Programming
CX8190 52 Version: 1.5
7.2.2 Function F_CX81x0_LED_ERR
Since the CX8190 supports different protocols, the two LEDs WD and ERR on the CX8190 are not used by
the firmware. This allows the user to create his own diagnosis messages. The LEDs can be used to indicate,
for example, whether the CX8190 has received an IP address from the DHCP server or whether devices are
exchanging data.
The function F_CX8190 CX8190 _LED_ERR controls the ERR LED on the CX8190. Various color and
flashing modes can be used here. The possible LED colors are red and green.

activate different program parts in the PLC depending on the switch position.
