Function

FUNCTION F_CX8090_LED_WD (WD=Watchdog)

Since the CX8080, CX8090 and CX8091 supports different protocols, the two LEDs on the CX8080/CX809x are not used by the firmware. Hence, the user has the possibility to generate diagnostic messages himself, which must then also be documented for the end customer so that he can also interpret these messages. For example, you can use the LEDs to display whether the DHCP server has assigned an IP address to the CX8080/CX809xor, if you are using the RT-Ethernet with bus couplers such as the BK9000, you can display whether all BK9000s are in data exchange. Possible colors are red and green.

The F_CX8090_LED_WD function uses the WD LED on the CX8080/CX809x. Various colors and flash modes can be used here.

FUNCTION F_CX8090_LED_ERR

Since the CX8080, CX8090 and CX8091 supports different protocols, the two LEDs on the CX8080/CX809x are not used by the firmware. Hence, the user has the possibility to generate diagnostic messages himself, which must then also be documented for the end customer so that he can also interpret these messages. For example, you can use the LEDs to display whether the DHCP server has assigned an IP address to the CX8080/CX809x or, if you are using the RT-Ethernet with bus couplers such as the BK9000, you can display whether all BK9000s are in data exchange. Possible colors are red and green.

The F_CX8090_LED_ERR function uses the ERR LED on the CX8080/CX809x. Various colors and flash modes can be used here.
