Creating Subgroup Data Collector

The Subgroup Data Collector acquires live data from the data source (for example, DMS) and compiles it into subgroups.

When submitting subgroups without a part or a lot, the Subgroup Data Collector uses existing production assignments to determine the part and lot that correspond to the process. This will only work if there is one production assignment for the process. If there are zero production assignments or two or more production assignments, the Subgroup Data Collector ignores the subgroups.

When submitting subgroups for a process in an idle state (that is, Process State Type = "Idle"), the Subgroup Data Collector ignores the subgroups. If the process is in any other state (for example, Startup or Shutdown), the Subgroup Data Collector will store the subgroups, since these process state types could be for active startup and shutdown procedures with associated checks. If you consider the process to be fully paused or shut down and do not expect to receive data, you should set the process to an idle state.

When adding or modifying a Subgroup Data Collector, the Subgroup Data Collector dialog box opens.

To configure the Subgroup Data Collector, do the following:

General Tab
Under the General tab, you can enable the Subgroup Data Collector, set the unique name, and configure the data destination.
1. To enable the data collector, click the Enabled checkbox.
2. To run the data collector as a service, click to check the Run in Background checkbox.
  
  Do not uncheck the Run in Background checkbox. The prompting functionality does not work in the Subgroup Data Collector.
3. In the Configuration Name data field, type the identification name.Ensure the name is unique and descriptive.
4. To configure the data destination, click and configure the desired destination, as follows:
  - Enterprise Integration System
    
    You can browse to the destination of the IDEF file, which can be subsequently processed by Enterprise Integration System.
    
    Click the ellipsis button (...).
    
    Browse to and click the folder where you want to store IDEF files.
    
    Click the OK button.
  - Enact
    
    After interfacing DCS to Enact, you can deliver data to Enact using a web-based transport.
    
    For more information on interfacing DCS to Enact, please see Configuring DCS for Enact.
    
    When delivering data, the subgroup data collector has the following constraints:
    
    Maximum Number of Measurement Values: 200
    
    Maximum Unique Feature Names: 200
    
    If a single subgroup exceeds 200 features or 200 values, the Subgroup Data Collector creates an event log entry indicating the limitation boundary. The Subgroup Data Collector will attempt to send the data, though Enact may discard it.

Sampling Tab

Under the Sampling tab, you can set when and how often DCS imports data from DMS.

To associate the data collection with a specific DMS item, establishing the circumstance that causes a sample to be taken, click the Add button and then do the following:
1. In the Tag Item data field, do the following:
  1. Click the DMS Item Selection button.
  2. In the DMS Item Selection dialog box, click the desired DMS tag item.
  3. Click the OK button.
2. In the Evaluation drop-down list, click the desired comparison:
  - IS NEW. TRUE if current data collection is new when compared to the previous data collection.
  - <. TRUE if the value in the Tag Item data field is less than the value in the Value 2 data field.
  - <=. TRUE if the value in the Tag Item data field is less than or equal to the value in the Value 2 data field.
  - =. TRUE if the value in the Tag Item data field equals the value in the Value 2 data field.
  - <>. TRUE if the value in the Tag Item data field is not equal to the value in the Value 2 data field.
  - >=. TRUE if the value in the Tag Item data field is greater than or equal to the value in the Value 2 data field.
  - >. TRUE if the value in the Tag Item data field is greater than the value in the Value 2 data field.
  - Is Valid. TRUE if the value in the Tag Item data field is valid for the data type (for example, date data type contains a date, number data type contains a number).
  - Is Blank or Invalid. TRUE if the value in the Tag Item data field is blank or is invalid for the data type.
3. In the Value 2 data field, do one of the following:
  - Type the comparison value for this condition.
  - Type the item name and tag name in this format:
    
    %TAG(Type, ItemName.TagName)
    
    For assistance locating the item name and tag name, do the following:
    1. Click the DMS Item Selection button.
    2. In the DMS Item Selection dialog box, click the desired DMS tag item.
    3. Click the OK button.
4. Click the OK button.

To set the number of measurements that the Subgroup Data Collector will capture for each subgroup, do the following:

In the Piece data field, type the sample size (number of pieces) within a subgroup.

