LED Activation (LEDS)
Use
The LEDs in the C7-613 function keys can be activated from the user program.
This makes it possible, for example, to signal to the operator with an illuminated
LED which key he is supposed to press, depending on the situation.
Transfer
The LED image is updated each time the “HMI API” FB is called. If the C7-613 is in
STOP mode, the LEDs are switched off.
Structure
The LED image is a data area with a fixed length of
two
data words.
Two bits are assigned permanently to each LED in the LED image .
