Interact in Java with variables assigned/created in PolyScope/URScript

[GumerCascales]

Hi everyone,

thanks for reading and your time first!!

I am struggled developing my URCap.

My idea consists of creating a HMI screen for a palletizing project, where I have buttons and different combo boxes to change between programs when palletizing or to change some important values for a chosen program.

I have all this info stored in variables created either with PolyScope or URScript lines, like the number of the layers, current box number, etc.

Therefore, I thought that the best option was to create an Installation Node URCap. The thing is, I do not need to use the generateScript() method since this adds the code in the preamble and I want to update the variables in “real-time”/runtime (exactly when pressing the button or changing the value in a text field).

For now, when using buttons to update a variable, this is working well inside the action listener (sending a socket throught the port 30001):

                  "sec progSec():\nwrite_output_boolean_register(2,True)\nend\n"

But when it comes to i.e. showing the variables values in a text field/pane/label, where I need to read also the value set in the variable, I see no way of achieving this.

I have gone through all these posts and the CycleCounter example (here it is updating a variable but for a Program Node development):

Read variables set by assignment

Hello everyone. I want to create a simple popup during runtime that informs the operator what values a few key variables are set to, so they can stop the program if they are set incorrectly. The variables are set using the built in assignment function. Is it possible to implement this feature using a URCap directly? I know how to make the popup, but fetching the values of variables turned out to be more difficult than expected. There is a large document explaining how to make new assignments fr…

Get variable/register value from Java

I need to get the value (in java) of either: A) a general purpose register B) a urscript variable What is the best way of accomplishing this task? I have tried a number of things and they have all ended in failure. Right now I am investigating setting up modbus communication to get the value but I am worried that this too will end in failure. Please advise asap. Thanks

Set Installation Variable PolyScope With Java

Hello everyone, I have an question about variables. Is it possible to set an installation variable True or False with the java code (in a PolyScope program that already exist) which is not created in the Java code? [var_problem] The purpose is to set e.g. variable Start True with the java code. Is that possible? Start is an existing variable in PolyScope and doesn’t need to be created. With regards, DVoortman

Using Variable value in Java

Hi everyone, We want to develop a basic cycle counter, and display the value of the counter on a specific page. I have read the PDF manual “working with variable”, and i have used the cycleCounter sample but i don’t know how to display the variable value on a label. How can i get it ? With a popup it is ok, but i don’t want to use it. Thank for your help.

And I am afraid that using the DataModel I can get only the names of the variables and I cannot update the values. It is not possible to communicate directly Java with the URControl that is using the variables in runtime, or am I mistaken? Can I use the scriptwriter anywhere?

Any help/clarification would be really useful. I am considering using daemon, but I am a newby with daemons.

Do not hesitate to ask if anything is not clear…

Thanks in advance and kind regards!!
