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#001shall be referenced, in case of actual volume totalization the IRDI 3:0112/2///61987#ABH328#001shall 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.

For PulseValue there are two possible IRDIs as target of the HasDictionaryEntry reference, depending on the type of the totalized quantity. The dictionary entry for PulseValue shall be 3:0112/2///61987#ABA418#001for mass flow and 3:0112/2///61987#ABE882#001for volume flow.
