Dataloggers in Thickness Monitoring

About Dataloggers in Thickness Monitoring (TM)

Dataloggers are data collection devices, which are used to measure and record the thickness of a component. Using the Thickness Monitoring (TM) module, you can:
  • Send data related to a TML to the datalogger.
  • Receive data from the datalogger (after you collect measurement data in the field and record it in the datalogger).
Important: If you are using the GE DMS Go/Go+ device and your company restricts the use of removable storage devices in USB ports, the device may not function as expected. You must request an exemption to the company policy from your IT administrator, such that you are allowed Write permissions to the USB drive. Although the Olympus 38DL Plus device supports USB, it does not store its data in the same way and is therefore not likely subject to the same restriction. If your company restricts the use of removable storage devices in USB ports, the datalogger device may not function as expected. You must request an exemption to the company policy from your IT administrator.
The following dataloggers are supported in TM:
  • GE DMS Go
  • GE DMS Go+
  • GE DMS2
  • Olympus 37DL Plus Ultrasonic Thickness Gage
  • Olympus 38DL Plus Ultrasonic Thickness Gage
  • Olympus Epoch 650

For each datalogger, APM provides:

To use dataloggers, you must install the latest version of the GE Device Service as well as any necessary device drivers.

If you have modified the Public\Meridium\Modules\Thickness Monitoring\Queries\TM Assets query, you must revert the query to baseline or add the following SQL code for piping Asset to the query.

Modify Datalogger Settings

Before You Begin

  • Default datalogger settings are provided by APM. Review these settings prior to making any modifications.
  • Datalogger settings are specific to the user, data source, and browser. If you log in as a different user, switch browsers, or use a different data source, you will need to reconfigure your datalogger settings.
  • When you send data to a GE DMS Go or GE DMS Go+ datalogger, APM creates a folder in the USB drive. Therefore, you must have the Write permission to the USB drive on the machine that you will use to send data.
  • When using the Olympus Epoch 650 device, you must specify the COM port used by the device.
    Tip: To determine the COM port of the device in Windows:
    1. Access Device Manager.
    2. Under Ports (COM & LTP), verify the COM port next to the USB Serial device.

Procedure

  1. Access the TM Dataloggers page.
  2. Select .
    A page containing the datalogger settings appears.
  3. In the drop-down list box at the top of the workspace, select the datalogger whose settings you want to configure. By default, the datalogger that you used previously is selected.
  4. If you want to use the GE DMS Go or GE DMS Go+ datalogger, specify a directory in the File Directory box. Files will be sent to and received from the Meridium folder that is created in the specified directory.
  5. If you want to use the Olympus 38DL Plus Ultrasonic Thickness Gage datalogger device, select the desired File Mode option to send to and receive from the device.
    Note: For sending and receiving measurements taken on the device when the thru coat mode is enabled, this option must be set to Thru-Coat.
  6. As needed, enter values in the remaining fields, and then select Save.
    The datalogger settings are modified.

Results

If you have already selected the assets that you want to send to the datalogger, then the Send To section appears. Otherwise, the Select Assets to Load for Dataloggers window appears, allowing you to select the assets for which you want to send data to the datalogger.

What To Do Next

Send data to the datalogger.

