The connector is intendedfor configuration and setting purposes.Rear communication via the X1/LAN1 connector uses a communication modulewith the optical LC Ethernet connection.The HMI connector X0 is used for connecting an external HMI to the IED. The X0/HMI connector must not be used for any other purpose.17.4.1 Ethernet RJ-45 front connectionThe IED's LHMI is provided with an RJ-45 connector designed for point-to-pointuse. The connector is intended for configuration and setting purposes. The interfaceon the PC has to be configured in a way that it obtains the IP address automaticallyif the DHCPServer is enabled in LHMI. There is a DHCP server inside IED for thefront interface only.The events and setting values and all input data such as memorized values anddisturbance records can be read via the front communication port.Only one of the possible clients can be used for parametrization at a time.• PCM600• LHMIThe default IP address of the IED through this port is 10.1.150.3.The front port supports TCP/IP protocol. A standard Ethernet CAT 5 crossovercable is used with the front port.17.4.2 Station communication rear connectionThe default IP address of the IED through the Ethernet connection is 192.168.1.10.The physical connector is X1/LAN1. The interface speed is 100 Mbps for the100BASE-FX LC alternative.Section 17 1MRK 502 034-UEN -IED physical connections530Technical Manual
