PA-DIM TotalizerVariable

This type defines a totalizer value.

For TotalizerVariableType there are more than one 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. The default value is 1 pulse per 0.1 kg. The unit is fixed to kg.

PulseValue: ABE882#002 defines volume quantity assigned to one pulse. The default value is 1 pulse per 0.1 l. The unit is fixed to l.

PulseWidth: ABA635#003 defines setting of the pulse width. The unit is fixed to ms.

The components of TotalizerVariableType have additional references which are defined in Table 253.

For PulseValue there are more than one 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#002 for mass flow and 3:0112/2///61987#ABE882#002 for volume flow.
