TagSamples Parameter

• Blob – Stores tags as binary large objects. The Blob datatype generally refers to undetermined binary data types, such as an Excel spreadsheet, a PDF file, or a Word file.
• Boolean (one byte) – Stores boolean values. Valid values for the boolean data type are 0=FALSE and 1=TRUE. If the user sends zero, the value is taken as zero. Anything other than zero, the value is treated as one.
• Byte (one byte) – Stores integer values. Valid values for the byte data type are -128 to +127.
• SingleFloat (four bytes) – Stores decimal values up to six places. Valid ranges for the single float data type are 1.175494351e-38F to 3.402823466e+38F
• DoubleFloat (eight bytes) – Stores decimal values up to 15 places. Valid values for the double float data type are 2.2250738585072014e-308 to 1.7976931348623158e+308.
• SingleInteger (two bytes) – Stores whole numbers, without decimal places. Valid values for the single integer data type are -32767 to +32767.
• DoubleInteger (four bytes) – Stores whole numbers, without decimal places. Valid values for the double integer data type are -2147483648 to +2147483648.
• FixedString (Configured by user) – Stores string data of a fixed size. Valid values are between 0 and 255 bytes.
• Float – Single float.
• Integer – Single integer.
• MultiField – Stores string data that has multiple words.
• QuadInteger (eight bytes) – Stores whole numbers without decimal places. Valid values for the quad integer data type are -9,223,372,036,854,775,808 (negative nine quintillion) to +9,223,372,036,854,775,807 (positive nine quintillion).
• Scaled (two bytes) – Lets you store a four-byte float as a twobyte integer in the Historian archive. The scaled data type saves disk space but sacrifices data precision as a result.
• Time – Returns or sets the type of time stamping applied to data at collection time.
• UDoubleInteger (Unsigned Double Integer) (four bytes) – Stores whole numbers without decimal places. Valid values for the unsigned double integer data type are 0 to 4,294,967, 295 (4.2 billion).
• Undefined – Data type is not defined.
• UQuadInteger (Unsigned Quad Integer) (eight bytes) – Stores whole numbers without decimal places. Valid values for the unsigned quad integer data type are 0 to 18,446,744,073,709,551,615 (19 quintillion).
• USingleInteger (Unsigned Single Integer) (two bytes) – Stores whole numbers without decimal places. Valid values for the unsigned single integer data type are 0 to 65535.
• VariableString (No fixed size) – Stores string values of undetermined size. This data type is useful if you cannot rely on a constant string length from your data source.
• Array – Returns an array of tags from your data source. You can specify orientation, size, and number of rows returned in the array.
