Specifying the IP address using the DCP protocol
In the PROFINET communication, you can specify the IP address of I/O devices using
the DCP protocol (Discovery and Configuration Protocol).
The DCP protocol offers two methods for setting the IP address.
(1) The IP address can be set by the I/O controller based on the device name
information of the I/O device.
(2) The IP address and device name of the I/O device can be set by the I/O supervisor
(PC, etc.).
Reference
If the IP address of the I/O device will be set by the I/O controller, the I/O
device name must match the name in the config of the I/O controller.
(1) Check the presence of an I/O device
