Hello. I attempt to write simple macro M6 to turn on some outputs. For example if M6 T1 then output 6, fi M6 T2 output 7 and so on. Does any body could help mi with this? I have old lathe and there is turret connected to PLC. This controller works: if signal is active on input 1 then turret goes to position 1. In the same way works with input 2,3 and 4. It seems to be rather easy task, but I have no luck :(

Regards, Marek.

Marek,

Ok, here you go. You will need to Enable "Outputs" 1-4 in mach3, if you are already
using those, just pick other outputs and change them below. there are 20 outputs for
your use.


'==========================================================
'M6Start.m1s

Sub Main()

NewTool = GetSelectedTool()
OldTool = GetCurrentTool()
MaxToolNum = 4 'Max number of tools for the changer

While NewTool > MaxToolNum
NewTool = Question ("Enter New Tool Number up to " & MaxToolNum)
Wend

If NewTool = OldTool Or NewTool = 0 Then
Exit Sub
End If

If OldTool <> NewTool Then

'This section of code will turn on the correct tool number output to the input
'you need on the PLC.

If (NewTool = 1) Then
ActivateSignal(OUTPUT1) 'this output goes from Mach to your PLC input 1
End If

If (NewTool = 2) Then
ActivateSignal(OUTPUT2) 'this output goes from Mach to your PLC input 2
End If

If (NewTool = 3) Then
ActivateSignal(OUTPUT3) 'this output goes from Mach to your PLC input 3
End If

If (NewTool = 4) Then
ActivateSignal(OUTPUT4) 'this output goes from Mach to your PLC input 4
End If
End If

SetOEMDRO(824,NewTool)
Code "G4 P4" 'A pause time of 4 seconds to give your turret time to index
While IsMoving
Wend

'This section of code Turns the Output from Mach off after your turret
'has indexed to the new position.

If (NewTool = 1) Then
DeActivateSignal(OUTPUT1) 'this output goes from Mach to your PLC input 1
End If

If (NewTool = 2) Then
DeActivateSignal(OUTPUT2) 'this output goes from Mach to your PLC input 2
End If

If (NewTool = 3) Then
DeActivateSignal(OUTPUT3) 'this output goes from Mach to your PLC input 3
End If

If (NewTool = 4) Then
DeActivateSignal(OUTPUT4) 'this output goes from Mach to your PLC input 4
End If

End Sub
Main

Thanks a lot!!! I will try this tomorrow morning :)
