• Backup – By selecting the Backup check box, the momentary
value of the SNVT is stored in the memory of the Xenta 913. If the
Xenta 913 is restarted, the stored value is used until a new value is
propagated on the network or until the Xenta_913 polls the value.
• 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 input SNVT to have an initial value
before value is received over the network you type the value
required in the Initial Value box.
• Unit – If the SNVT has a unit you enter that unit in the Unit box.
The unit can be used for presentation by the Xenta 913.
• Delta – The Delta box is used only when you add an output
SNVT.
