FB_CX7080_LED_ERR
You can use the WD/ERR LEDs of the CX7080 to make the states of the PLC program, communication or other indications externally visible.
The function block enables the ERR LED of the CX7080 to be set. The LED has two colors, red and green. If both colors are switched on, the LED lights up 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 RS485 interface is linked to the ERR LED.
 | 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.
