ISO 10303-239 Representation

An overview of the data to be exchanged by the Task Set DEX has been described in the Task Set: Information Overview section. A more detailed definition of the type of data that can be exchanged using the Task Set DEX is provided in the Task Set - Information Requirements section.

ISO 10303-239 Representation Overview

The following sections provide a detailed description on how to specify a task according to the Task Set DEX specification using ISO 10303-239 PLCS. The Task Set DEX specification is defined using PLCS Templates and PLCS Reference Data.

This description may be further tailored by specific parties by extending the Reference Data defined in the PLCS Reference Data Library.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

A summary of how this data is represented in PLCS is provided in Figure 19, and is expanded in subsequent sections.

Computable Event Based Task Triggers

Computable event based task triggers relates to defined states, e.g. a failure (fault state). The event based task trigger parameter is represented as a State_definition being referenced from the Condition_parameter.

The simplest form of computable event based task triggers contains just one parameter and is represented using the assigning_condition template.

Template instantiation for computable event based task triggers, containing one parameter, shall follow the rules defined in template table: Template #67(Figure 24) below.

NOTE Representation of task triggers that requires advanced logical expressions in terms of e.g. AND/OR/XOR conditions are described in Task Compound Conditions Representation below.

The property that defines the parameter for the computable event based task trigger is represented using the representing_state_type template.

Task End Item Context

Task end item context information includes:

Zone;
Access;
Removal route.

Zone, access and removal route information can be assigned to the usage of a breakdown element within an end item, or to the usage of a task (if the task is to be performed at another location than the installation location for the breakdown element).

NOTE The UML requirements model does not restrict the association of one or more of these types of information to the end item or task usage, nor the number of each type, except that there can be a maximum of one zone where the work is to be performed. Detailed information requirements for the task end item context are defined in the associated UML diagram as part of the Information requirements - Task end item context.

The PLCS representation for task end item context information is described in Figure 25

Figure 25 — PLCS representation of Task end item context

NOTE Note that Figure 25 explicitly covers the case for a simple task definition. However, it can equally be applied to a structured task by replacing the representing_task_simple with representing_structured_task_sequential.

NOTE Templates assigned to representing_task_simple reference parameters ^task_method and ^task_method_version for a simple task, shall be assigned to representing_structured_task_sequential reference parameters ^task and ^task_vn for a structured task.

Zone

Zone information associated with the task can be represented in the following ways:

As an explicit representing_zone_element in a representing_zone_breakdown;
As a code;
As a description;

These alternative ways of defining zone information are represented in different ways in PLCS.

Zone as an explicit zone element in a zone breakdown

The basic representation of a zone and its identification is done in accordance with the following templates:

representing_zone_element, for representing the zone definition/identification;
representing_zone_breakdown, for representation of the zonal breakdown to which the zone element belongs;
representing_part, for representation of the end item for which the zone is defined.

Instantiation of the respective template shall follow the rules defined in the respective template table below:

template table: Template #5(Figure 21), for the End Item;
template table: Template #70(Figure 25), for the type of Zone Breakdown;
template table: Template #71(Figure 25), for the Zone Breakdown Element.

NOTE The template table: Template #5(Figure 21) is defined under Breakdown Element as Product in Focus.

Zone defined as a representing_zone_element may be assigned to either the breakdown element, or to the assignment of the task to the Product in Focus if the task is performed in another zone than the zone where the associated breakdown element is located.

The association between the zone and the task (or breakdown element) under consideration is represented using the assigning_zone template, where the In_zone.zone attribute is associated with the zone element, and the In_zone.item attribute is associated with either the Task_method_version_assignment representing the assignment of the task to the Product in Focus, or with the Breakdown_element itself.

Template instantiation for in zone assignment shall follow the rules defined in template table: Template #73(Figure 25) below.

AP239 Issue (GYL-7)

The ISO-10303-239 1st edition does not support the assignment of In_zone to either Activity_method or Applied_activity_method_assignment (or any of their subtypes).

