EM720 Power Quality and Revenue Meter 217
Appendix H OBIS Identification Codes
The OBIS (Object Identification System IEC 62056-61) codes
are used to identify energy and maximum demand readings
in the IEC 62056-21 protocol (see the EM720 IEC 62056-21
Reference Guide) and in the billing data displays on the
EM720 front display.
The OBIS code structure used in the EM720 is as follows:
B : C.D.E * F
where
B – energy metering channel 1-6. Not indicated for a single
self-metering channel when no external channels are defined.
C – identifies a physical instrumentation quantity, like the
type of a source power and its direction. 0 identifes general
purpose objects.
D – identifies a quantity processing algorithm, like time
accumulation, maximum and cumulative maximum.
E – tariff rate 1...8, or 0 for total readings.
F – billing period 0-99, 0 (or not shown) for present billing
period, 1 for the first previous (last) period, 2 for the second
previous billing period, and so on.
The following table lists the OBIS codes used in the EM720
billing data displays.
