PI status variable properties

SampleTypeCode

The data type of the sample stream for the variable. The data type must be compatible with the data type of the variable being mapped to on the PI server.

For more information, see Configure the DataType property for fields.

Boolean, DateTime, Double, Event, Int32, Int64, Single, String

Value

The value of the last sample written to the historical stream of samples.

AVEVA™ Production Management usually reads the PI point on the PI server to derive the value; however, you can also change the value of the PiVariable item directly with the Value property, or by the execution of running code.

AVEVA Production Management writes the changed value back to the PI system immediately, and updates the PiVariable item sample after the next event notification.

PiPointName

The name of the PI point on the PI system that the PiStatusVariable item maps to.

The PiPointName property is case-insensitive, and it keeps the name of the PI point on the PI server separate from the name in the Name property.

A match of the PI point name on the PI server
