  • D0-05DR will not output

    I am somewhat new to plc programming, so this may be a stupid question.

    I was writing a program and testing it as I went along, everything was working as it should. Then for some reason when I made a few changes it would no longer output to any coils. I opened and wrote a test program just to try and get it to output and still no go.

    Here is a copy of the test program I wrote:

    PLC 05

    // Rung 1
    // Address 0
    STR B2.0
    OUT Y0

    // Rung 2
    // Address 3
    END

    // Rung 3
    // Address 4
    NOP


    Thanks in advance

        I often hesitate to propose that type of answer. But rest assured - while I do seem to have a lot of insight into the PLC problems it is primarily because I personally have made the same mistakes (including this one.)

        One of my favorites is being mad that I'm not seeing a value in the PLC changing, tried everything possible to check the hardware only to finally discover that I wasn't online.
