GE Multilin N60 Network Stability and Synchrophasor Measurement System C-13APPENDIX C C.5 IEC 61850 IMPLEMENTATION VIA ENERVISTA UR SETUPC• MMXU deadbands, which includes deadbands for all available MMXUs. The number of MMXUs is related to the num-ber of CT/VT modules in the relay. There are two MMXUs for each CT/VT module. For example, if a relay contains twoCT/VT modules, there will be four MMXUs available (access through the Settings > Product Setup > Communica-tions > IEC 61850 > MMXU Deadbands menu tree in EnerVista UR Setup).• GGIO1 status configuration, which includes the number of status points in GGIO1 as well as the potential internal map-pings for each GGIO1 indication. However only the number of status points will be used in the ICD creation process(access through the Settings > Product Setup > Communications > IEC 61850 > GGIO1 Status Configurationmenu tree in EnerVista UR Setup).• GGIO2 control configuration, which includes ctlModels for all SPCSOs within GGIO2 (access through the Settings >Product Setup > Communications > IEC 61850 > GGIO2 Control Configuration menu tree in EnerVista URSetup).• Configurable transmission GOOSE, which includes eight configurable datasets that can be used for GOOSE transmis-sion. The GOOSE ID can be specified for each dataset (it must be unique within the IED as well as across the wholesubstation), as well as the destination MAC address, VLAN priority, VLAN ID, ETYPE APPID, and the dataset items.The selection of the dataset item is restricted by firmware version; for version 5.5x, only GGIO1.ST.Indx.stVal andGGIO1.ST.Indx.q are valid selection (where x is between 1 to N, and N is determined by number of GGIO1 statuspoints). Although configurable transmission GOOSE can also be created and altered by some third-party system con-figurators, we recommend configuring transmission GOOSE for GE Multilin IEDs before creating the ICD, and strictlywithin EnerVista UR Setup software or the front panel display (access through the Settings > Product Setup > Com-munications > IEC 61850 > GSSE/GOOSE Configuration > Transmission > Tx Configurable GOOSE menu treein EnerVista UR Setup).• Configurable reception GOOSE, which includes eight configurable datasets that can be used for GOOSE reception.However, unlike datasets for transmission, datasets for reception only contains dataset items, and they are usually cre-ated automatically by process of importing the SCD file (access through the Settings > Product Setup > Communi-cations > IEC 61850 > GSSE/GOOSE Configuration > Reception > Rx Configurable GOOSE menu tree inEnerVista UR Setup).• Remote devices configuration, which includes remote device ID (GOOSE ID or GoID of the incoming transmissionGOOSE dataset), ETYPE APPID (of the GSE communication block for the incoming transmission GOOSE), andDATASET (which is the name of the associated reception GOOSE dataset). These settings are usually done automat-ically by process of importing SCD file (access through the Settings > Inputs/Outputs > Remote Devices menu treein EnerVista UR Setup).• Remote inputs configuration, which includes device (remote device ID) and item (which dataset item in the associatedreception GOOSE dataset to map) values. Only the items with cross-communication link created in SCD file should bemapped. These configurations are usually done automatically by process of importing SCD file (access through theSettings > Inputs/Outputs > Remote Inputs menu tree in EnerVista UR Setup).C.5.3 ABOUT ICD FILESThe SCL language is based on XML, and its syntax definition is described as a W3C XML Schema. ICD is one type of SCLfile (which also includes SSD, CID and SCD files). The ICD file describes the capabilities of an IED and consists of fourmajor sections:• Header• Communication• IEDs• DataTypeTemplates
