This configuration property sets the amount by which the value obtained by a data acquisition application must change before an output network variable is updated. The data type is the same as the output network variable. For network variable types that are not zero-based (for example SNVT_temp) this value is represented as a difference in two values of the SNVT concerned. For SNVT_switch the continuous (level) part follows this convention. Thus to represent a delta value of 0.5 deg C, the SCPTsndDelta value should be set to 5. Some network monitoring and control tools may display this value as -273.5°C.
