Tools -> Ethernet Connections (0BA7 only)

Use this menu command to configure the module address and make Ethernet connections for the LOGO! Base Module.

①
Module Address
You firstly configure the IP address, subnet mask and gateway of the LOGO! 0BA7 Base Module before making the Ethernet connections. The default value of a Base Module is as follows:
IP address: 169.254.45.2
Subnet mask: 255.255.0.0
Gateway: 169.254.45.1
②
Ethernet connections
To add a connection, right-click "Ethernet Connections". A LOGO! 0BA7 Base Module can support a maximum of eight network connections, which are TCP/IP-based S7 communication connections to the following devices:
Additional LOGO! 0BA7 devices
SIMATIC S7 PLCs with Ethernet functionality
A maximum of one SIMATIC HMI (Operator Panel) that supports Ethernet communication with networked S7 PLCs
NOTE:
During the configuration of an S7 communication to the SIMATIC HMI, you must select S7-200 as the connection device.

Note

You can only construct a LOGO! 0BA7 network topology using LOGO!Soft Comfort V7.0.

For detailed information about S7 communication configurations between the LOGO! 0BA7, SIMATIC PLCs and HMIs, see FAQs under the Support selection at LOGO! Website.

Each S7 connection can be configured to be a Client or a Server type, in which the local IP/local TSAP (Transmission Layer Service Access Point) and remote IP/remote TSAP are configured respectively. The Server is the data source for the information that is required by the communication partner Client.

To configure the Client or Server information of each LOGO! 0BA7 connection, double-click the connection.

LOGO! 0BA7 Base Module as Client

If the LOGO! 0BA7 Base Module is configured to be a Client, it can request data transfer from remote PLCs.

①
Local Properties (Client)
TSAP is the Transmission Layer Service Access Point in TCP/IP communication.
The local TSAP of Client is automatically generated by LOGO!Soft Comfort.
②
Remote Properties (Server)
The remote TSAP is the TSAP of the Server that you want to connect.
The remote IP address is the IP address of the Server that you want to connect.
③
Data Transfer (Read: Local <- Remote, Write: Local -> Remote)
A maximum of 32 data transfers can be created in a Client connection. To insert a new data transfer row, right-click an existing row or press the Enter key on the last cell on an existing row. In the read process, data is read from the remote server and stored in the local Base Module; in the write process, data is written from the local Base Module to the remote server. You can store data where you want on the local Base Module and remote server by specifying values of the Address (Local) and Address (Remote) columns. The maximum transfer data length is 212 bytes for every data transfer.
④
Keep Alive
If you select the check box, the LOGO! 0BA7 Base Module checks the connection every five seconds.

In LOGO! Base Module, MB, IB and QB are read-only.

LOGO! 0BA7 Base Module as Server

If the Server in this connection is a SIMATIC S7 or SIMATIC HMI, you must configure the Server connection.

If the Server of this LOGO! 0BA7 Base Module is also a LOGO! Base Module, configure the Server connection from the Connection dialog by double-clicking Connection1 in the "Configure address and connections" dialog as shown above.

①
Local Properties (Server)
TSAP: The range in LOGO! 0BA7 is 20.00 to FF.FF.
The local TSAP of Server is automatically generated by LOGO!Soft Comfort. If the Operator Panel (SIMATIC HMI) is the Client in this connection, select the "Connect with an Operator Panel (OP)" check box. LOGO!Soft Comfort then automatically changes the TSAP to 02.00.
If you select the "Accept all connections requests" check box, the Server responds to the requests from all Clients in the network.
The Server can accept a request only from one IP address. This address is the IP address of the Client that you want to connect.
②
Remote Properties (Client)
The remote TSAP is the TSAP of the Client that you want to connect.
③
Keep Alive
If you select the check box, the LOGO! 0BA7 Base Module checks the connection every five seconds.

①	Local Properties (Client) TSAP is the Transmission Layer Service Access Point in TCP/IP communication. The local TSAP of Client is automatically generated by LOGO!Soft Comfort.
②	Remote Properties (Server) The remote TSAP is the TSAP of the Server that you want to connect. The remote IP address is the IP address of the Server that you want to connect.
③	Data Transfer (Read: Local <- Remote, Write: Local -> Remote) A maximum of 32 data transfers can be created in a Client connection. To insert a new data transfer row, right-click an existing row or press the Enter key on the last cell on an existing row. In the read process, data is read from the remote server and stored in the local Base Module; in the write process, data is written from the local Base Module to the remote server. You can store data where you want on the local Base Module and remote server by specifying values of the Address (Local) and Address (Remote) columns. The maximum transfer data length is 212 bytes for every data transfer.
