Hello,

is it possible to select a specific program with the plc and send a signal to the robot to load this selected program?

So i can change the robot program with article change of the Line?  
I dont want to do this with the teach pendant.

Hi @steven.sonne

try to use the Dashbord Server of the UR.

I connected my PLC (Siemens) with the UR and i could send directly strings to the Robot.  
The Robot has to be in “Remote”.

[https://www.universal-robots.com/articles/ur/dashboard-server-e-series-port-29999/](https://www.universal-robots.com/articles/ur/dashboard-server-e-series-port-29999/)

Here you can find a PDF file with all the commands that the robot “accepts”. There are commands for Start/ Stop/ Pause…  
Also from here you can Open/ Load saved Robot Programs.

Hi @prasad.waghe07

Yes.

u change/ load a other UR program by using the command "load\<program.urp\>.

I have one programm thats called (on UR) Micellar\_F4

When i want to open that i have to send following code from the PLC to the UR:

The syntax is super important!  
Otherwise the UR will not understand the command from the PLC!
