MES Platform 2.0
MES Platform 1.0
MES 3.0
For manufacturing tasks involving materials, the system represents material resources with material objects. The material may be raw material that goes into finished goods, or it may be a consumable or by-product that is not directly related to the finished good.
Material Examples:
There are two types of Material Objects: MaterialClass and MaterialDef. They inherit from the AbstractMESObject. Material Objects do not extend the AbstractMESObject.
On this page:
The MES 3.0 platform implements the ISA-95 Equipment Hierarchy model and object model. The AbstractMESObject implements the objects defined by ISA as well as other useful MES objects. All objects that inherit from the AbstractMESObject share properties, functions and events.
AbstractMESObject:
system.mes.loadMESObject() inherits from the AbstractMESObject
#Get the MES object for a given name and MES object type
obj = system.mes.loadMESObject('Balsamic Vinegar', 'MaterialDef')
#If an MES Object Link object was returned from a scripting or object function, then the following will return the full MES object instance obj = objLink.getMESObject()
(click the diagram to zoom)
Every time a MaterialDef or MaterialClass Object is modified, i.e. adding custom properties, changing a setting etc., the version number of that resource object is updated in the background. When an operation is scheduled, it checks for a corresponding responseMaterialClass or responseMaterialDef object version.
If one does not exist, it automatically create one. This versioning is not part of ISA-95, however, without it, analysis of historical data would lose the original configuration of equipment, personnel and materials.
This object is used to group material into a category. It can have MaterialDef or other MaterialClass objects as children. Defining production tasks for each specific material, is very tedious. A better method is to organize the material into categories (or classes using ISA-95 terms).
Consider receiving raw materials at a dock. Defining a task to receive each type of material would be painful and difficult to maintain. Instead all materials that maybe received can be added to a 'Raw Materials' class. Now when an operator receives material, the operation will prompt them for the specific material that must belong to the 'Raw Materials' class. Only one receive operation has to be defined which is much easi
To call MaterialClass and MaterialDef objects, use getMESObject.
The MaterialClass object inherits the AbstractMESObject properties and methods, but does not extend them.
Material Definition objects are used to define materials that may be consumed or created throughout the manufacturing process. This can include raw materials, sub-assemblies, finished goods, scrap material and consumables. The MaterialDef object inherits the AbstractMESObject properties and methods, but does not extend them.
Material Definition and Material Class objects are created using MES Object Editor component and OEE Material Manager - Vision component. See creating materials page for more details.
ResponseMaterialDef and ResponseMaterialClass objects are automatically created by operations and are used for traceability analysis.
The following script function is used to create these objects.
# Create Material Class - Bulk Nuts
mat_class = system.mes.createMESObject('MaterialClass')
mat_class.setPropertyValue('Name','Bulk Nuts')
system.mes.saveMESObject(mat_class)
mat_class = system.mes.loadMESObject('Bulk Nuts','MaterialClass')
print "Created Material Class Name: %s" % mat_class.getName()
mat_list = ["Bulk Peanuts", "Bulk Walnuts", "Bulk Almonds"]
# Create Material Definitions under Material Class
# Bulk Nuts
# Bulk Almonds, Bulk Walnuts, Bulk Peanuts
for mat in mat_list:
# Create Material Definition
mat_def = system.mes.createMESObject('MaterialDef')
mat_def.setPropertyValue('Name', mat)
system.mes.saveMESObject(mat_def)
mat_def = system.mes.loadMESObject(mat, 'MaterialDef')
# Add Material Definition to Material Class
mat_class.addChild(mat_def)
print "Created Material Definition %s under %s" % (mat_def.getName(),mat_class.getName())
# Save off Material Class with it's new Material Definition Descendants
system.mes.saveMESObject(mat_class)
# New Material Class - Bulk Nuts
# With children Material Definitons - Bulk Almonds, Bulk Peanuts, and Bulk Walnuts
mat_class = system.mes.loadMESObject('Bulk Nuts','MaterialClass')
>>> True Created Material Class Name: Bulk Nuts True Created Material Definition Bulk Peanuts under Bulk Nuts True Created Material Definition Bulk Walnuts under Bulk Nuts True Created Material Definition Bulk Almonds under Bulk Nuts >>>
This object inherits the AbstractMESObject properties...
The base AbstractMESObject object provides core properties that are common to all MES objects. The values of the core properties are accessed using the getPropertyValue() and setPropertyValue() functions of the AbstractMESObject object.
Name | Type | Description | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Name | read, write | This is the name of the MES object. This name is used when referencing the object. It must be a unique name meaning that no other MES object of its type can have the same name. Naming Characters Allowed Names must begin with a letter, digit or underscore. Subsequent characters may also include spaces and dashes. The following characters are not allowed:
| ||||||||
| UUID | read-only | This will contain the Universally Unique Identifier for each instance of a MES object. | ||||||||
| Enabled | read, write | This property will be set to true when the MES object is active and usable. When MES objects are deleted they are still retained in the database and the Enabled setting is set to false. This is done to maintain past traceability information. | ||||||||
| Description | read, write | An optional setting to give more details for a MES object. |
#Get MES object UUID example:
mesObject = system.mes.loadMESObject("Vinegar", "MaterialClass")
print mesObject.getPropertyValue('UUID')
#Set MES object name example:
mesObject = system.mes.loadMESObject("Vinegar", "MaterialClass")
mesObject.setPropertyValue('Name', 'MyNewObjectName')
This object inherits the AbstractMESObject functions.
These functions can be used with all of the MES Objects.
Create a new MES Artifact property named by artifactName on an existing MES Object, with a provided primitive, Pythonic or Java serializable object as the serializableValue (including strings, integer/real/float/double numbers and Boolean). The new MES Artifact is 'versioned' so each save creates a new version of the artifact (one additional row in the DB per version saved).
Files are also 'serializable' (Artifacts serialize the file as an array of bytes. Add "from java.io import File" to script and use File (fileName) where fileName contains the path to the file, with filename and extension. Refer to the Java Class File page).
createArtifact(artifactName, serializableValue)
String artifactName - the name of the 'versioned' MES Artifact to create. Name will be stored using lower-case letters.
Serializable serializableValue - Any primitive, Pythonic or Java serializable object (including strings, integer/real/float/double numbers and Boolean). Files are also 'serializable'.
MESArtifactProperty - A reference to the newly-created Artifact property.

