CHAPTER 2: MODBUS COMMUNICATION FILE TRANSFERSUR FAMILY – COMMUNICATIONS GUIDE 2-1122.3.1.7 Reading fault report filesFault report data has been available via the UR file retrieval mechanism since UR firmware version 2.00. The file name isfaultReport#####.htm. The ##### refers to the fault report record number. The fault report number is a counter thatindicates how many fault reports have ever occurred. The counter rolls over at a value of 65535. The last 15 fault reportsare available for retrieval. It starts from 1 to 15, then if you have 18 reports, 3 to 18 are retrieved. A request for a non-existent fault report file yields a null file. The current value fault report counter is available in "Number of Fault Reports"Modbus register at location 3020h.For example, if 14 fault reports have occurred then the files faultReport5.htm, faultReport6.htm, up tofaultReport14.htm are available to be read. The expected use of this feature has an external master periodicallypolling the "Number of Fault Reports' register. If the value changes, then the master reads all the new files.The contents of the file is in standard HTML notation and can be viewed via any commercial browser.2.3.1.8 Reading PMU recordsFor URs that support PMU, familiarity with the PMU recording feature is required to understand the following description.For example, see the PMU Recording and later sections in the N60 instruction manual.The "PMU Recording Number of Triggers" register increments by one every time a new PMU record is triggered (captured)on any of the PMU units in the relay (depending on the software option in the order code up to six PMUs can be available ina relay). When a new trigger occurs, the associated PMU record file is assigned a file identifier based on the number of thePMU module, the incremented value of this register module 1000 and the format of the COMTRADE file, as described here.This register can be used to determine if any new data has been captured by periodically reading it to see if the value haschanged; if the number has increased then new data can be available.The file "PMU_Records_List.txt" lists the available PMU records in the relay. This file can be retrieved by TFTP. This fileincludes information about the file name for every PMU record in the relay.The PMU records can be retrieved using the EnerVista software or by TFTP. The file name has the formatPMUp_xxxxn.eeewherep is the PMU recorder instancexxxx is the COMTRADE format shown in the following tablesn is the file sequence number in integer format from 1 to 999. The file sequence number is unique among all PMUs.eee is the extension (cfg, dat, hdr, cff)For example, to retrieve file 7 from PMU 3 in binary 16 bit CFF format, retrieve the file PMU3_16B7.cff.Table 2-15: PMU records for IEEE C37.111-2013, by data formatTable 2-16: PMU records for IEEE C37.111-1999, by data formatBinary Binary32 Float32 ASCIIMultiple files PMUp_16Bn.cfgPMUp_16Bn.datPMUp_16Bn.hdrPMUp_32Bn.CFGPMUp_32Bn.DATPMUp_32Bn.HDRPMUp_32Fn.CFGPMUp_32Fn.DATPMUp_32Fn.HDRPMUp_###An.cfgPMUp_###An.datPMUp_###An.hdrSingle file PMUp_16Bn.CFF PMUP_32Bn.CFF PMUp_32Fn.CFF PMUp_###An.cffBinary ASCIIMultiple files PMUp_n.cfgPMUp_n.datPMUp_n.hdrPMUp_An.cfgPMUp_An.datPMUp_An.hdr
