Grade Control Systems

With Grade Control Systems, the attached EC520 Grade Control Devices (GCDs) allow you to connect to the Cat Grade Web Interface on your asset to troubleshoot and change settings, track device details and locate your asset.

View calibration or design files uploaded to the application and ensure they match files uploaded to specific assets on the site. This helps you remotely verify if the correct files are on the asset.

To access this page, navigate to Manage  > Grade Control Systems.

• Refer to Supported File Types to learn more about what files you can upload to access grade-related data.
• Refer to Tag Files to learn more about what all is needed to view and track Map (Insights) details for grade assets.
         ◦ Tag files created with Universal Total Station (UTS) and Real-time Kinematics (RTK) differential GNSS techniques are supported.

   • Each linked GCD displays its firmware version and helps you track whether any version is outdated.
   • In case of outdated firmware, refer to Grade SIS Documents to understand the compatibility of each version with the respective asset types. You can also contact your dealer, citing the above documents for quicker resolution.
            ◦ You can find devices moved onto a different asset by their serial number and model.

   

6. Asset Status: An indicator is displayed near each asset to convey the following:

   •  : Asset is keyed on.

   •  : Asset is keyed off.

   •  : No status reported from the asset.

   •  : Asset status is not supported

7. Remote Access Status: Indicates the following status of the asset-GCD pairing:

   • Online  : Shows that the asset is paired with the GCD and has one of the following operators display models, which can be remotely accessed: 

     • TD520

     • TD540

     • EC520

   Even if one of the two devices mentioned is available, the status shows as Online. 

   
   • When an asset shows as Online, the status also indicates whether none, one or both remote access devices (TD5XX display and EC520) are available.
   • There may be a delay of up to 10 minutes before GCD displays Online after an asset key is turned on.

   1. Click Online  .

      

      • Remote Access pop-up opens and displays the following:

        • Grade Control Display

          
          The Grade Control Display option is enabled only for assets equipped with a compatible and supported operator display.

        1. Select the Grade Control Display option that redirects to the TD5XX operator display interface.

           

        2. Give it few seconds while the remote connection is established.

           

        3. Once the operator accepts the remote-control request. You can do the following:

           • Access workflow pages, configuration panels and settings pages.

           • View all operator-visible information such as task details, cut/fill values, warnings and system status.

           • Tap, drag, scroll and perform all standard touch gestures. You can select menu items, open dialog components and modify input fields.

           • Adjust display layers, measurement values or map-related settings (as permitted by the system).

             

             
             • To access Grade Control Display remote service, ensure that the GCD software version is v2.25 or higher. To know more, refer to SIS . 
             ◦ The ScreenViewer will automatically install a TD540 display when updating to v2.25 or higher.
             1) After the installation, the ScreenViewer must be opened on the display to perform the initial remote access registration.
             2) Upon first remote connection, the user should select the Do not show again checkbox and allow the app access.
             3) See SIS media M0168943 for more detailed instructions for onboard configuration.
             • Only one active control mode session is allowed at any time.
             • Anyone additionally joining in from a remote system will join in View Only mode. 
             • The control mode request times out if not accepted within 60 seconds.
             • If the operator rejects control or the session times out, the system automatically returns to View Only mode.

           • While you can delete .pnt (recorded point) files synced from an asset to a site on the application, the file remains on the asset. You can access the asset remotely to delete the file from there.    
           • To know more, refer to SIS  > enter your asset serial number and grade-specific SOTTA (System Operations, Troubleshooting, Test & Adjust) details. Learn how to verify design, calibration and other files on the Cat Grade Web Interface.

   • Offline  : Shows that none of the grade control devices are currently available for Remote Access. This can occur when:

     • The asset is switched off/keyed off. 

     • The system is unable to determine the asset’s status due to connectivity.

     
     If the device is offline, the connection request won’t proceed.
