Sub net mask of the Controller
in the Ethernet bus
128.0.0.0 to
255.255.255.252
Gateway address of the
Controller in the Ethernet bus
1.0.0.1 to
223.255.255.254
Table 4-23. Remote NET 1 Configurations
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 NX3005, 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.
