Hello,
I want use PNCconf and I dont want change the files generated by PNCconf.
The PNCconf prepared in main *.hal file this:
But I need connect this two iocontrol pin.
Now I have to comment it after every modification in PNCconf. It make me mad.
In custom.hal is:
I would need something like a HAL terminal block.

The PNCconf prepared in main *.hal file this:
net tool-prepare-request <= iocontrol.0.tool-prepare
net tool-prepare-confirmed => iocontrol.0.tool-preparedBut I need connect this two iocontrol pin.

In custom.hal is:
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-preparedI would need something like a HAL terminal block.

Not sure, but I don't think there is any technical reason that connecting two signals
cannot be done in hal though the signal name binding gets a bit funny since you have
one address with multiple names...
net tool-prepare-loopback tool-prepare-request => tool-prepare-confirmed
The parser would need to know the readers and writers of the signal or some kind of
directionality would need to be included in the syntax:
copy tool-prepare-request => tool-prepare-confirmed

I did not find command "copy" in HAL documentation.
I thought aboat my problem, and I will solve the problem by and2 in custom hal.
setp and2.0.in1 1
net tool-prepare-request => and2.0.in0
net tool-prepare-confirmed <= and2.0.out

Will this work? Or this is example for new posibly functionality?copy tool-prepare-request => tool-prepare-confirmed

No, there is no copy command, I was just suggesting a possible syntax to connect signals

In your custom.hal, which will never be overwritten, add:
This deletes the existing two signals(which un-nets the pins) then makes a new connection.
delsig tool-prepare-request
delsig tool-prepare-confirmed
net tool-prepare-loopback iocontrol.0.tool-prepare => iocontrol.0.tool-preparedThis deletes the existing two signals(which un-nets the pins) then makes a new connection.
