Overview:Temp difference.
(degrees Celsius.)
.
Used to communicate temperature differences. e.g., a unit has two temperature probes A and B. The value to be reported is A – B. This type would be used allow another device to format the data from a network variable using this SNVT correctly when converting from ºC to ºF, if needed. This conversion requires a 32ºF offset converting to or from Fahrenheit temperature values, but no offset when converting to or from differential Fahrenheit temperature values. If there was no differential temperature SNVT, then the conversion can only be accomplished by the front-end system, or HMI, knowing the particular network variable.