For an IX-MR control chart, set Piece = 1. For an XBar-Range control chart, set Piece >1 and <10.
In the Within-Piece data field, type the sample size (number of measurements) within the piece.

For traditional IX-MR or XBar-Range control charts, set Within-Piece = 0. For a Range-Within (Rw) graph, set Within-Piece > 0.
To define subgroups based on number of values or number of characteristics, click the Advanced button and then do the following:
1. Click the Maximum Values checkbox, and then type the expected value count before DCS creates a new subgroup.
2. Click the Maximum Characteristics checkbox, and then type the expected characteristic count before DCS creates a new subgroup.
3. Click the OK button.

To view examples, see the following:

Subgroup Size Example 1

Piece Count = 5, Within-Piece = 0

	Loc A
Piece 1	25.2
Piece 2	25.4
Piece 3	24.9
Piece 4	25.0
Piece 5	24.8
	24.6

Maximum subgroup size cannot exceed Piece Count.

After collecting the sixth value for Location A (24.6), the Subgroup Data Collector automatically saves the previous values as a subgroup for the Location A test.

After collecting the eighth total value for Location C (10.6), the Subgroup Data Collector automatically saves the previous values as a subgroup for the Location A, Location B, and Location C tests.

To set the Subgroup Data Collector sampling interval, click the Sampling Period checkbox, and then set the interval and unit as follows:
1. In the Interval data field, type the interval value.
2. In the Unit data field, set the interval time measurement (Seconds, Minutes, Hours, Days, Weeks, Months, Quarters, and Years).
To configure a reference point in time (forward or backward) from which to begin counting the interval, click the Reference (Date/Time) checkbox, and then set date and time. For example:
- If you set the reference date/time to 12/14/2000 8:30:00 AM and a 20 minute interval, the Subgroup Data Collector will begin publishing the next time that is 30 minutes past the hour, and then in 20 minutes intervals after that. For example, if you enabled this provider today at 6:45 AM, the Subgroup Data Collector will publish data at 7:30 AM, and then at 7:50 AM, and then at 8:10 AM, etc.
- If you set the reference date/time to 1/31/2020 10:05:00 PM and a 10 minute interval, the Subgroup Data Collector will begin publishing the next time that is 5 minutes past the hour, and then in 10 minutes intervals after that. For example, if you enabled this provider today at 11:00 AM, the Subgroup Data Collector will publish data at 11:05 AM, and then at 11:15 AM, and then at 11:25 AM, etc.
To set when the Subgroup Data Collector collects the next piece and within-piece data, click the Piece/Within-Piece Time checkbox, and then set the interval and unit as follows:
1. Using the Interval data field, set the interval value.
2. Using the Unit data field, set the interval time measurement (Seconds, Minutes, Hours, Days, Weeks, Months, Quarters, or Years).
For example, if you set the piece/within-piece time to 5 Minutes, the Subgroup Data Collector will collect the next piece and within-piece data in 5 minutes.
To set when the Subgroup Data Collector tries to recapture data that it fails to initially capture, click the Retry Time checkbox, and then set the interval and unit as follows:
- Using the Interval data field, set the interval value.
- Using the Unit data field, set the interval time measurement (Seconds, Minutes, Hours, Days, Weeks, Months, Quarters, or Years).
For example, if you set the retry time to 2 Minutes and the Subgroup Data Collector doesn't capture data at 4:00 PM, it will attempt to capture data again at 4:02 PM, and then at 4:04 PM, and so on, until it successfully captures data.
To switch the Subgroup Data Collector to an Idle State after an interval of inactivity (which could trigger a feedback action), click the Idle checkbox, and then do the following:
1. Using the Interval data field, set the interval value.
2. Using the Unit data field, set the interval time measurement (Seconds, Minutes, Hours, Days, Weeks, Months, Quarters, or Years).
For example, if you set the idle interval to 10 Minutes and the Subgroup Data Collector doesn’t collect for 10 minutes, it switches to an Idle State.

