Abstract
A programming tool has selection means for selecting a plurality of function blocks displayed in a library format, storage means for storing the function blocks selected through the selection means in the order as they are selected, and drawing means, as a plurality of function blocks selected through the selection means are confirmed, for drawing and display the confirmed function blocks in the order as they are selected.
Claims10
A programming tool comprising:
- a selection section for selecting a plurality of function blocks displayed in a library format;
- a coordinate calculation section for:
- calculating coordinates of positions of the plurality of selected function blocks based on the order of the function blocks as selected,
- calculating coordinates of positions of an input pin and an output pin based on attribute information of the selected function block,
- determining based on attribute information of the selected block and the previously selected blocks whether the functions blocks can be connected to each other,
- calculating coordinates of positions of a line connecting the input pin and the output pin of the function blocks when the functions blocks can be connected to each other, wherein the coordinate calculation section does not require a user to specify the position of the selected function blocks or pin connection information;
- a coordinate storage section for storing the calculated coordinates of the function blocks, the input pin and the output pin of the function blocks and the line connecting the input pin and the output pin of the function blocks, and
- a drawing section for drawing and displaying a state in which the selected function blocks are connected, based on the coordinates stored in the coordinates storage section.

A method for programming with a function block diagram, including the steps of:
- selecting a plurality of function blocks displayed in a library format;
- calculating coordinates of positions of the plurality of selected function blocks based on the order of the function blocks as selected;
- calculating coordinates of positions of an input pin and an output pin based on attribute information of the selected function block,
- determining based on attribute information of the selected block and the previously selected blocks whether the functions blocks can be connected to each other,
- calculating coordinates of positions of a line connecting the input pin and the output pin of the function blocks when the functions blocks can be connected to each other;
- storing the calculated coordinates of the function blocks, the input pin and the output pin of the function blocks and the line connecting the input pin and the output pin of the function blocks;
- and
- drawing and displaying a state in which the selected function blocks are connected, based on the stored coordinates, wherein a user is not required to specify the position of the selected function blocks or pin connection information to connect the input and output pins function blocks.
