Device Matching

When an EtherCAT connection is established, the E-CAT Configuration Tool checks whether the connected devices match those from the selected project. If they do not match, the tool prompts the Device Matching window to start the device-matching process.

Note: The tool compares the device's Index, Vendor ID, Product Code, Alias Address, and Explicit ID. If all match, the device-matching process will not be initiated. If one or more does not match, the device-matching process will be initiated.

To start the device-matching process:

  1. In this example, the tool detects that the first two I/O devices' vendor ID and product code do not match those in the selected project. To match the devices with project I/O, we should swap the sequence order (index) of the found I/Os. Select Start matching.

Note: You can select the Show vendor and product, Show station alias, and Show explicit ID checkboxes in the upper-right corner to view the vendor ID, product code, station alias address, and explicit ID. You can also select the Show input/output length checkbox in the IO field to show each I/O device's input and output length.

  1. You can manually adjust the changes or have the tool automatically match the devices.
    • Manual matching: Select the first I/O in the Project IO field and click to move it down. The devices should now match.

    • Auto match: Select Auto match in the upper-right corner. The Auto Matching dialog appears.
      Match project IOs to found IOs: Select this option to match the project I/Os to the found I/Os. If the vendor ID and product code of a project device are the same as those of a found device, you can select this option.
      Match by their indexes (ignore device information): Select this option to match the project I/Os to the found I/Os based on their indexes, ignoring device information.

  2. Select Finish in the bottom-right corner to return to the main window.
