Figure 8: Point-to-point link between IED and PCM600 using a null-modem
cable
The following description is an example valid for standard PCs using Microsoft
Windows operating system. The example is taken from a Laptop with one Ethernet
interface.
Administrator rights are required to change the PC communication
setup. Some PCs have the feature to automatically detect that Tx
signals from the IED are received on the Tx pin on the PC. Thus, a
straight (standard) Ethernet cable can be used.
When a PC is connected to the IED and the setting DHCPServer is set to On via
the local HMI path Main menu/Configuration/Communication/TCP-IP
configuration/1:ETHFRNT/DHCPServer, the IEDs DHCP server for the front
port assigns an IP address for the PC. The PC must be configured to obtain its IP
address automatically as described in the following procedure.
