This type defines a totalizer value.
For TotalizerVariableType there are two possible IRDIs as target of the HasDictionaryEntry reference, depending on the type of the totalized quantity. In case of mass totalization the IRDI 3:0112/2///61987#ABH327#001 shall be referenced, in case of actual volume totalization the IRDI 3:0112/2///61987#ABH328#001 shall be referenced. The related HasDictionaryEntry reference shall be defined after the concrete totalizer type is known.
PulseValue: ABA418#002 defines mass quantity assigned to one pulse.
PulseValue: ABE882#001 defines volume quantity assigned to one pulse.
PulseWidth: ABA635#002 defines factory setting of the pulse width.