To check if a DMS provider supports read requests, please see the provider’s configuration section in the DMS user manual.
- Sampling Example 1
  Every 15 Minutes, Starting on the Hour, Retrying Every Minute on Fail
  1. Starting at 8:00 AM, the Subgroup Data Collector collects subgroup data every 15 minutes (8:00 AM, 8:15 AM, 8:30 AM, 8:45 AM, etc.).
  2. At 9:00 AM, the Subgroup Data Collector fails to collect subgroup data, so it tries again at 9:01 AM, 9:02 AM, and finally succeeds at 9:03 AM.
- Sampling Example 2
  Every 15 Minutes, Starting at Five Minutes Past Hour, Retrying Every Minute on Fail
  1. Starting at 8:05 AM, the Subgroup Data Collector collects subgroup data every 15 minutes (8:05 AM, 8:20 AM, 8:35 AM, 8:50 AM, etc.).
  2. At 9:05 AM, the Subgroup Data Collector fails to collect subgroup data from DMS, so it tries again at 9:06 AM, 9:07 AM, and finally succeeds at 9:08 AM.
- Sampling Example 3
  Every Monday at 8:00 AM, Retrying Every Hour on Fail
  1. Every week, the Subgroup Data Collector collects subgroup data at 8:00 AM.
  2. At 8:00 AM on the fifth Monday, the Subgroup Data Collector fails to collect subgroup data, so it tries again at 9:00 AM, 10:00 AM, and finally succeeds at 11:00 AM.

DCS publishes subgroups with the First Name and Last Name of the Enact Username. For example, if you configure the Username descriptor with admin, which is the Enact username for Adam Minnan, Enact publishes subgroups with Adam Minnan as the user.
    
    If you configure the Username descriptor with an invalid or nonexistent username, Enact create a virtual user that you can't view or edit, and publishes subgroups with that username as the first name and last name. For example, if you configure the Username descriptor with invalid, Enact publishes subgroups with invalid invalid as the user.
    
    If you do not configure the Username descriptor, Enact publishes subgroups with ADC Default as the user (ADC as the first name, Default as the last name, and ADCDefaultUser as the username). For example, if you leave the Username descriptor blank, Enact publishes subgroups with ADC Default as the user.

  1. In the Type drop-down list, click the desired condition type:
    
    Global. Conditions are applied to every data collection interval. If any of the conditions fail, the Subgroup Data Collector aborts the processing until the next data collection.
    
    Subgroup Start. Conditions are applied when the Subgroup Data Collector is waiting to start a new subgroup. If any of the conditions fail, the Subgroup Data Collector aborts the processing until the next data collection. Once the subgroup has started, the Subgroup Data Collector waits for a new piece.
    
    Piece. Conditions are applied when the Subgroup Data Collector is waiting for a new piece. If all of the conditions pass (or there are no piece conditions), the Subgroup Data Collectoreither waits for another piece, starts waiting for another within-piece, or automatically saves the subgroup if all pieces have been collected.
    
    Subgroup End. Conditions are applied if subgroup information exists after Piece or Within-Piece processing. If all of the conditions pass, the Subgroup Data Collector automatically saves the subgroup, even if all pieces and within-pieces have not been collected.
    
    Subgroup Save. Conditions are applied when this condition is met, saving a partially-collected subgroup. For example, if the part provided by the source data stream changes, the Subgroup Data Collector can save the current subgroup before processing the new part data.
  2. In the Tag Item data field, do one of the following:
    
    Type the item value.
    
    Type the item name and tag name in this format:
    
    %TAG(Type, ItemName.TagName)
    
    For assistance locating the item name and tag name, do the following:
    
    Click the DMS Item Selection button.
    
    In the DMS Item Selection dialog box, click the desired DMS tag item.
    
    Click the OK button.
  3. In the Evaluation drop-down list, click the desired comparison:
    
    IS NEW. TRUE if current data collection is new when compared to the previous data collection.
    
    <. TRUE if the value in the Tag Item data field is less than the value in the Value 2 data field.
    
    <=. TRUE if the value in the Tag Item data field is less than or equal to the value in the Value 2 data field.
    
    =. TRUE if the value in the Tag Item data field equals the value in the Value 2 data field.
    
    <>. TRUE if the value in the Tag Item data field is not equal to the value in the Value 2 data field.
    
    >=. TRUE if the value in the Tag Item data field is greater than or equal to the value in the Value 2 data field.
    
    >. TRUE if the value in the Tag Item data field is greater than the value in the Value 2 data field.
    
