Configuring Ethernet connection, LOGO! to LOGO! slave

LOGO!Soft Comfort supports the connection of a LOGO! Base Module to a LOGO! slave only through network blocks.

Follow the same steps as Configuring Ethernet connection, LOGO! to remote devices.

Select the LOGO! Slave device's IP address in the dropdown list of Device/IP address in the Remote device configuration area. The Device type automatically changes to LOGO! Slave.

You can only create connections between a LOGO! Base Module and a LOGO! slave device using network function blocks (NI/NQ/NAI/NAQ). Drag-and-drop operations are not available in this case.
