Production OEE Data Collection Version MES 15.74 Revision E1  

 

OEE 

OEE Data Collection provides two ways for plants to collect Data from asset activity:  

 

1. Report production data (Asset event/downtimes, work time) manually in the OEE Data Collection module.
2. Collect production data automatically using the OEE Configuration tools, 42Q’s API, and a preferred client. 

 

To access OEE Data Collection go to: Production > OEE Data Collection and the following main screen will appear.

Report Asset Event

In the Report Asset Event portlet, Shop Floor Operators manually add asset events running, setup, idle, spare, in maintenance, calibration, scheduled downtime, and unscheduled downtime due to asset malfunctions as well as routine stoppages (such as parts in transit or lunch breaks). This data expresses the Availability component of  OEE Configuration.   

When an asset experiences stoppages, for any reason, a signal is sent to the MES database, the time is recorded in the system, and a work order is created. When the asset is once again running, the work order is closed and corresponding timestamps are recorded.   

Keep in mind that uptime and downtime timestamps are dictated by the up/down intervals defined in the Up/Down Threshold submodule of OEE Configuration. This allows for a grace period during which the signal is not sent to the MES, based upon machine parameters and production expectations. 

TIP: Do not forget to set Up/Down Thresholds so Work Orders are not triggered during scheduled downtimes (e.g. setup).

Attention: Plants operating OEE Configuration without an auto PLC or FUJI interface must manually record stoppages due to a plant’s regular workflow (e.g. lunch breaks, waiting for parts) in Report Work. 

Engineers will then use the Report Asset Event tool to manually record the root cause for each downtime event.

 

Note: Root Causes are reported in Data Collector for all interface types.  

 

In the Report Asset Event module, operators can report details about their shift to include the following:  

• Work Time: The operator enters the beginning and end of their shift. This data represents the Performance variable of OEE Configuration
• Finished Quantity: The operator enters the total number of units produced
• Good Quantity: The operator enters the number of first-time quality units produced

Taken together, Finished/Good Quantity represents the Quality variable of OEE Configuration. 

 

 

Report Asset Event

To record an asset event due to regular plant workflow:   

1. Select the “+” icon on the top menu bar. 
2. A pop-up window displays: Report Asset Event.

3. Complete the following fields:

• Asset: Select the Asset.

 

Note: The system allows for a complex search: Input at least 4 characters to locate the asset.  

 

• Status:  Select the status of the asset. Options are: Running, Unscheduled Down, Scheduled Down, Setup, Idle, Spare, In Maintenance, and Calibration.

 

Figure 3: Asset Status

• Running - It is used to up the asset without location, shop order, part number or it can record the period shift Finish Qty/Good Qty(optional).
• Unscheduled Down - It is used to record the asset unscheduled downtime event.
• Scheduled Down - It is used to record the asset scheduled downtime event.
• Setup - It is used to record the production line/asset setup time during the preparation.
• Idle - It is used to record the asset idle time when the asset is up and running, but it does not produce any product.
• Spare - It is used to record the asset non-schedule time. 
• In Maintenance - It is used to record the maintenance time when the maintenance team performs the asset maintenance.
• Calibration - It is used to record the calibration time when the maintenance team performs the asset calibration.

 

• Start Time/End Time: Select the date of the asset event using the drop-down calendar. Then select the time using the adjustable timestamp at the bottom of the calendar form. (Note: If the event time corresponds to real-time, there is no need to manually select the time - the system records real-time when the date is selected.)
• Reason: Select the reason for the asset event from the drop-down menu provided. 

 

Note: Reasons are configured within the Asset configuration module of the CMMS (Computerized Machine Maintenance System) under the Problem category. This association links Asset (machine) problems with their corresponding downtimes.  

Note:  If users report Assetrunning events, they can input the Shop Order, Part Number, and Location. When inputting the Start Time and End Time, the Finished QTY and Good QTY will display.

 

4. Once the information has been successfully entered, select Next.

Report Reason and Report Downtime Per Interface

Once the repair is complete, users must report the Reason for the asset malfunction.  

The type of interface used by each individual plant to gather data will determine whether downtimes and reasons are sent automatically by the MES, or recorded manually by Shop Floor Operators. The following rules apply:  

• Fuji Host Interface: Downtime and Reason automatically retrieved from Fuji; no human involvement.
• Auto PLC Interface: Downtime and Reason automatically retrieved from PLC; no human involvement.
• Semi-automatic PLC Interface: Downtime retrieved from PLC; Reason must be entered by Operator.
• No machine Interface: Downtime and Reason must both be entered by the Operator.

5. Select the checkmark screen at the bottom to generate the new split downtime event record.

 

Root Cause 

The Root Cause of the downtime problem is recorded by an engineer after the asset is repaired. Root Causes are based on the Reason recorded as well as a thorough inspection of the stopped asset. Root Cause information is used to compute OEE Configuration Trend Reports: Trend reports provide valuable insight into productivity. All plants are required to input Root Causes so that accurate and useful OEE Configuration data is available.

 

1. To add a Root Cause, select the desired asset down the record by highlighting the line of data.
2. Select the Root Cause icon.
3. The Root Cause window will display.
4. Select the + button to add the root cause to the selected downtime record.

