Type of Communication According to Connection Configuration
Original instructions
Overview
Depending on the connection configuration of the Ethernet channel of the TSX P57 6634/5634/4634, you can carry out messaging.
According to the type of protocol and access control management, multi-connection mode requires a specific configuration of the correspondence table.
NOTE: In the following, only examples of multi-connection are shown. Furthermore, emphasis is placed on communications between the coprocessor and a remote PC device containing several applications.
Configuration Rules
Several connections can be configured with the same IP address. They must be defined with the same protocol, the same access rights, and the same connection mode.
In the case of a Modbus connection, only two connections can be configured with the same IP address. Addresses associated with these connections are:
Multi-Connection in UNI-TE Protocol with Access Management
In this example, the PC contains four applications with a unique X-Way address and one single IP address:
Exchanges are carried out according to the UNI-TE protocol when the coprocessor's access control utility is enabled.
In order to implement this example, you must:
Multi-Connection in UNI-TE Protocol without Access Management
This example is the same as the previous one, except that access control is not configured.
In this case, if the application {1.1} is the only server application, the coprocessor's correspondence table only contains the following line:
Multi-Connection in Modbus Protocol with Access Management
In this example, the PC contains four applications. The server application has an imaginary X-Way address and the other client applications do not need an X-Way address:
Exchanges are carried out according to the Modbus protocol when the coprocessor's access control utility is enabled.
In order to implement this example, you must:
NOTE: If you want to prevent connection by client applications you must configure
  • X-Way address: empty
  • IP address: 139.160.65.156
  • Access: not authorized (cell unchecked)
  • Mode: multi
Multi-Connection in Modbus Protocol without Access Management
This example is the same as the previous one, except that access control is not configured.
In this case (where the application {1.103} is the only server application), the coprocessor's correspondence table only contains the following line:
