Subject: I/O to BITS

I am trying to control a solenoid to open and close an air chuck. I am using a Konnect board that is connected to the Kflop via Jp8 on the Konnect board to Jp6 on the kflop board. I am trying to utilize 3.3 v from the Konnect board to a relay that would in turn activate a 24v solenoid to open and close an air chuck. My problem is which bits do i match up in tool setup, which terminals on the Konnect board will go with those bits, and on the digital i/o screen in kmotion.exe which output and state will toggle these bits so i can test my hook ups?//

Hi Terry,

See the section: Typical IO Mapping for Standard Single Konnect
http://www.dynomotion.com/Help/SchematicsKonnect/ConnectorsKonnect.htm

in your case the code from the example EnableKonnect.c should work.

    InitAux();
    AddKonnect(0,&VirtualBits,VirtualBitsEx);


After that toggling Bit 48 on the Digital I/O screen should turn on and off Konnect Output #0

You would use Bit 48 in the KMotionCNC Tool Setup.  Normally M3 might turn it on and M5 turn it off.

Ok, i found the example program enableconnect.c. I push the compile/download/run button.  When i toggle virtual bit 48, i get a light beside of output  -0- on the connect board. I have a meter hooked to the ground on the kflop board and the other lead on output +0. I still dont get any voltage. I verified 3.3volts coming into the konnect board via pin 3 on jp8. Also verified the ground on jp8 on pin 8 and 9.  Am i doing something wrong?

Hi,

the outputs are all opto-isolated, which means the 3.3V used by the Konnect is isolated from the output terminals. The easiest way to think of each output, is like a very small relay.

Depending on your solenoid current requirements, you may be able to control it directly from the Konnect output, which is rated to 30V at 250mA. If you do control it directly, remember you will need to also add a flyback diode to protect the Konnect opto-isolator from the surge of the solenoid being de-energised, the as you would if using a relay.
Details can be found at http://dynomotion.com/Help/SchematicsKonnect/ConnectorsKonnect.htm if you scroll down to "Opto Isolated Outputs".

Tom, if you're reading this, the picture of the Opto outs has the caption, "Input Bank Commons", which I suspect is not the correct caption...

Hi Terry,

Its hard to communicate when we don't know what your background and skills are.  Do you know basic electronics?  Would you know how to wire up a battery,  a switch, and a light bulb?  The Konnect Output is much like a switch.  Or as Moray tried to explain a relay contact.  If you put a light switch on the table and connected a voltmeter to the switch terminals would you expect to read any voltage with a voltmeter as you toggled the switch on and off?  You must use the Konnect Output in a circuit.

Great.  Thanks for your patience and persistence. 

If you are driving a Relay with a coil make sure to add a reverse diode across the coil.  Current Flow in a coil is analogous to the momentum of a freight train.  Attempting to stop the current flow instantly is like trying to stop a freight train with a brick wall.  The negative force generated is huge (big spark).  The diode is similar to adding a loop in the train tracks where the train can circulate until it coasts to a stop.
