Is there a signal where i can monitorate if the robot is enabled on the UR3?

I’m making a plc application where it willl be fully interfacing the robot’s turning on sequence, since from turning on the controller to starting the program automatically.

The only issue is that, i could not find if there is a signal, or UrScript function, where i can see if the robot arm is enabled. I needed this to make the plc wait the robot be enabled to make it start the program and make it run. Since now, i was using a timer after i sent the signal to enable it, to wait it to be enabled and then send the signal again to start the program.

If anyone could help me, i would be grateful!

A way I have monitored ‘alive’ status is putting a heart beat on the robot real time clock. Send the ‘turn on’ command and wait for the heart beat to be satisfied.