This has been raised as issue, GYL-7, against ISO 10303-239. The EXPRESS schema has been modified in DEXlib (Long form: dexlib/data/schemas/ap239_arm_lf.exp, short form: dexlib/data/schemas/ap239_arm_sf.exp). These changes will be made to ISO 10303-239 as a Technical Corrigendum at some stage.

Task_element_sequence, i.e. defining a sequence of Task_steps;
Concurrent_elements, i.e. comprises a set of Task_steps to be performed during the time required for the longest task. No specific order is required.

The recommended default representation for a structured task is to use Task_element_sequence. The order of the included Task_steps is determined by it position in Task_element_sequence.elements attribute, which is an ordered list.

The representation of a structured task using Task_element_sequence can be summarized into the following two templates:

NOTE The main difference between using representing_task_simple as described in the sections above, and using representing_structured_task_sequential is that the later requires at least two Task_steps.

The characterizations of a structured task follows the same principles as has been described in the sections above, i.e. the same set of templates and template instantiations are to be used as has been described under the following sections:

Task Definition;
Task Resources;
Task Trigger;
Task End Item Context.

NOTE Templates assigned to representing_task_simple reference parameter ^task_step for a simple task, shall be assigned to representing_task_step reference parameter ^task_step for a structured task.

A structured task may include the following information in addition to the information being defined for a simple task:

Task step identification and categorization;
A task step may refer to another task specification containing the details for the task step to be performed;
Task legal, health and safety advisories;
On/off end item classification;
Task document reference;
Task note / remark;
Resources may be aggregated for the entire task;
Elapsed time may be aggregated for the entire task;
Labour time may be aggregated for the entire task.

NOTE Detailed information requirements for a structured task are defined in Information requirements - Structured task.

The PLCS representation for task structure is described in Figure 26

Figure 26 — PLCS representation of task structure

Task step identification and categorization

Basic overall representation for structured task and its identification is done in accordance with the template representing_structured_task_sequential. A structured sequential task in PLCS is represented by the usage of the following entities:

Task_method, representing the overall Task;
Task_method_version, representing a version of the Task;
Task_element_sequence, representing the sequence for the defined Task steps.

Template instantiation for a sequential task shall follow the rules defined in the template table: Template #81(Figure 26) below.

Representation of each task step is done in accordance with the template representing_task_step. A task step in PLCS is represented by the usage of:

Task_step, representing the Task details.

Template instantiation for a Task step shall follow the rules defined in the template table: Template #82(Figure 26) below.

Task Message

The following section describes how ISO 10303-239 PLCS is used to represent a Task Set message. This is summarized in Figure 33 below.

Figure 33 — PLCS representation of Task Set message

Extracted information should be packaged as a message which is then sent to the recipient. Message containing one or more task specifications is represented as an instance of Message in ISO 10303-239 PLCS. Instantiation of Message is done using the template representing_message. The instantiation of representing_message shall follow the rules defined in template table: Template #105(Figure 33) below.

The following message meta data may be assigned to the Message.

Date time of data extraction;
Sending and receiving organization;
Contract information;

In addition to the message meta data, the content of the message is identified. This is represented by linking Message to the task specifications (Task_methods) via the Content_item_selected entity and message_content_item select.

AP239 Issue (RBN-4)

The Content_item_selected entity and message_content_item select are extensions to the current version of ISO 10303-239 PLCS.

This has been raised as issue, RBN-4, against ISO 10303-239. The EXPRESS schema has been modified in DEXlib (Long form: dexlib/data/schemas/ap239_arm_lf.exp, short form: dexlib/data/schemas/ap239_arm_sf.exp). These changes will be made to ISO 10303-239 as a Technical Corrigendum at some stage.

NOTE A DEX defines one business transaction, e.g. one Task Set exchange. If the business transaction, the message, is required to contain a number of task specifications (which would be the case if e.g. the message is to contain all tasks for an equipment), then this is represented by instantiating multiple occurrences of the Content_item_selected item within the representing_message template.