Send Data to a Datalogger

Before You Begin

Procedure

  1. Access the TM Dataloggers page.
  2. At the top of the page, in the drop-down list box, select the datalogger to which you want to send data. By default, the datalogger that you previously used is selected.
  3. In the Send To section, in the Select TMLs pane, perform one of the following steps:
    1. Select to navigate through the hierarchy, and select the check boxes corresponding to the TMLs whose records you want to send to the device. To select all TMLs from an Asset, TML Group, Component, or Band, select the check box next to the item.
    2. Search for a TML using the Search box. Enter the TML ID of the TML that you want to search in the search field, and press Enter. From the list that appears, select the check boxes corresponding to the TMLs whose records you want to send to the device.
      You can also search for Assets, TML Groups, Components, or Bands using their IDs to get a list of corresponding Assets, TML Groups, Components, or Bands containing the search term. If you want to select items at a different level, you must select Apply before entering the next search term.
    Note:
    • For an Asset or TML Group, if there are more than 1000 linked TML records, a message appears, and the TMLs are not displayed in the pane. You can select the check box next to the Asset or TML Group to select all the linked TMLs.
    • Sending TML measurement data for piping Assets, piping components, or piping bands is only supported by the Olympus 38DL Plus Ultrasonic Thickness Gage datalogger device.
  4. Select Apply.
    The selected TMLs appear in the Selected TMLs workspace. For non-piping assets, TMLs are sorted in ascending order of Asset ID, TML Asset ID, and TML ID. For assets that have Piping Rotation enabled, TMLs are sorted in ascending order of Asset ID, Component ID, Distance From Inlet, Piping Band ID, and Position.
    Note: If the total number of TMLs across all the selected assets is more than 5,000, the TMLs do not appear in the Selected TMLs workspace. However, the Confirm Send window appears, asking you to confirm that you want to send all the selected items to the device. For Oracle databases, the above-mentioned limit is 1,000 TMLs.
    Tip: Select to access the Table Settings window, where you can set the column preferences.
  5. Select Send To Device.
    The job status appears in the page heading, displaying the progress of the job.
    • If you are using the Olympus 38DL Plus Ultrasonic Thickness Gage or the Olympus Epoch 650 datalogger device, the Send To Device window appears, displaying the file name, Inspector, and the TML count for each asset whose TMLs will be sent to the device. You can modify the file names if required. In addition, you can select the name of the Inspector taking readings on the device. This value will be used later to populate the Measurement Taken By field of measurements upon receiving readings back into APM. Once all necessary changes are made select Send to send the TML records to the device.
    • When sending data to the Olympus 38DL Plus Ultrasonic Thickness Gage or the Olympus Epoch 650 datalogger device, for each file that is sent to the device, a Datalogger History record is created. Datalogger History records are used to uniquely identify TML records by entity keys rather than by Asset IDs and TML IDs.
    Note: When sending data to the Olympus Epoch 650 device, the device has a limitation that prevents you from sending duplicate TML IDs within the same file (for example, TML Groups with repeated TML IDs). In that case, you must send the TML Groups separately.

Results

If the job is successful, the selected TML records are sent to the device.

If an error occurs, the Datalogger Errors window containing the error messages appears.

If the data related to an asset was already sent to the datalogger previously, a message appears, asking you to confirm whether you want to overwrite the existing data on the datalogger. If you choose to overwrite, the data related to the asset is replaced with the data that you send. If you choose not to overwrite, the data will not be sent to the datalogger.

Receive Data from a Datalogger

Before You Begin

  • Install the GE Device Service on the machine that you will use with dataloggers. If you do not install it, when you attempt to send or receive data, you will be prompted to install it.

Procedure

  1. Access the TM Dataloggers page.
  2. At the top of the page, in the drop-down list box, select the datalogger from which you want to receive data. By default, the datalogger that you previously used is selected.
  3. Ensure that the datalogger settings are correct.
  4. Select the Receive From tab.
    The Receive From section appears.
  5. Select Receive.
    The Select Files to Receive window appears, displaying a list of files that store the measurement data. By default, the check boxes corresponding to all the files are selected. If you do not want to receive the data stored in a file, clear the corresponding check box.
  6. Next to each file name representing the file whose data you want to receive, select the check box.
  7. Select Done.
    The job status appears in the page heading, displaying the progress of the job. If the job is successful, data is received from the datalogger, and the Thickness Measurement Location records appear in the workspace.
    Note: The check boxes corresponding to the Thickness Measurement Location records that contain measurement readings are automatically selected. The TML records that do not contain readings are not selected. However, if you have selected the Allow Measurements to be Skipped check box in Measurement Preferences, all records are automatically selected.
    Note: If you are using the Olympus 38DL Plus Ultrasonic Thickness Gage datalogger, the file name corresponding to each TML record received from the device appears in the FILENAME column. In addition, the Datalogger History records that were created when sending data to the device are updated.
  8. Select the check boxes corresponding to the required Thickness Measurement Location records, and then select Save.
    The Confirm Save window appears, asking you to confirm if you want to save the TML records. To change the measurement taken date for the selected measurements, select the Override Measurement Taken Date from device check box, and then select a date in the Measurement Taken Date box.
  9. Select Yes.
    The job status appears in the page heading, displaying the progress of the job. If the job is successful, the selected Thickness Measurement Location records that contain Thickness Measurements are saved.
    Note: If you are using the Olympus 38DL Plus Ultrasonic Thickness Gage datalogger, and you had selected an Inspector when sending data to the device, that user will be populated in the Measurement Taken By field of any new measurements created against the asset. A Datalogger Mapping for the device’s Inspector field is not required to save the data in APM but is required to displayed in the column in the Receive From grid in APM. The Measurement Taken By will be populated even if the mapping does not exist.

Results

If you have selected the Allow Measurements to be Skipped check box in Measurement Preferences, the selected records that do not contain measurement readings appear in the Create Skipped Measurements window, and allows you to create Measurement Not Taken records.
The following analyses are re-calculated:
  • TML Corrosion Analysis linked to each TML whose measurement data you have received.
  • Asset Corrosion Analysis linked to each asset whose measurement data you have received.
