CanonicalDataType

Server's data type for item

Description

CanonicalDataType indicates the data type of the item as stored on the OPC server. The MATLAB® supported data types are as for the DataType property.

You can specify that the item's value is stored in the daitem object using a data type that differs from the canonical data type, by setting the DataType property of the item to a value different from CanonicalDataType. Translation between the CanonicalDataType and the DataType is automatic.

Refer to the DataType property reference for a listing of the COM Variant data types and their equivalent MATLAB data types.
