True or false: A function-block diagram is exclusively used for wiring information.

A function-block diagram is a graphical representation used primarily in the field of automation and control systems, particularly for programming complex control systems such as those involving programmable logic controllers (PLCs). While it can indeed include wiring information, its primary purpose extends beyond simply detailing how components are wired together.

Function-block diagrams illustrate the functional relationships and interactions between different system components or processes, allowing for a clearer understanding of how the overall system operates. They depict various functions, inputs, outputs, and how data flows between blocks, which is essential for programming and troubleshooting control systems.

In summary, while it may contain wiring information, labeling the function-block diagram as exclusively for wiring is inaccurate, as it serves broader purposes in system design, functionality, and operational clarity.