If versioned=FALSE, only one artifact with the version 0 is created and each save overwrites the previous value. If versioned=TRUE, then the artifact is saved with its timestamp, such that each save creates a new version of the artifact (one additional row in the DB per version saved).
createArtifact(artifactName, serializableValue, versioned)
String artifactName - the name of the Artifact to create. Name will be stored using lower-case letters.
Serializable serializableValue - Any primitive, Pythonic or Java serializable object (including strings, integer/real/float/double numbers and Boolean. Files are also 'serializable'.
Boolean versioned - FALSE means only one artifact is stored and is overwritten on each save. TRUE keeps a versioned copy with timestamp as an additional row in the database on each save.
MESArtifactProperty - A reference to the newly-created Artifact property.

Custom properties can be added to MES objects or even complex properties (such as a material, equipment or personnel reference) of an MES object. The AbstractMESObject Functions method can be used to 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"
addCustomProperty(name, dataTypeName, description, units, productionVisible, required, value)
String name - Name of the custom property to add.
String dataTypeName - Name of the Ignition data type to make the new custom property. Options: Int1, Int2, Int4, Int8, Float4, Float8, Boolean, String, DateTime, Text, Int1Array, Int2Array, Int4Array, Int8Array, Float4Array, Float8Array, BooleanArray, StringArray, DateTimeArray.
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. Note that this value is cast to a string, even if the custom property is not a string.

Add a MES object as a parent to another MES object. MES objects can have children and parents. Depending on the type of MES object determines the types of children or parents that can be added. For example, a material class (MESMaterialClass) object can have material definitions (MESMaterialDef) as children, but material definitions objects cannot have material class objects as children.
Note
When a child is added to an MES object, then a parent reference will be added to the child behind the scenes. Likewise, when a parent is added to a child, a child reference will be added to the parent behind the scenes. This insures if integrity of relationships are maintained.
Add Parent before Naming for Non-Unique Names
Some MES Objects can have duplicate names, such as lines in different areas. However, lines in the same area must have unique names. Ensure that object.addParent() is called before obj.setPropertyValue('Name', 'Non-Unique Name') in any script creating such non-uniquely named equipment that requires distinct parents or paths.

Return the custom properties for the complex property (resource reference) as a Python dictionary. The Python dictionary will contain custom property path, value pairs. Because custom properties can be nested, the path of the custom property is used. 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.Widith" and "Dimension 2.Width".
For response segments, references to resources are created for each lot, person or supplemental equipment. For example, if a segment is started filling tank 1 and then switches to tank 2, then there will be two complex properties. One that has all the information while tank 1 was selected and a second that has all the information while tank 2 was selected. Custom properties can be added to the complex properties that will be unique for the time each tank was selected. If a pH reading is collected for each tank, then the separate readings can be saved in the appropriate complex property. To specify which complex property to access, extended naming is used. Referring to our sample, if we named the material complex property "Liquid", then the extend name for the first entry is "Liquid-1" and the second entry is "Liquid-2".

This method can be used to set custom properties values or create custom properties of an MES object. The format of the customProperties parameter determines if just custom property values will be assigned or custom properties will be created and values assigned.
Because custom properties can be nested, the path of the custom property is used. 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"
Python dictionary
To just set the custom property values, use a Python dictionary for the customProperties parameter that contains name value pairs.
To create custom properties, use a Python dictionary for the customProperties parameter that contains name definition pairs. The custom property definition is a Python list that contains the settings. The order of the setting must be data type, value, description, units, production visible and required. Optionally, the production visible and required can be left out. If they are left out the default values of production visible = true and required = false will be used.

If no script is entered, then the default handler will be executed. To execute the default handler from within the script entered here, add a script line:
#Add custom property when a new instance of a MaterialDef object is created.
obj = event.getMESObject()
obj.addCustomProperty('Width', 'Int4', 'Part Width', 'mm', True, False)
event.runDefaultHandler()
