The switching of the Local/Remote switch requires at least system operator level. Thepassword will be requested at an attempt to operate if authority levels have been definedin the IED. Otherwise the default authority level, SuperUser, can handle the controlwithout LogOn.

The connections are seen in figure 178, where the inputs on function blockLOCREM are connected to binary inputs if an external switch is used. When the localHMI is used, the inputs are not used and are set to FALSE in the configuration. The outputsfrom the LOCREM function block control the output PSTO (Permitted Source ToOperate) on Bay control (QCBAY).LOCREMCTRLPSTO1PSTO2PSTO3PSTO4PSTO5PSTO6PSTO7PSTO8PSTO9PSTO10PSTO11PSTO12HMICTR1HMICTR2HMICTR3HMICTR4HMICTR5HMICTR6HMICTR7HMICTR8HMICTR9HMICTR10HMICTR11HMICTR12QCBAYLR_ OFFLR_ LOCLR_ REMLR_ VALIDBL_ UPDBL_ CMDPSTOUPD_ BLKDCMD_ BLKDLOCREMCTRLOFFLOCCTRLREMCTRLLHMICTRLOFFLOCALREMOTEVALIDIEC 09000208_1_en. vsdLOCREMIEC09000208 V2 ENFigure 178: Configuration for the local/remote handling for a local HMI with one bayand one screen pageThe switching of the local/remote switch requires at least system operator level.
