FB_CX7080_LED_WD

You can use the WD/ERR LEDs of the CX7080 to display the states of the PLC program, communication, or other information.

The function block allows setting the WD LED of the CX7080. The LED has two colors, red and green. If both colors are activated, the LED will be yellow. You therefore have three colors at your disposal. You can turn on the LED and/or make it flash.

To use the LED, the corresponding COM port must be included in the configuration. The RS232 interface is linked to the WD LED.

The function block should be called cyclically. The desired LED mode can be selected or changed using eLED.

	User-specific function of the LEDs Due to the user-specific usability of the LEDs, Beckhoff Support cannot know the meaning of a flashing code and cannot support the customer. Document the function of the LEDs for your customers.

Inputs

VAR_INPUT
    bEnable     : BOOL;                // set TRUE to enable LED handling; Reset in order to reset error
    eLED        : E_CX7080_LED;        // LED flashing mode
END_VAR

Name	Type	Description
bEnable	BOOL	The function block activates the LED as soon as and as long as the input is TRUE.
eLED	E_CX7080_LED	LED mode
