About this task

Each controller has an EOL switch, which, when set to ON, sets the controller as a terminating device on the bus. See Figure 1 for the EOL switch location. The default EOL switch position is Off.

To set the EOL switch on an FX-PCA3611 controller, complete the following steps:

Procedure

  1. Determine the physical location of the controller on the FC bus.
  2. Determine if the controller must be set as a terminating device on the bus.
    Note: For detailed information regarding EOL termination rules and EOL switch settings on FC buses, refer to the MS/TP Communications Bus for the BCPro System Technical Bulletin (LIT-12011908) or FX-PC Series Controllers MS/TP Communications Bus Technical Bulletin (LIT-12011670).
  3. If the controller is a terminating device on the FC bus, set the EOL switch to ON. If the controller is not a terminating device on the bus, set the EOL switch to Off.

    When a controller is connected to power with its EOL switch set to ON, the amber EOL LED on the controller cover is lit.
