Led burned?

[Graziano]

Hi everybody!

  I have a cFP-2020 module.  Both in LabView (RT-target) and in max, I'm able to switch on LED 1, 2, 3 and 4 to colour green, but I cannot set LED A to colour RED (input --> 2).
  The other 3 leds work properly, that is, when I set them to "2" they become RED. 

   Did I burn someways LED A RED?

PS.: I already  resetted the device, and all configurtation parameters are the same for the 4 LEDs.

Hi Graziano-

The cFP-20XX User Manual explains on page 3-4 that:

LEDs B, C, and D can be sent values of 0, 1, or 2. LED A should be sent

only 0 or 1. LED A handles a 2 as a 1. The values sent to these LEDs

manifest as 0 = off, 1 = green, and 2 = red.

so your cFP-2020 is working as intended.

Hopefully this helps-

Hi and thanks a lot!
   At a first look I didn't noticed these lines on the manual.... but there's still a problem: when I send "2" to LED A, in MAX (Write function, in I/O data tab) the LED does not switch, that is if it is GREEN keeps GREEN, if it's OFF keeps OFF. So it seems that LED A is not handled as n=0=FALSE, n>0 ==> TRUE.

   Anyway, thanks for your help!

Hi

I tested the led A like you, and i have the same result in Max and with Labview RT. Visibly the state 2 has not effect.

For LED A, 0 = OFF, any integer greater than 0 means ON.

The led is physically only offering the green color, it does not have a red part.

It is working as expected, no worries.

Hi!
  I'm sorry, but my device behaves differently. 0=OFF, 1=GREEN, any other=precedent value (no effect). That's different than 2=GREEN!

Hi,

I agree with Graziano. The 2 has no effect.
