Custom Properties

Sepasoft MES Module Suite

Custom Properties

Custom properties can be added to any MES object using the MES Object Editor component or with script functions. Custom properties can be nested, meaning a custom property can be added to a custom property. This allows defining a structure to custom properties such as Width, Height and Depth custom properties can be added beneath a Dimension custom property. Custom properties have a production visible option that will show the property in the MES Property Value Editor component. This provides a method to keep custom properties hidden and not show them to operators or other end users. If the custom property is visible to the end users, the required option will make sure a value is entered before ending an operation.

Warning

Custom properties belong to AbstractMESObject which is the base object for every Track & Trace and OEE Downtime object. See the custom property section of the AbstractMESObject reference for a listing of the custom property functions.

Adding Custom Properties using the MES Object Editor

The MES Object Editor has built-in support to add custom properties to any of the MES object types that can be configured using the MES Object Editor. These objects include Equipment Objects, Material Class & Material Definition, Personnel Class & Personnel, Process Segment, Operations Definition, Operations Segment.

MES object types that custom properties cannot be added to using the MES Object Editor include Material Lot, Material Sublot, MES Work Order, Request Segment, Operations Response and Response Segment, because they are only created during production. However custom properties can be added to these objects using scripting.

Custom Property Inheritance Between MES Objects

Many MES objects have parent-child relationships which allows for custom properties to be inherited. As an example, Material Definitions, will inherit any custom properties defined for the parent Material Class that they belong to. Any custom properties added and configured locally on the Material Definition that have the same name as the inherited custom property, will replace it only on the instance of the child object. Furthermore, the properties are accessible separately through the MESObject's getInheritedProperties and getCustomProperties methods and are viewable from different locations within the MES Object Editor Component.

In the image on the right, the Material Class TestClass1 has a custom property called ClassLevelCP.

When the TestMat1 Material Definition is selected, the locally configured Custom Property TestCP1 is shown. Note that the inherited custom property ClassLevelCP from the parent Material Class does not appear in the Information Panel, nor will it be returned by the obj.getCustomProperties() method. The obj.getCustomProperties() method will return TestCP1 for the TestMat1 Material Definition.

When examining the settings for the Material Definition in the example, note that the locally configured Custom Property and the Inherited Custom Property from the Material Class parent are both shown in the main information panel. To retrieve the inherited value, the obj.getInheritedProperties() method should be used, returning ClassLevelCP. Note that the inherited value is not unique to the Material Definition but is a property of the Material Class. The inherited value can be over-ridden at the child level by adding a custom property on the child with the same name as the property of the parent.

Scripting Function for Manipulating Custom Properties

Read custom property from MES Object

Copy Code
Python
#Read custom property from MES object.
 
#Load the material class object named Vinegar.
mesObject = system.mes.loadMESObject("Vinegar", "MaterialClass")
 
#Print value of custom property pH
print mesObject.getPropertyValue('pH')

addCustomProperty(name, dataTypeName, description, units, productionVisible, required, value)

Description

You can add properties to any MES object and resource complex properties, such as material, equipment, personnel, etc.

Use the methods below to add custom properties. Add a custom property directly to a MES object by not specifying a path to the parent property. To add a custom property as a child of an existing custom property or to a complex property, the parent path is used to specify the parent.

Each level of the path is separated with a period. This allows for names to be duplicated provided the path is unique. For example, it is possible for a MES object to have custom properties "Dimension 1.Width" and "Dimension 2.Width"

Syntax

addCustomProperty(name, dataTypeName, description, units, productionVisible, required, value)

  • Parameters

String name - The name of the custom property to add.

String dataTypeName - The name of the Ignition data type to make the new custom property.

String description - The description of the custom property.

String units - The units of the new custom property. This is just for reference.

Boolean productionVisible - The default is false. If True, show the custom property in various components. If False, it will be hidden and can be used to store values behind the scenes.

Boolean required - If True, a value must be assigned to the custom property before and segment is ended.

String value - The value to assign to the custom property after it has been added.

  • Returns

Nothing

getBaseName()

Complex properties that use extended naming have an associated base name and a number following it. This is used with Lot Reference Property that the Response Segment uses. Each time a lot reference is created it is named the base name with an extension added to it.

For example:

If balsamic vinegar is being unloaded and the tank it is being stored in fills up before the truck is fully unloaded. When it is switched to another storage tank a new lot reference is created. If the name of the material reference in the Process Segment is named Vinegar, then the first lot reference is named Vinegar-1 for the first storage tank and the second is Vinegar-2 for the second storage tank.

Description

Get the base name for the complex property.
