FBD/LD/IL Element: Box

Symbol:

A box and its call can represent additional functions, for example IEC function blocks, IEC functions, library function blocks, or operators.

A box can have any number of inputs and outputs.

If the box also provides an image file, then the box icon is displayed inside the box. The requirement is that the Show box symbol option is selected in the CODESYS options, in the FBD, LD and IL editor category.

If you have changed the box interfaces, then you can update the box parameters without having to re-insert the box by means of the FBD/LD/IL → Update Parameters command.
