Provides information to classify a value using codes for units of measurements.

## Syntax

<div class="api-signature" data-lang="csharp">

```csharp
public class OpcEngineeringUnitInfo
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
<OpcDataType(887)>
Public Class OpcEngineeringUnitInfo
```

</div>

## Inheritance

[Object](https://learn.microsoft.com/dotnet/api/system.object) → **OpcEngineeringUnitInfo**

## Remarks

The codes used should match the codes for units of measurements defined by the United Nations Centre for Trade Faciliation and Electronic Business (see UN/CEFACT: UNECE Recommendation N° 20). It uses and is based on the International System of Units (SI Units) but in addition provides a fixed code that can be used for automated evaluation. This recommendation has been accepted by many industries on a global basis.

An instance travels as the structure EUInformation (OPC 10000-8), also as the value of a variable or an argument of a method whose data type is the abstract Structure.
