Classic Ladder Not Loading

When I launch CL i get this error in the terminal.

"Classicladder real-time component not detected"

I cannot find a solution. Anyone know what this means and how to fix it?

You must have classic ladder configured in HAL.
If you do have it configured and still can't get it to launch I guess it might be a QtPyVCP issue.

Posting a copy of your hal file would be helpful diagnosing your problem.

Hey Kurt,

Hope is well, I checked.

Here is the info from my hal that should be be enough.

# core HAL config file for simulation

# first load all the RT modules that will be needed
# kinematics
loadrt [KINS]KINEMATICS
# motion controller, get name and thread periods from ini file
loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS num_spindles=[TRAJ]SPINDLES
# load 6 differentiators (for velocity and accel signals)
loadrt ddt names=ddt_x,ddt_xv,ddt_y,ddt_yv,ddt_z,ddt_zv
# load additional blocks
loadrt hypot names=vel_xy,vel_xyz
# load classic_ladder
loadrt classicladder_rt
addf classicladder.0.refresh servo-thread

My guess is wrong directory. Just happened. Wired.

Kernel....

I never have been able to get toastr messages to work... Lol... Still scratching my thick head. I will though.

ClassicLadder also needs a loadusr command line in a hal file as well for it's user-space functions. I don't see that command listed in the snipit of your hal file you posted. Should look something like this.

There is also the possibility that you could have multiple hal files in your config directory and the one your ini file references isn't actually the one you think it is using and the hal file that is actually used doesn't have the ClassicLadder lines? (Been there, Done that.)
