17.12.3 Setting guidelinesThe settings tAlarm and tWarning are user settable limits defined in seconds. Theachievable resolution of the settings depends on the level of the values defined.A resolution of 10 ms can be achieved when the settings are defined within the range1.00 second ≤ tAlarm ≤ 99 999.99 seconds1.00 second ≤ tWarning ≤ 99 999.99 seconds.If the values are above this range, the resolution becomes lower due to the 32 bit floatrepresentation99 999.99 seconds < tAlarm ≤ 999 999.0 seconds99 999.99 seconds < tWarning ≤ 999 999.0 secondsNote that tAlarm and tWarning are independent settings, that is, there is nocheck if tAlarm > tWarning.The limit for the overflow supervision is fixed at 999999.9 seconds.17.13 Comparator for integer inputs - INTCOMP17.13.1 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberComparison of integer values INTCOMP Int<=>17.13.2 ApplicationThe function gives the possibility to monitor the level of integer values in the systemrelative to each other or to a fixed value. It is a basic arithmetic function that can be usedfor monitoring, supervision, interlocking and other logics.17.13.3 Setting guidelinesFor proper operation of comparison the set value should be set within the range of ± 2×109.Section 17 1MRK 506 369-UUS -Logic810 Line distance protection REL670 2.2 ANSIApplication manual
