Object Tree Overview 4.2

In ePVS, your plant is broken down into a hierarchy of manufacturing categories.
The Factory Plant defines the organizational tree down to the component level. The top 3 levels (Areas, Lines, and Stations) are used to organize the tree into a meaningful and friendly navigation structure. The lower 2 levels (Assets, Groups) are the data objects.

Object Tree Descriptions

AREA 

The Area of the Plant where a particular assembled part is built (example: RWD and FWD Transmission Assembly Areas).

LINE

A section or place of the Area that is responsible for assembling a part of the assembly (Example: Internal and External parts assembly Lines).

STATION

A Station within the Line that is responsible for the collection of Assets (Example: Gear build, valve body, and torque converter build Stations).

ASSETS

Assets are used to define a repeatable set of motions/activities (Groups) that have defined Start and End signals (Example: Builds the Valve body and inspects/quality check assets).

GROUPS

A Group is a collection of OPS (individual motions/event data objects). Assets are a collection of Groups that describe a particular sequence of events that comprise one complete cycle for the Asset (Example: When a part enters On-Deck, then Part is present On-Deck, signal to show OP is complete).  
Select the Object Tree button located next to the Customer/Insulation/Plant button. For information on the Customer/Insulation/Plant, click this Link.
The object tree window will open displaying all the available areas based upon your selection Plant selection.
Select the > drop-down box next to each object to further expand the areas. Continue to expand areas until you reveal the object you desire, then click on the Object to open the cycle browser. This will open the browser window with the last 100 cycles.

Object Status Indicators

Paypoint 

The indicator Paypoint (Pay Point) refers to the result of an actual product of a line when the last object is completed. 
When the setup of a Pay Point is made, it is generally placed at the ASSET level objects. After it is set, ensure that the higher-level objects Pay Points are selected as well. Without performing this critical setup, the function of the Pay Point will not work.

Blocked

The object completes its work and is waiting for downstream objects to finish so the finished part can move out of the object.

 

Starved Point

The overall time the object is in a starved state. The object completed its job, and the produced part has exited the object. The object is waiting for the next part to start working.

 

Has a Layout

This indicator shows that this object has a layout completed in the dashboard section of the ePVS module.

Once you've navigated to the object of your desire, you can now click on any of the modules to view the graphical and other informational data from one of the many modules of the ePVS Browser.

 

 

 

Click on the Cycle Browser button, on the Main Menu (left side), or the Quick Links to the right of the Object Tree to go to the Cycle Browser. Once selected, the Data Browser will open with the Last 100 cycles in the History Display Browser, displayed for that object selected.

Plant/Factory

The Factory/Plant Object can be named after the Customer Name (Or Accepted Abbreviation) or Plant Name (Or Accepted Abbreviation). It is the highest-level object. When naming, keep it between 5 and 15 characters - no more than 20.
WTM A _ Bodyshop _ 6X_S010_050 _ S020_ S020FX1 _ ADV PIN 1 _ PIN 1 ADVANCED
The FACTORY for this example is the fictional Willison Truck Manufacturing (WT Mfg.). They make several versions of trucks. In this example, there are two factory locations, Arizona, and Utah. Selecting a Factory name could use the initials of the company name and the location if there are multiple sites.

  • WTM A (Willison Truck Manufacturing) + A (Arizona). WTM A.

  • WTM U for the Utah Factory.

 

 

AREA

The Area Object is a Customer Designated Area, such as a Bodyside, Bodyshop, or another large part of a whole product. The Area Object is the "Child' under the Plant object. When naming the Area Object, it can be more than 1 - same punctuation rules as Plant. Example, Bodyshop and Framing.
 
Area - WTM A  Bodyshop  6X_S010_050 _ S020_ S020FX1 _ ADV PIN 1 _ PIN 1 ADVANCED
In this factory, the manufacturer will have several areas that could be monitored. The Areas would be separated by the types or parts of a product they produce, such as Bodysides, Framing, Painting, Bodyshop, etc. For this, we would specify a particular AREA.

