• Members – You use the Members list to inspect the signals con-
tained by the SNVT, if the SNVT you selected in the Type list is
structured.
• Initial Value – If you want the output SNVT to have an initial
value you type the value required in the Initial Value box. This
value is kept until the signal the SNVT represents changes.
• Unit – If the SNVT has a unit you enter that unit in the Unit box.
The unit can be used for presentation by a receiving device.
• Delta – If you want the SNVT to send its value when the signal it
represents changes, you must type the minimum change value in
the Delta box.
An example of an output SNVT
In the following example, an output SNVT is added which sends a tem-
perature value every time the outside air temperature changes by more
than 0.5 °C.
