Apologies for this as again I'm sure it's been covered but I want to do a simple toggle on/off of a relay connected to Port 2 pin 3 from a hardware button on Port 3 pin 15. Controller is UC300

I've been looking at the macro in this thread "Re-routing input to output in Mach??" but am just going round in circles trying to work it out, not a good day I'm affraid

Would someone please point me in the right direction?

Many thanks.

Does the UC300 have built in modbus similar to the CSMIO or are you just setting the inputs and outputs up in ports and pins in Mach?

BTW your link didnt seem to work so I could not follow to the thread you mentioned.

Thanks for getting back, the link should be http://www.machsupport.com/forum/index.php/topic,29178.0.html if that helps. (Don't think that's the way to do it but should work)

I'm just setting I/O in Mach 3, I don't think the UC300 offers Modbus. I/O is via 5 LPT ports, 2 normal and 3 set to input mode.

Ok something like this in the macropump may work, I am assuming They are set up as Input 1 and Output 1 for the code, so if you are using differnt ones you would need to amend accordingly.


LED = GetOEMLED(852)  ' LED looks at state of Output 1 LED


If IsActive (Input1) And LED = True Then  ' looking at input 1 and LED of Output 1
DeActivateSignal (OutPut1)
Else
 If IsActive (Input1) And LED = False Then
  ActivateSignal (OutPut1)
 End If
 End If

Just checked, that wont work correctly, will have to think about it and hopefully I can work out how to do it.

Hood

Maybe it is working, I am just simulating here and it seems to work most of the time,  so if you get a chance give it a go and shout back if it is not correct.

I have my system hooked up on the bench with motors, switches etc. all connected so can try it without any fear of damage, but just so I don't mess this up I'm assuming this to be correct if I use Input 1 and Output 5

LED = GetOEMLED(78)  ' LED looks at state of Output 5 LED


If IsActive (Input1) And LED = True Then  ' looking at input 1 and LED of Output 5
DeActivateSignal (OutPut1)
Else
 If IsActive (Input1) And LED = False Then
  ActivateSignal (OutPut1)
 End If
 End If

Am I right?

Yes that is the correct OEM for output 5 LED.

Hi,

don't think its gona work in macropump because you have to create a rising edge of the input.

this may work:

If not IsActive (Input1)  = True Then
  LED = GetOEMLED(78)  ' LED looks at state of Output 5 LED
End If

If IsActive (Input1) And LED = True Then  ' looking at input 1 and LED of Output 5
  DeActivateSignal (OutPut5)
Else
 If IsActive (Input1) And LED = False Then
   ActivateSignal (OutPut5)
 End If
End If







made a small document how it should work, not the easy way, but it's working here.
sorry for the german windows, but you should find them in the english version.

Yes that one seems to work well at least in simulation.
