Synchronization via DNPThe DNP3 communication can be the source for the coarse time synchronization,while the fine time synchronization needs a source with higher accuracy. See thecommunication protocol manual for a detailed description of the DNP3 protocol.Synchronization via IEC60870-5-103The IEC60870-5-103 communication can be the source for the coarse timesynchronization, while the fine tuning of the time synchronization needs a source withhigher accuracy. See the communication protocol manual for a detailed description ofthe IEC60870-5-103 protocol.15.2.9 Technical dataTable 497:Time synchronization, time taggingFunction ValueTime tagging resolution, events and sampled measurement values 1 msTime tagging error with synchronization once/min (minute pulsesynchronization), events and sampled measurement values± 1.0 ms typicallyTime tagging error with SNTP synchronization, sampled measurementvalues± 1.0 ms typically15.3 Parameter setting group handling15.3.1 FunctionalityUse the four different groups of settings to optimize the IED operation for differentpower system conditions. Creating and switching between fine-tuned setting sets,either from the local HMI or configurable binary inputs, results in a highly adaptableIED that can be applied to a variety of power system scenarios.15.3.2 Setting group handling SETGRPS15.3.2.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberSetting group handling SETGRPS - -1MRK 511 287-UEN A Section 15Basic IED functions557Technical manual
