A PROFINET IO controller can assign an IP address to the IOLM gateway via DCP. The IO controller and
the Emerson IOLM gateway have to be on the same subnet. The IOLM default IP address is:
192.168.11.202 and the subnet mask is 255.255.255.0.
To assign IP address/device name from the DCP tool, navigate to Utilities menu item in PAC Machine
Edition and select PROFINET DCP
