The ISA95MaterialDataType is a subtype of OPC UA Structure that defines a material resource, and an optional description, material use, quantity and unit of measure, description, and collection of properties.

The structure is defined in Table 27.

Table 27 – ISA95MaterialDataType Structure

Name Type Description
ISA95MaterialDataType structure  
   MaterialClassID 0:String Optional: An identification of a Material Class, or null if the Material Class is not used to identify the material.
Note: Either a MaterialClassID, MaterialDefinitionID, MaterialLotID, or MaterialSublotID must be defined.
   MaterialDefinitionID 0:String Optional: An identification of a Material Definition, or null if the Material Definition is not used to identify the material.
   MaterialLotID 0:String Optional: An identification of a Material Lot, or null if the Material Lot is not used to identify the material.
   MaterialSublotID 0:String Optional: An identification of a Material Sublot, or null if the Material Sublot is not used to identify the material.
   Description 0:String Optional: Additional information and description about the material.
            MaterialUse 0:String Optional: Information about the expected use of the material.
Defines values from ANSI/ISA 95 Part 2 are:
* consumable: resources that are not normally included in bills of material or are not individually accounted for in specific operations requests or are not lot tracked.
* material consumed: raw and intermediate material normally included in bills of material or are individually accounted for in specific operations requests or are material lots tracked.
* material produced: finished goods material normally included in bills of material or are individually accounted for in specific operations requests or are material lots tracked.
* co-product produced: a planned product typically produced in conjunction with a main planned product per the material master. A product that is usually manufactured together or sequentially because of product or process similarities.
* by-product produced: tracked waste, undesirable materials, material of value produced as a residual of or incidental to the production process. The ratio of by-product to primary product is usually predictable. By-products may be recycled, sold as-is, or used for other purposes
   Quantity 0:DecimalString Optional: The quantity of the material.
            UoM 0:String Optional: The Unit of Measure of the quantity.
Units of Measure.
   Properties ISA95PropertyDataType[] Optional: Any associated properties of the material, or empty if there are no material properties defined.
