    Hi, really basic question here...

    I've installed Codesys V2.3 and don't have any standard functions available, only standard function blocks.

    I have tried deleting the standard.lib library and re-adding it and installing all the library files that come with the installation.
    I have also uninstalled codesys and re-installed it.

    Google searches and the help file do not seem to help with this issue either.
    Is there something simple going wrong here!?!?

    Many thanks...

    in what language are you writing so we can give you a direction.
    they are called ST operators not functions
    in ladder it is block with enable

    Hi Shooter, I am mainly using Ladder.

    I need the basic functions like GT, GE, EQ etc. I also need the mathematical operators. And also data operators like MOV.
    I have seen instructions showing these functions in the input assistant as "Standard Functions", however my input assistant doesn't have this option, it only has "Standard Function Blocks".

    I know this is a problem with the libraries, however I cannot find where to download the complete set of libraries. They dont seem to be included in my download from the codesys website. I could write my own functions in ST and use this in the ladder program but this doesn't seem the correct way to do things!

    It is really very simple:
    in ladder insert a block with enable.
    it automatically is a ADD, however when this AND is blue press F2 (assistent),
    then select FBD operators
    on the right side you will see ABS for absolute
    i always use function block with enable as it gives me the opportunity to enable a single instruction, or even complete blocks and programs.
