- PROFINET Communication Unit DL-PN1 User's Manual (IB) -

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.
