Dynamically selecting a Position Register

    Hello,

    I'm using a CRX and the built-in "Basic Pick and Place" instruction.

    The instruction only allows P[i] or PR[i] and 'i' must be a number.

    I would like to do something like this:

    R[1] = 41

    P[1] = PR[ R[1] ]

    (setting P[1] equal to PR[41], spaces added here for clarity)

    Then I'll tell the "Basis Pick and Place" instruction to use P[1]

    However, I can't figure out how to use indirect addressing.

    The "code" instruction tells me that P[1] = PR[ R[1] ] is invalid.


    Can someone help me please?

    Thanks

    Thanks. I got PR[R[x]] to work for me.

    As a follow-up, where would I find this information. I finally got my hands on the manuals for the R-30iB controller and the cobot but I can't find anything that would tell me I can't write to a P[] position.

    Do you have any recommendations on where I can find detailed programming information?

    Do you have an account with Fanuc? They are the only people you can officially get documentation from. They are very quick to shut down anyone who tries to post their manuals.


    I would recommend the following manuals to get started:

    • HandlingTool Setup and Operations (MAROUHT9410201E)
    • Operator's Manual (Basic Function) (B-83284EN)
    • Optional Function Operator's Manual (B-83284EN-2)
