Position is received through theIPOS1 and IPOS2 inputs and distributed in the configuration through the POS1and POS2 outputs, or to IEC 61850 through reporting, or GOOSE.• for commands that are received via the local HMI or IEC 61850 and distributedin the configuration through outputs CMDPOS12 and CMDPOS21.The output CMDPOS12 is set when the function receives a CLOSE commandfrom the local HMI when the SLD is displayed and the object is chosen.The output CMDPOS21 is set when the function receives an OPEN commandfrom the local HMI when the SLD is displayed and the object is chosen.It is important for indication in the SLD that the a symbol is associatedwith a controllable object, otherwise the symbol won't be displayed onthe screen. A symbol is created and configured in GDE tool inPCM600.The PSTO input is connected to the Local remote switch to have a selection ofoperators place, operation from local HMI (Local) or through IEC 61850 (Remote).An INTONE connection from Fixed signal function block (FXDSIGN) will allowoperation from local HMI.As it can be seen, both indications and commands are done in double-bitrepresentation, where a combination of signals on both inputs/outputs generate thedesired result.The following table shows the relationship between IPOS1/IPOS2 inputs and thename of the string that is shown on the SLD. The value of the strings are set in PST.1MRK502052-UEN B Section 14Control767Technical manual
