10.13.2.2 Completing the testContinue to test another function or end the test by changing the TestMode setting toOff. Restore connections and settings to their original values, if they were changed fortesting purposes.10.14 Station communication10.14.1 Multiple command and transmit MULTICMDRCV /MULTICMDSNDThe multiple command and transmit function (MULTICMDRCV /MULTICMDSND) is only applicable for horizontal communication.Test of the multiple command function block and multiple transmit is recommendedto be performed in a system, that is, either in a complete delivery system as anacceptance test (FAT/SAT) or as parts of that system, because the command functionblocks are connected in a delivery-specific way between bays and the station level andtransmit.Command and transmit function blocks included in the operation of different built-infunctions must be tested at the same time as their corresponding functions.10.15 Remote communication10.15.1 Binary signal transfer BinSignReceive, BinSignTransmPrepare the IED for verification of settings as outlined in section "Preparing the IEDto verify settings".To perform a test of Binary signal transfer function (BinSignReceive/BinSignTransm), the hardware (LDCM) and binary input and output signals totransfer must be configured as required by the application.There are two types of internal self supervision of BinSignReceive/BinSignTransm• The I/O-circuit board is supervised as an I/O module. For example it generatesFAIL if the board is not inserted. I/O-modules not configured are not supervised.• The communication is supervised and the signal COMFAIL is generated if acommunication error is detected.Status for inputs and outputs as well as self-supervision status are available from thelocal HMI underSection 10 1MRK 511 360-UEN ATesting functionality by secondary injection188 Bay control REC670 2.1 IECCommissioning manual
