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

y 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.
y If the IP address will be set by the DCP protocol, the IP address of the sensor will be initialized.
y 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.
