    If you can be a bit more specific about what you want to do then we may be able to help further. At the moment it's the best I can do. Hope this helps.

    Depending on the PLC, there might be a module you can just purchase to interface with a load cell.

    Otherwise, I'd start with Googling, "load cell amplifier". Without more specifics we can't do any better than that.

    Check to see if your manuf of PLC has a 4-20ma add on module or unit.
    Most load cells use this communication method.

    I was thinking more on the lines of the manuf add-on that would be an expansion module of the PLC, many manuf offer different option modules for different interface solutions, this then communicates directly with the PLC memory.
