LinuxCNC 2.9.2
Mesa 7i96s
We have a hobby lathe that has an interlock for a guard / shield.
Our initial configuration had an estop button and the guard interlock in an estop latch.
Now we would like to allow the guard to be open when the lathe is not in auto / running a program.
For now we have been using a second key for the guard, I would like to avoid that.
I haven't looked into the pins for running a program yet, but my question is more about hal datatypes.
Code:
loadrt mux_generic config="bb2"
addf mux-gen.00 servo-thread
loadrt estop_latch count=2
addf estop-latch.0 servo-thread
addf estop-latch.1 servo-thread
net estop-loopin iocontrol.0.user-enable-out => estop-latch.0.ok-in
setp mux-gen.00.in-bit-00 True
setp mux-gen.00.in-bit-01 estop-latch.0.ok-out
setp mux-gen.00.sel-bit-00 halui.mode.is-auto
net estop-door.ok mux-gen.0.out-bit => estop-latch.1.ok-in
net estop-loopout estop-latch.1.ok-out => iocontrol.0.emc-enable-in
net estop-reset <= iocontrol.0.user-request-enable
net estop-reset => estop-latch.0.reset
net estop-reset => estop-latch.1.reset
net remote-estop0 estop-latch.0.fault-in <= hm2_7i96s.0.inm.00.input-04-not
net remote-estop1 estop-latch.1.fault-in <= hm2_7i96s.0.inm.00.input-05-not
The result error messages I get are:
value 'estop-latch.0.ok-out' invalid for bit
setp failed
Replacing 'estop-latch.0.ok-out' with False for testing
value 'halui.mode.is-auto' invalid for bit
setp failed
According to
linuxcnc.org/docs/stable/html/gui/halui.html#_mode
halui.mode.is-auto is a bit out pin
halcmd show pin halui.mode.is-auto
10 bit OUT FALSE halui.mode.is-auto
I'm not sure why it doesn't work and the error message isn't great. In LinuxCNC it looks like the error message is from
github.com/LinuxCNC/linuxcnc/blob/dc9a98...cmd_commands.cc#L666
Does FALSE from halcmd ouput not equal FALSE in some way? Maybe halui isn't loaded at this point?
Any help / insight would be apperciated. Thanks
Edit: Looking at the error messages again, I realize setp is taking the literal value of the second parameter. Not the value of the pin with that name. Now to see if I can figure it out with net / signals.
