Fanuc not running STEP status is in yellow normally in green color

Hi Ahmed

Just press the STEP button on your TP keyboard. It should change the yellow STEP status to green.

Step can be used to go slowly and controlled to your robot program for testing. If you are in STEP mode (yellow) you can press SHIFT+FWD and the program will execute one line of code and stops again. This can be quite useful sometimes!

I can't count the times i've left a robot in step while trying to get the line to auto run

I usually run through a program in STEP mode to ensure I don't fire any outputs when i'm teaching points.

I don't know if this is a system variable or what but a lot of our lines won't even go into auto run mode with STEP mode active on a robot. Some will allow us to go into auto but the robot won't run.

Yes that's totally true. Usually I just forget to deactivate it and realize it the earliest when I'm already outside of the security door

The auto mode should normally also run when step is activated. But it will run just one single line of code and then pause again. I think that if you rerun the auto mode that the next line is run (like the FWD command).

I usually add this to my bg logic programs:

DO[78:In Step Mode]=($SSR.$singlestep)

That way I can put it on an HMI so the operators can figure out why nothing is happening when they start the system and there are no faults ...

The UO enable bit won't be on if the robot is in step.

Also, you can setup your cell start options to just reset step on cycle start.

i want to creat a signal from STEP mode ...To show on PC
How to creat " ($SSR.$singlestep) " this in BG Logic?

HHO,

use this line of code in one of your BG logic tasks. The output will turn on when STEP mode is active.
