Analog Quantities
Maximum/Minimum Metering
Note8: For each of the maximum or minimum analog quantities, the corresponding time stamp is also reported in Modbus. In
addition, the time when Max/Min data was last reset is also reported in Modbus (the actual labels used in the Modbus
Map are not MM_LRDH, MM_LRDM, MM_LRDL).
Note9: EU is Engineering Units.
