Mapping the fault LED to a Digital Output

[Petewalz]

Is there an easy way to turn on a digital output when the robot is faulted on a RJ3 controller . I looked in the Interchange IO and under ES and faulted is not an available item for mapping. How do I get SOP output 3 (Fault LED mapped to DO 10). I am already using the first six DO for hardwired inputs to our PLC so I don't think I can map the entire SOP to the same rack/ slot.

Try to use monitor.

There is a fault UOP output, which always goes high when the fault led is on, you could map that directly to your outputs.

Or you could write a short background program consisting of one line:

Code:

1: DO[1:Fault Map Output]=(UO[6:Fault]) ;

How do you use monitor to turn on a DO?

I agree with nation. i do this when I install stack lights. I turn on the red light output when the fault uop is on, the green output when cycle start uop is on, and then turn the yellow light(completed cycle) on at the end of the main program.

UOP is not configured on our robots.
There is no way to map SOP 3 (fault LED) to a DO?

You can map a single UI or UO to a physical DI or DO pin.

You could try this in bglogic:
IF (SO[3:Fault Led]), DO[1]=(ON)
IF (!SO[3:Fault Led]), DO[1]=(OFF)

Luetin,

Your solution to use bglogic worked perfectly on the three robots that had bglogic.
I have one older robot that does not have BGlogic. Any ideas for this older robot?

I found a hard contact that follows the fault light on a connector behind the power disconnect
so I am OK.

Thanks for the help!
