Display of luminous column LEDS: CONTROL_LEDS function
Introduction It is possible to set the relay status (version 2.1 and above) and the LEDs on the luminous screen of a CCX17 console, then to send them using internal words
(%MWi) as intermediaries. This is the role of the CONTROL_LEDS function.

The table below shows the significance of the different words which constitute the following parameter: Data to send (2 words).
contains a marker of value 16#CC17, indicates the coding of each LED as well as the relay state to send to the terminal.
l l l l bits 0 to 3: green LED status, bits 4 to 7: yellow LED status, bits 8 to 11: red LED status, bits 12 to 15: relay status, the state of each of the LEDS is coded on four bits as follows: l l l l
0000: unchanged LED status,
0001: LED off,
0010: LED on,
1111: LED flashing.
the relay status is coded on bits 12 to 15 as follows: the state of each of the indicators is coded on four bits as follows: l l l
0000: unchanged relay status,
0001: open relay status,
0010: closed relay status.
Example of use The example below shows the values corresponding to the word table %MW0:2