Automatic OEE Configuration Data Collection

As noted in Report Reason for Machine Downtime Per Interface, OEE Configuration variables (Performance, Availability, and Quality) can be collected manually or automatically, depending upon the type of interface used by the individual plant. This section describes how to set automatic interfaces.  

 

The following interfaces are used to auto-collect production data:  

• MES 101 interface
• Fuji interface
• PLC/Rapid IIoT Gateway interface

 

The below diagram illustrates the major data sources required to calculate OEE Configuration automatically; manual entry and manual correction are still supported at OEE Configuration Data Collection.   

 

Figure 25: Major data sources required to calculate OEE Configuration

 

MES 101 Integration

MES 101 allows OEE Configuration to gather Performance & Quality data from MES automatically, thus avoiding possible human errors resulting from manual entry. The process saves labor time and ensures data (e.g. Finished Qty, Good Qty, Target UPHs, shop order, Start/End Intervals, etc.) is accurate and up-to-date. The automatic data retrieval also reduces the need for operation training, thereby simplifying implementation, and reducing costs.

 

Configuration Steps

In order for the system to get the Production data and target data, users must map the Asset to the Location in the OEE Configuration system (Shop Floor Control > Configuration > CMMS Asset > Asset Mapping).   

1. Go to: Shop Floor Control > Configuration > CMMS Asset > Asset Mapping.
2. Add Client ID andLocation Name.
3. Select Asset ID with the drop-down feature.

Note: Mapping configuration is completed only once.
 

Figure 26: Shop Floor and Asset Mapping

• Client ID: The Shop Floor ID. 
• Location Name: Enter the MES101 Location. Location maps Asset status to defined target values in order to capture OEE Configuration Quality and Performance data. 
• Device ID: The Device ID for the MES101 Location, such as NetDC, Emulator.
• Asset ID: Asset that is defined in CMMS > Asset.
• Status: Active mapping in the blue tick, inactive mapping in the gray tick. 

 

Fuji Integration - Fuji Host Interface

Factories with Fuji AMEX & NXT machinery utilize theMESAgent application to sync Fuji machine downtime raw data and error codes with the OEE Configuration database. 

The below diagram lists the process that Fuji Interface follows to collect the data.

Fuji Host Interface - the OEE Configuration system can retrieve the machine Up, Down/Reason through the Fuji Host Interface/MESAgent Client automatically.  The Fuji Host Interface up/down, down reason is the same as the PLC up/down, down reason signal which comes from the machine automatically.  When using this approach, the Fuji Host Interface can only be used along with the NXT & Aimex modules. 

Following are the steps to run the Fuji Interface:

1. Install Fuji Host Interface at the production Fujitrax PC. The Host Interface application is included in the Fuji installation CD with installation instructions.
2. Install the MESAgent Client (42q Application) in the production Fujitrax PC. It will keep listening to the machine Up & Down/Reason signals from the Fuji Host Interface and will forward it to the 42Q OEE Configuration system.

Note: The Fuji Host Interface and MESAgent are installed by the Administrator or Support team.   

 

PLC Interface Overview

OEE Configuration application availability of Layer 2 drivers (Kepware) to perform data capture from Machines or PLCs and transfer to 42Q Via Rapid IIoT.

Kepware IIoT will be set up to monitor the downtime reason code tag. Once the machine is down, IIoT will detect the reason code tag value change and send a signal (which includes the reason code and timestamp when reason code changes) to 42Q OEE Configuration downtime process, then 42Q OEE Configuration process will process this signal and mark corresponding downtime record with corresponding problem code mapped to this specific reason code. The following diagram illustrates the configuration steps. 

 

Figure 28: Collect Data from PLC

The OEE Configuration system can retrieve the asset’s Up/Down and Reason signals from a PLC Connection, thus removing the need to record reasons (Report Downtime) and manually enter work time (From/To) and Finished/Good Quality. 

 

PLC Integration Steps

1. Install a third-party middleware (such as Kepware) software to communicate with the PLC and forward payloads to 42Q IIoT APIs.
2. Work with the 42Q automation engineering to test and set up the PLC connection.
3. Set up the machine downtime Error Code (to map Asset’s Problem Code) at the OEE Configuration Configuration module.
4. Once mapped, users may view Downtime Root Cause Analysis Reports, Downtime Problem Reports, Downtime Trend Analysis Reports, and others in OEE Configuration Reports.  

 

Note: Steps 1 and 2 are completed by the Administration or Support team.   

Note: OEE value will be recalculated with the new downtime or performance/quality data.

 

If users fill in the missing new downtime, then the system will recalculate the OEE value based on the new downtime. If the MES101 API is down, the system will try to get the previous OEE Performance & Quality data automatically. If the Target UPH value is missing, the system will recalculate the OEE value again after users correct the value. The backend recalculation job will run automatically. 

 

Glossary

1. MTBF: Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a system during operation.MTTR: Mean time to failure (MTTF), measures the average time between failures.
2. MTTR: Mean time to failure (MTTF), measures the average time between failures.
3. Quality: An OEE Configuration variable that depicts the number of good products divided by the number of bad products. It is commonly referred to as the first pass yield.
4. Availability: Machine Downtime, according to duration. Takes into account all machine downtime including minor stoppages, slow production, and idling. Calculated as: Operation Time/Planned Production Time = Availability.
