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 Conguration 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.).
(1) Check the presence of an I/O device

I/O Controller
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 cong of the I/O controller.
If the IP address will be set by the DCP protocol, the IP address of the sensor will be initialized.
The IP address set by the DCP protocol will be stored in the volatile memory. When you restart the
sensor, the sensor will start up with its IP address in “----” (unregistered) status.
