Network Configuration Principle Using Unity Pro
At a Glance
With Unity Pro, the installation of a network takes place from the application browser and from the hardware configuration editor.
The method involves the following four steps:
creation of a logic network, configuration of the logic network, declaration of the module or of the PCMCIA card (for Premium), association of the card or of the module with the logic network.
These four methods are presented further on in this documentation.
NOTE: The advantage of this method is that from the second step onwards, you can design your communication application (you do not need the hardware to start working) and use the simulator for functional testing of it.
NOTE: The first two steps are carried out in the project browser and the following two in the hardware configuration editor.
This manual introduces the method. For details of the various network configurations, please refer to the following documentation:
Ethernet configuration for Premium (see Premium and Atrium Using Unity Pro, Ethernet
Network Modules, User Manual) and Ethernet configuration for Modicon M340 (see Modicon
M340 for Ethernet, Communications Modules and Processors, User Manual),
Modbus Plus configuration (see Premium and Atrium Using Unity Pro, Modbus Plus Network,
User Manual),
Fipway configuration (see Premium and Atrium using Unity Pro, Fipway Network, User Manual).

At a Glance
In an intermediate station, the management of several network couplers requires a configuration phase in order to distribute the functional characteristics to the various network entities.
126
NOTE: Multi-network routing information is constructed at the station level at the time of configuration of each bridge. No consistency check is done on routing data for the same network architecture.

Configuration of X-Way Routing
Configuration of Multi-Network Services
At a Glance
In a station that supports various network modules, each network connection point is considered as an address for the station. When configuring each module, it is necessary to define the list of network numbers that are accessible for each connection point.
Depending on the processor selected during hardware configuration, a bridge station can only manage 3 or 4 network modules. The table will therefore have a maximum of 4 elements.
Illustration
A specific screen allows entry of routing data for all the network modules of a station.

Messaging
To use the communication function (see Unity Pro, Communication, Block Library) such as
Read_VAR for ethernet exchange between stations, configure the TCP/IP Messaging in the
Ethernet network configuration (see Premium and Atrium Using Unity Pro, Ethernet Network
Modules, User Manual) screen. In the Messaging tab, for each exchange set the IP address and target XWay address.
For example if station R3 needs to communicate with station B, in R1Messaging tab:
set the R2 IP address (139.255.255.4) in the field IP address, and set the B XWay address (11.4) in the field XWay address.
The following illustration shows the R1 Messaging tab:
For another example if station B needs to communicate with station A, in R2, Messaging tab: set the R1 IP address (139.255.255.5) in the field IP address, and set the A XWay address (21.7) in the field XWay address.

Mode
The first parameter to select is the Mode. With it you can select one of the following communication modes: local (communication by bus) remote (communication by network)
Network Level
For remote communications only, the network level is used to:
enter the network number, enter the station number, select the station type.
Station Level
Depending on the communication function, with this parameter the type of exchange can be selected:
The Application box selects an exchange with a PL7 application (corresponds to APP addressing).
The System box selects the PLC system of the station designated by the network level
(corresponds to SYS addressing).
The Module box means that the destination device is connected to the station via a link (Uni-
Telway, Modbus, Modbus Plus or Fipio). This case requires you to specify:
the position of the module supporting this link,
the type of this module.
Protocol
The Protocol field defines the exchange protocol used between the station on the network and the exchange’s destination device.
Device Level
This parameter is used to specify:
the type of destination device, the address of this device.

Limitations
In the address entry help screen, communications from a Uni-Telway slave require coding of the destination address in the transmission buffer (see Unity Pro, Communication, Block Library).
The help window allows full entry of the section corresponding to ADDR() advising the user that the additional buffer must be coded.
Remote station address coding is only supported by the following devices: TSX 17, TSX 37,
TSX 47-107, TSX 57.
For third-party devices, only entry of the port number is proposed. In other cases the address must be entered manually.
