The logic for the overall control of the system goes something like this:

    First we created a bank of integer memory for use in sending actuation commands, named N16.
According to the bits in that memory bank that were turned either high or low, the ladder program would be sent to the appropriate subroutine dictated by the master control program.
    Inside of each of these subroutines was the logic for each station to complete its job according to the sensor and actuator status read from the devicenet components.  As far as the specific logic steps to run each station, the file has been included on this page and is very well commented for easy reading.  All stations contain complete logic except for the vision station (#7) and the kickoff station (#8).  The best example of robot/mill station is the first (for the tic/tac/toe game), and the others just need a few lines changed before they will run in the same manner.  Also for the milling station, the feedback of the ascii characters over the rs-232 line is not quite finished, it requires some kind of comparison in order for there to be a "mill finished" signal, which was temporarily bridged by a random bit of binary memory that was manually changed when the game was finished.
    Also in each subroutine are several status bits for feedback to the master control program, an occupied station bit, a busy bit, and a station finished bit,  these allow the master program to monitor the system and dictate what should happen next.
