The Big Red Mechmate in Aus

[ozspeedway]

Hi EddyCurrent, good to see you again. I am 80% through your drawings and have it working for the most part. The mains to the 24V circuit works, the mains to 50V circuit work, the E-Stop circuit works, all of these via the PNOZ as per your drawings. It is just these that I have had to think a little more about. Basically each of these boxes do what the buttons on your main control panel do, namely stop the machine, pause the machine and start the machine as well as reset the circuit. Now, I have everything working as per your drawing, that is one of each. My drawing above is taking that and making it into 3 lots instead, each one is a copy of buttons on your main panel. In a standard Mechmate, these do pretty much what your circuit does, "start" starts the job, and "pause" pauses the job. There is no "stop" button on a standard MM but I want to incorporate one. There *is* an E-stop in each on an MM though. The start & pause buttons are controlled via pins on the BOB and are assigned to codes that execute when pressed. I however will be using you brains to run things.

Don't get me wrong, I have a large percentage of your drawings worked out, it has taken me a while but I got there and have run wires :) This last little bit should see the control box interacting with the computer by weeks end just to verify the pushing a button does what it is supposed to.

Oh, and the relay numbers have been incremented by one, I am using 2 contactors instead of one and my main on/off one is now K1.
