Invert Input Signal on YRC1000

  • Go to Best Answer

    Thanks, that's super helpful. If it would be possible, do you mind posting an example of inverting a signal using the concurrent i/o ladder program? For example, I've tried inverting the logical number #20040, but I keep running into errors whenever I attempt to save it.

    STR-NOT #20040

    OUT #00020

    One of the rules in concurrent i/o is you can't output to the same address twice. You would have to break it out the BMOV (if it's a factory ladder).

    I know a thing or two, because I’ve seen a thing or two. Don't even ask about a third thing. I won't know it.

    OUT #00020 is a General Purpose Input that would be used in a robot job. The ladder maps (or passes) the state of the External Input (2xxxx) to a General Purpose (0xxxx). Not knowing the application (arc, general, motor gun, paint, etc.) I am assuming the address 20040 is mapped to 00020.

    20040 00020
