If the green Ready LED continues to flash after the startup, the IED has detected aninternal error. Navigate via Main menu/Monitoring/IED status to investigate theerror description.2.5 Setting up communication between PCM600 and theIEDThe communication between the IED and PCM600 is independent of the usedcommunication protocol within the substation or to the NCC.The communication media is always Ethernet and the used protocol is TCP/IP.Each IED has an Ethernet interface connector on the front and on the rear side. BothEthernet connectors can be used for communication with PCM600.When an Ethernet-based station protocol is used, PCM600 communication can usethe same Ethernet port and IP address.For the connection of PCM600 to the IED, two basic variants have to be considered.• Direct point-to-point link between PCM600 and the IED front port.• Indirect link via a station LAN or from remote via a network.The physical connection and the IP address must be configured in both cases to enablecommunication.The communication procedures are the same in both cases.1. If needed, set the IP address for the IEDs.2. Set up the PC or workstation for a direct link (point-to-point), or3. Connect the PC or workstation to the LAN/WAN network.4. Configure the IED IP addresses in the PCM600 project for each IED to match theIP addresses of the physical IEDs.Setting up IP addressesThe IP address and the corresponding mask can be set via the LHMI for each availableEthernet interface in the IED. Each Ethernet interface has a default factory IP addresswhen the complete IED is delivered.• The default IP address for the IED front port is 192.168.0.254 and thecorresponding subnetwork mask is 255.255.255.0, which can be set via the localHMI path Main menu/Configuration/Communication/TCP-IPconfiguration/Front port.• The default IP address for the IED rear port is 192.168.2.10 and the correspondingsubnetwork mask is 255.255.255.0, which can be set via the local HMI path Mainmenu/Configuration/Communication/TCP-IP configuration/LAN1.1MRS756801 E Section 2Starting up630 series 13Commissioning Manual
