Rule

Sub ID a

The Inport block shall be positioned on the left side of the diagram, but can be moved to prevent the crossing of signals.

Custom Parameter

Not Applicable

Example — Correct

Example — Incorrect

Inport block is not positioned on the left side of the diagram.

Sub ID b

The Outport block shall be positioned on the right side of the diagram, but can be moved to prevent the crossing of signals.

Custom Parameter

Not Applicable

Example — Correct

Outport block is positioned on the right side of the diagram.

Example — Incorrect

Outport block is not positioned on the right side of the diagram.

Sub ID c

Duplicate Inport blocks shall be prohibited.

Custom Parameter

Not Applicable

Example — Correct

One Inport block is used.
