Hi,

We have two UR10e and they working will be working on quality checking. On of them is picking up the parts, moving and rotating around while the another cobot has a KEYENCE sensor on it and checking the part for any displacement or errors.

At the moment I am trying to write a program to show them how it will work, but i cannot find any information **how can i start both programs from one teach pendant.**  
They connected via ethernet cable and using modbus for sensor program change.

Thanks in advice,  
Levente

Hi @anon65291894,

Welcome to the forum! On one of the robots you shall go to the installation-\>Starup and to the following

- Select the program to start
- Input & edge to trig Auto Start & Auto Initialize
- The Input can either be a general purpose boolean accessible via fieldbus or digital inputs

On the other robot, you shall add a before start where you is triggering the inputs on the first robot.

I hope that will guide you in the direction of a solution.
