If you create a metadata field for this property, then an error will occur if you set the field to an invalid value for this property. HCAL will not export data for that point or accumulator.
In Geo SCADA Expert, only Float, Double, Int2 and Int4 are used. Geo SCADA Expert uses Int2 for all digital type points. This is because Geo SCADA Expert supports 1-, 2- and 3-bit digital points. Int1 can only be used for discrete tags with just two states.
