PROFINET Communication
‑96‑
If information similar to that shown in the following figure is displayed, the device
name is assigned successfully. The displayed PROFINET device name must be
consistent with that displayed in the preceding figure. After assigning the device
name, close the window or select another device from the PROFINET device name
drop‑down list to assign device names for other stations.
The slave will save the assigned name, and the master identifies each slave based
on the device name. (The MAC address is not intuitive in use. The process of
assigning the device name is actually binding the device name with the MAC
address.)
● Each device name can be assigned to only one slave in the network.
● After modifying the device name of a station in the configuration, device name
assignment must be performed again. (For any exception, see "Troubleshooting".)
● After modifying the IP address, you only need to download the modified
configuration to the PLC to validate it. Name assignment is not required.
After the preceding steps, the PROFINET slave is configured. Now, you can compile
programs in the PLC to control the AC drive. Reading and writing to slaves on the PLC
are similar to those of PROFIBUS DP.
