and2 in multiple hal files?

Hi guys,

I am trying to keep the hal files quite separated by the hardwares attacted to the machine: pendant, buttons pannel, probes, etc
For this I use multiple hal files that I load in the ini file.
However I ended up in the situation where in a file I have:

loadrt and2 count=4

and in another file I have:

loadrt and2 names=and2.vc

This results in the following error:

and2: already exists

Is there a way to give aliases to and2 so that I can use it in multiple files and keep everything clean?
Or what would be the best practice regarding these components?

I think the solution for this kind of issue is the "TWOPASS" hal file parsing option

I'm not sure exactly how or if TWOPASS works in this situation. But I think the simplest solution is to loadrt all of your and2s in your first hal file. (all the and2 net lines in the 2nd file can stay there. Use a line like this in the 1st file.

Thanks, after doing this and adding names to all and2 and or2 it worked.
Now I ran into another issue:
I have a hal file that wires some external buttons for Run/Step and Pause/Resume
This enters in conflict with the hal file of the pendant VistaCnc that has buttons for pause resume on the pendant.

The error I get is: halui.program.is-paused was already linked to signal program.is-paused.

Is there a way to merge these two files similar to twopass so that they don't conflict each other?

Can you attach the conflicting hal files? Have to see what's going on to find the best fix.

Maybe using the OR component will do what you need, net the two inputs to two svitches and the output to run/ step. Same thing for pause/resume.

Just think about the problem for the moment.
You want to pause the machine when you press button 1 OR button 2

So rephrasing into the language of HAL, you need to connect button 1 and button 2 to inputs on an OR2 component and connect the output from the OR2 to pause the machine in halui.

Rod,
Thank you.
Much better explanation than i can do.

See below the files that are conflicting:
The error I get is: halui.program.is-paused was already linked to signal program.is-paused.

It will also tell you what line the error occurs on.

If the error occurs on the or2 line then you need to delete (or comment-out) the first net.
