Hi Gary,

Sorry I was coaching robotics and had a comp this weekend so I was flat out :) The good news is that I had 2 more teems qualify for states! Okay back to work!?

?

We don't have any real library for semaphores, it's really telling you how you need to architect the system. Let me see if I can make something to show you how I would do it in a screen. But basically we don't allow graphics in the Macro's (Mostly because we didn't see the need and I think this is still the best). How you communicate to the macro's is through registers. The registers are the only way to have thread safe data in Lua to the rest of the system. Having graphics in the Mcodes could and would put the events into the macro's / Gcode thread and we REALLY don't want that! By communicating via registers it will allow you to have your dialog and not have the Gcode interpreter thread plugged up with graphics.

?

Now onto the solution!

?

You need to setup a register in the register conifig dialog:

Mine is at the following path "iRegs0/ToolSettings"

?

So in my M6 macro I would put the following:

local inst = mc.mcGetInstance("M6 Toolchange")
local tchangeReg = mc.mcRegGetHandle(inst,"iRegs0/ToolSettings")
local rc = mc.mcRegSetValue(tchangeReg,"ShowTchangeDlg")

-- Code to wait for the dialog to end
while(mc.mcRegGetValue(tchangeReg) == "ShowTchangeDlg") do
?? ?wx.wxMilliSleep(500)
?-- May want to add some code here in the event someone presses stop or kills the program
end
local ReturnValue = mc.mcRegGetValue(tchangeReg)

-- Continue with the toolchanger and you have the return in the register.

?

?

Now in the screen you can put your dialog in a function and check to see if you need to launch it in the PLC script :

local inst = mc.mcGetInstance("M6 Toolchange Dialog")
if(toolchangeActiveReg == nil)then -- put the handle to the toolchange Osig in the global table
?? ?toolchangeActiveReg = mc.mcSignalGetHandle(inst,mc.OSIG_TOOL_CHANGE)
end
if(tchangeDlogReg == nil)then
tchangeDlogReg = mc.mcRegGetHandle(inst,"iRegs0/ToolSettings")
end

if(mc.mcRegGetValue(tchangeReg) == "ShowTchangeDlg" and mc.mcSignalGetState(toolchangeActiveReg) == 1 && dlghandle == nil)then
?? ?
?? ?dlghandle = YourDialogFunction()-- Remember to pass back something from the dialog so we know it has been done
else
?? ?if(mc.mcRegGetValue(tchangeReg) ~= "ShowTchangeDlg" and? dlghandle ~= nil) then
?? ??? ?dlghandle = nil-- kill the dialog so the garbage collector can get it back
?? ?end
end

?

?

This is all untested and 100% can be changed but I think it clearly shows how I would do it :)

?

Hope that helps!

Ok thanks Brian,

?

I will try them out, by in the screen not sure what screen the frame? The screen load script ?

?

What my real goal was or is, I have a rotary tool changer, I am checking the m6 macro to see if the new tool is in the rack if not the switching to a manual tool change, the dialog was just a thought if the tool not in rack then give the option to manual tool change and continue is the tool is in the tool table an offset it set, or is tool not in the table and or offset not set then jog down and touch off top of part, or the option to use a touch off plate and probe it, leaving the choices up to me hence the frame and buttons..

?

I will most likely need help I am starting to go over my head now… I did try local semaphore = require("semaphore")

but doesn’t seem to be in the library…. And not sure if it was were the directory is located…

?

Thangs Gary

Hi Gary,

What you will need to do is put this code in the screen (where graphics are done). In your M6 set a register to a value that will trigger the dialog in the screen. You will need a spinlock checking to see when your dialog is done (set some other register stating that the Macro needs to continue) . We do have some other tools to hold a macro (mcFileHoldAquire) but it's a bit more advanced (This is the tool that allows the manual tool change to work) and what is also doing the the work for the mcCntlWaitOnCycleStart command. Try that out and tell me how it works for you. If you would like a hand doing it I am more than happy to assist you with the programming. I think this would be a cool router feature :)

?

thanks
Brian

here is an example of the code i have been trying, i wanted to call the frame when doing a tool change, based on checking some registers that may be set..
and only call the frame if need be...

Thanks gary
