Yes Johannes,
I want to test the EXT automatic where I can use a generic hmi to select a program from the switch case statement.
And the $IN[3000] is an INT (integer) coming from the hmi to the controller.
So do you suggest I'm going in the right direction.? :)
Thanks

Hi Johannes,
Based on our conversation I have come this far.
So I modified the CELL.SRC and calling the case number from the HMI to run my desired program.
Please have a look and let me know if this sounds valid or any changes required.

Thanks :)

Thanks for the info Johannes very useful.
I will start going through the KRL syntax and keep you posted so you could advice me if I'm going in the right direction.

Hi,

I apologise if I'm being a noob
But could you pls be able to provide any more sample code or setup with what you were explaining before in regards to the wait for and goto statements?

Any help greatly appreciated.

Hi Johannes,
Thanks for your response to my query.

So we were thinking about using some standard IO modules and control the robot controller IO with it.
The HMI would be sending and receiving data through the IO modules communicating with the robot controller.
So in your experience what would be a very reliable and cost effective way to approach this problem?
We are just aimed at offering the HMi to be used for the workers instead of the SmartPad.
And we only want to start/stop the robot operation using the hmi button, where start should start the robot program (only one program used at this stage) and stop should simply bring the robot to home position.

Can we use any intermediate gateway converters between HMi and the robot controller so it might have the gsdml file to support profinet?

Could we use the SRC skeleton file in the wvs to support serial comma by the HMI?

Pls comment on what could be done with this setup.

Cheers

Hi all,
I'm wondering if anyone could provide some advice/guidance on how can I use some KRC4 IO to manually connect to a HMI that does not have a GSDML file? So i could manually connect my HMI to an external IO module to communicate with my Kuka Welding Robot?
The idea is just to avoid using the SmartPad (Teach Pendant) as not many floor workers are aware on how to run the robot in AUT.
Please shed some light on how we could access the KRC4 IO and what IO addresses are needed for this task?
We have ProfiNET as our fieldbus option.
Any help is appreciated.
Thanks
