    Hi can anyone tell me if this works. I am using the PLC Mitsubishi F series micro-controller. Here is the program:

    LDI 401
    OUT 450
    K 10
    LD 450
    OR 474
    OUT 474
    LD 406
    OR 475
    ANI 411
    OUT 475
    LD 474
    OR 475
    OUT 430
    END

    Ldi 401 is a normally closed switch.
    450 is a counter
    474= M474
    Ld 406 is a normally open push button.
    475 =M475
    Ani 411 is a normally closed push button.
    Out 430 is a lamp


    Here goes,wil this work:
    The normally closed button X401 will automatically turn on lamp 430 and will not go off. But when the push button X406 is pressed this over-rides the automatic control and the lamp comes on straight away and has a reset button X411 and when this is pressed it will turn off lamp X430.


    Thanks

    Try downloading Internet TRiLOGI from here http://www.tri-plc.com/trilogiintro.htm or LADSIM from here http://www.bytronic.co.uk/ladsim.htm they are both free, allthough the latter is a 20min demo but it is easier to use. I used them both for my PLC course and found them really usefull. You can input your ladder and then simulate it to see whats working and whats not.
