REC615 and RER615 Engineering Manual

LED functionality has changed in Ver.2.0. For example, the color of the LEDs when an alarm is triggered can be changed. Therefore LED connections must be reengineered to achieve the desired IED LED panel functionality. In older versions they can be found under hardware but in Ver.2.0 and later versions under configuration as programmable LEDs.

  1. Right-click an IED to be configured and select Application Configuration.
    Locate the LED connections page in Application Configuration. Missing output blocks are represented in red.

  2. Delete old output blocks shown in red.
  3. Drag new LED blocks from the Object Types pane on the left to the Application Configuration pane.
    LED function blocks can be found under Local HMI.

  4. In the Function Block Instance dialog, change the names and execution orders of the function blocks and click Assign.
    The names and execution orders can be edited later by right-clicking the desired function block.

  5. Connect the inputs to the correct LED function blocks by dragging from the variable or OR function block output to the input of the LED function block.
    Rearranging may be required to fit everything on the page.
    Note: Connect to the right input of the LED function block to achieve correct functionality of the LED panel. Typically, LED function blocks are connected to variables or OR function blocks that should already be present; just connect the LED function block inputs to the corresponding variables or outputs of the OR function block.

  6. Save the configuration and click the Validate configuration button from the PCM600 toolbar.
