FBD/LD/IL element function block

Symbol: FBD/LD/IL element function block 1:

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

A function block can have any inputs and outputs.

If the function block is associated with an image file, the function block symbol is displayed within the function block. A prerequisite is that the option Show function block icon is enabled in the TwinCAT options, category TwinCAT > PLC Environment > FBD, LD and IL.

If you have changed the function block interfaces, you can update the function block parameter with the command Update parameters in the menu FBD/LD/IL, without having to reinsert the function block.
