Refer to the following table for the key configurable properties of Stored variable.

Data properties

Data	Description	Valid values
SampleTypeCode	(Required) The data type of the value of the variable. Default: Single	Boolean, DateTime, Double, Event, Int32, Int64, Single, String.
UpdateMode	The setting that initializes the data stream. Use the default Auto mode when the stored variable stores data, for example, a setpoint, that changes only when a user enters a new value. Use the OnWrite mode in cases where, for example, you have a code item that continually obtains values and enters the data into the stored variable stream, for example, custom connector or signal generator. Default: Auto	Auto, OnWrite
Value	The latest value of the StoredVariable item. You can use this item to directly change the value of the item. AVEVA™ Production Management usually reads the variable tag to derive the value. Default: No value