    Is Valid. TRUE if the value in the Tag Item data field is valid for the data type (for example, date data type contains a date, number data type contains a number).
    
    Is Blank or Invalid. TRUE if the value in the Tag Item data field is blank or is invalid for the data type.
  4. In the Value 2 data field, do one of the following:
    
    Type the comparison value for this condition.
    
    Type the item name and tag name in this format:
    
    %TAG(Type, ItemName.TagName)
    
    For assistance locating the item name and tag name, do the following:
    
    Click the DMS Item Selection button.
    
    In the DMS Item Selection dialog box, click the desired DMS tag item.
    
    Click the OK button.
  5. To view examples, see the following:
    
    Condition Example 1
    
    Line is Active, Scale Value > 20, Scale Value is a New Value
    
    In this example, data collection only occurs when the following three conditions are met:
    
    AssemblyLine1.IsActive value does not equal zero (0). This indicates the line is currently running.
    
    AssemblyLine1.Scale1.Reading value is greater than 20. This indicates the product is loaded on the scale.
    
    AssemblyLine1.Scale1.Reading timestamp is new. This indicates the scale has submitted a new reading since it was last read.
    
    Condition Example 2
    
    Line is Active, Scale Value > 20, Scale Loaded with New Part
    
    In the example above, DCS might save multiple subgroups for the same part, if the same reading is transmitted more than once while that part is loaded on the scale. To insure a new part has been loaded on the scale, you can configure the scale reading as a Value rather than a Time Stamp, as follows:
    
    AssemblyLine1.Scale1.Reading value is new. This indicates the scale has submitted a new reading since it was last read.
2. Click the OK button.
  
  To (Undefined variable: Snippet.Action) conditions, click the desired condition, and then click the (Undefined variable: Snippet.ButtonName) button. To (Undefined variable: Snippet.Action) conditions, click the desired condition, and then click the (Undefined variable: Snippet.ButtonName) button.
Feedback Tab
Under the Feedback tab, you can configure the Subgroup Data Collector to trigger a read request, allowing it to notify DMS when it is ready for published data, OR send information back to the data source after satisfying a specific condition, whether the source is an OPC server, PLC, or some other equipment.

The Subgroup Data Collector actually writes the value to the selected DMS item, which means the DMS item must be writable.
Data Source Configuration
OPC Server. If the source of the DMS Item is an OPC Server, the Subgroup Data Collector posts the value to the OPC Server, which will subsequently post the value to the originating equipment, such as a shop floor PLC.

Grid Data Provider. If the source of the DMS Item is the Grid Data Provider via serial port or TCP/IP, the Subgroup Data Collector posts the value through that port.

Counter Provider. If you click the Writable checkbox in the originating Counter Provider, the Subgroup Data Collector posts the current counter value back to the Counter Provider, allowing the Counter Provider to track the most recently transmitted value.

[All Other Providers]. If you set the Feedback Type data field to Set Item Value for any other provider (for example, Bridge Provider, Clock Calendar Provider, Clock Events Provider, etc.), the Subgroup Data Collector ignores the setting and will not send any values back to the originating provider.
1. To add a feedback configuration, click the Add button and then do the following:
  1. In the Send Feedback if drop-down list, click the desired feedback condition:
    
    Data Collector is Enabled. Processes feedback when the Subgroup Data Collector state changes to Enabled.
    
    Data Collector is Disabled. Processes feedback when the Subgroup Data Collector state changes to Disabled or DCS is stopped.
    
    Global Conditions Pass. Processes feedback when the Subgroup Data Collector conditions pass (under the Conditions tab).
    
    Subgroup is Started. Processes feedback when the Subgroup Data Collector begins processing a subgroup.
    
    Characteristic is Processed. Processes feedback when a trigger occurs and the Subgroup Data Collector captures new data.
    
    Subgroup is Saved. Processes feedback when the Subgroup Data Collector saves data.
    
    Idle Time Triggers. Processes feedback when the Idle interval elapses (under the Sampling tab).
  2. In the Feedback Type drop-down list, click the desired type of feedback:
    
    Read Request. Notify DMS that the Subgroup Data Collector is ready for published data, as follows:
    
    Click the DMS Item Selection button.
    
    In the DMS Item Selection dialog box, click the desired DMS tag item.
    
    Click the OK button.
