Set a FOUNDATION fieldbus device to be a link master or basic device

If a device can be a Link Active Scheduler (LAS), the Link Master Configuration menu option displays in the Service Tools menu. Select Master if you want the device to attempt to be the LAS, or select Basic to prevent the device from becoming the LAS. After you set the option, the Trex unit disconnects from the device.

Setting the device as a link master does not set the device as the LAS. The link master device must follow the process to become the LAS if other link master devices are on the fieldbus segment.

Note: You cannot change the device to be a link master or basic device when a host/linking device is detected on the fieldbus segment. To change the device to be a link master or basic device, use the host system or remove the device from the fieldbus segment and connect it directly to the Trex unit.
  1. Connect to the FOUNDATION fieldbus device.
  2. Tap Service Tools.
  3. Tap Link Master Configuration.
  4. Tap OK when prompted that the device will be restarted after the parameter is changed.
  5. Tap Yes or No when asked if the device is commissioned.
    You cannot make changes if the device is commissioned.
  6. Select Basic or Master, and tap OK.
  7. Tap OK to restart the device and apply the changes.
    The Trex unit displays the Device List.
