Connection Configuration Parameters

Introduction

This field is used to:

configure the number of connections that can be opened by the module
activate an access control service
list the remote devices that can connect to the module according to a communication protocol

Connections Which Can be Opened

The Connections which can be opened field gives the maximum number of remote devices that can be connected to the module in parallel:

The default value is 8 connections.
The value is between 1 and 32 connections.

NOTE: You are recommended to set this parameter to a useful value in order to optimize the communication resources for each connection point.

Access Control

The Access control box is used to activate (or not) control of the remote devices trying to open a TCP connection to the module:

If the box is checked, access control management is activated and the Access column of the table is active (no longer grayed out).

Where the module operates in server mode, only remote devices selected by the Access box of the table are authorized to connect as clients before communicating.
If the box is unchecked, access control management is inoperative and the Access column of the table is not active (grayed out).

Where the module operates in server mode, remote third-party devices can connect as clients (before communicating with the module) without having to be declared in the table.

NOTE: Access control is only effective on the TCP/IP profile and assists module operations in server mode.

Correspondence Table

This table is used to:

list the remote devices for which the local modules wish to open a TCP connection and for transmission (with the module operating in client mode)
provide correspondence between the X-Way address {network, station} and the IP address
- The network number must be less than or equal to 127.
- The station number is between 0 and 63 for a UNI-TE connection or between 100 and 163 for a Modbus connection.
specify the communication protocol during connection (using a drop-down menu) for each remote device of type TSX ETY 110 or TSX ETY 210
- UNI-TE (default value)
- Modbus
in the case of access control management, to designate the remote devices authorized to open a TCP connection and then to transmit to the local module (the module operating in server mode)
for each remote IP address, to choose the connection mode using a drop-down menu:
- Mono-connection: The module allows only one connection with the same remote IP address.
- Multi-connection: The module allows only one connection in client mode with the same remote IP address and several connections in server mode with the same remote IP address.

X-Way Profile

This field is specific to the TSX P57 6634/5634/4634 and allows you to choose whether or not to use an X-Way profile.

Check the box and complete the X-Way network/station address. If the X-Way profile has not been checked, the station cannot participate in X-Way exchanges. It may however be connected to Control Expert or to Modbus applications.
