Data transfer table

See Tools -> Ethernet Connections (LOGO! 8.FS4 and later versions only) for more information about data transfer configurations.

Note

When your device supports both S7 and Modbus connection, Siemens recommends you connect your device to LOGO! with S7 connection.

Note

If you connect the dynamic connector with an Modbus compatible device, LOGO!Soft Comfort disables the server/client check boxes. The LOGO! Base Module with the dynamic connector is always the server in this connection.
