A common write from PCM600 to the IED, where parameters arechanged in PST, will overwrite any parameter changes made locallyfrom LHMI.It is possible to export parameters from PST in XRIO format.All variables listed and shown in the parameter list can be sorted into two groups:• Configuration parameter or• Setting parameterConfiguration parameterA configuration parameter specifies an operation mode of an application functionor of the IED. These are basic configurations, which are normally configured onlyonce and then settled. The IED configures itself at start-up according to the givenconfiguration parameter values.Setting parameterA setting parameter (short form only “setting”) is a parameter that can be changedin the IED at runtime.Setting groupNearly all settings used by the IED for the protection application functions areorganized in a group of settings. Up to six setting groups can be configured withdifferent values. The IED supports the selection of a setting group at runtime.IED parameters organizationThe organization of the parameters in a tree structure is visible in the plantstructure by expanding the setting tree.5.3 Connecting signals in SMTSMT is used to do cross references, see Figure 36:• between physical IO signals and function blocks.• for the GOOSE engineering.Section 5 1MRK511240-UEN BProtection and control engineering52 670 seriesEngineering Manual
