PLC from the Partner port drop‑down list (the default option is Any partner, which
must be changed to the actual connected port), and click OK.
Then click the corresponding ports of the slave to set the topology. The operations
are similar to the preceding steps. After setting all connected ports, start compiling
and download the configuration to the PLC.
After completing the preceding configuration, perform the following operations when
a slave device needs to be replaced: 1) Disconnect the device from the network. 2)
Install a new device that is not assigned with a device name before at the same
position. (For S7‑1200 or S7‑1500, if Permit overwriting of device names of all
assigned IO devices has been selected, a device that has been assigned with a name
can be used.) 3) Connect the new device to the network using the original wiring
mode. (Note that the network cable connection must be consistent with the original
connection and the connection in the topology.) 4) Power on the slave station. The
PLC will assign a device name to the newly connected device automatically.