  • Bodyshop

  • Bodyside

  • Framing 

 

 

LINE

The Line Object is a Customer Designated Line Segment and Style of Station range, such as a 6X S010 or 6X S010-S050 (if there are multiple stations in one or more of the Line Objects). The Line Object is the "Child' under Area object. When naming the Line Object, it can be more than 1 - no more than 20 characters, stating a segment and a range of station (element) in the Line.
 
LINE Object - WTM A _ Bodyshop  6X_S010_050  S020 _ S020FX1 _ ADV PIN 1 _ PIN 1 ADVANCED
In the Bodyshop AREA, they may have multiple LINES. Each LINE has an abbreviated designation for them and the STATION or STATIONS in the LINE Name. If a line has two or more STATIONS within the LINE, you will want to use the LINE Number (6X) + the STATIONS (S010_050) included in that LINE. Note the examples below.

  • BA010_050

  • 6X_S010_050 (this line has multiple stations)

  • UBODY_C01 (this LINE has only one station) 

 

 

STATION

The Station Objects are Customer Designated Station number, usually in reference to the 2nd part of the Line Objects name (aka S020 which is part of the 6X S010-S050 Line Object or S010, S020, S030, S040, and S050). The Station Object is the "Child' under Line object. When naming the Station Object, there can be more than 1, to try to keep it around 10 characters.
 Station - WTM A _ Bodyshop _ 6X_S010_050 _ S020 _ S020FX1 _ ADV PIN 1 _ PIN 1 ADVANCED
The STATIONS are the Child objects located in each LINE Object. Within the 6X S010-S050, there would typically be 5 (S010, S020, S030) stations in each LINE Object:

  • S010 

  • S020 

  • S030

  • S040

 

 

 

ASSET

The Asset Objects are Customer Designated Asset Name and a description of the type. It consists of Main Stations, Robot Stations, and Fixture Stations. Main Stations are Customer Designated Station Number. Robots are Numbers, Robot Number, and description. A Fixture is a station number. The Asset Object is the "Child' under Station object.
When naming the Asset Objects, they can be more than 1 - same punctuation rules as plant.
 
Asset - WTM A _ Bodyshop _ 6X_S010_050 _ S020  S020FX1  ADV PIN 1 _ PIN 1 ADVANCED
The ASSET Object naming is a combination of the Station Name + Type of station it is (Main, Fixture, and Robot). You would name as follows:
S020FX1 (Station Name (S020)+ Fixture(FX) + Number(1)

 

  

 

Group

WTM A _ Bodyshop _ 6X_S010_050 _ S020 _ S020FX1 _ ADV PIN 1  PIN 1 ADVANCED_
The Group Objects are Tooling Group – [Unit Type] [Unit Type Number# ][Unit Type Motion] Model Abbreviation. The Group Object is the "Child' under Asset object. There can be several Group objects, so use no more than 20 characters. 
Group Objects naming is typically made up from 2 group types (Tooling and Robot Motions) and 3 descriptors (Unit Type Motion, Unit Type, and Unit Type Number).Tooling Group (Example - ADV PIN 1  
[Unit Type Motion] + [Unit Type] + [Unit Type Number#]

OPS

The OPS or Operations objects are the "Child" objects of the Group Object. There may be at least 1 but no more than 16 for any one Group –use no more than 29 characters when naming the OPS. The naming of a Tooling Group OP typically consists of a Unit Type Abbreviation, a Unit Number, and a Unit Type Position Abbreviation.

Tooling Group OP

The naming of a Tooling Group OP typically consists of a Unit Type Abbreviation, a Unit Number, and a Unit Type Position Abbreviation. The full spelling can be used, however, if the OP has a long descriptor, it may be advisable, to use an abbreviation.

Robot Motion OP

The OP also uses Robot Motions stated as Work Type Position in the naming. These are "AT" and "CLEAR OF".
