Box Variants

1. Black Box

• Purpose: Used to represent devices or components whose internal workings are either unknown or irrelevant to the schematic.

• Key Features:

  • A placeholder for an undefined or external component.

  • Can be assigned connection points for wiring but doesn’t have predefined functions.

  • Used for abstract representations where detailed internal documentation isn't required.

• Common Use Cases:

  • Custom devices with unknown internal structure.

  • Third-party devices where only input/output connections matter.

2. PLC Box

• Purpose: Specifically used for programmable logic controllers (PLCs) and their associated I/O (input/output) modules.

• Key Features:

  • Represents PLC components and their detailed connections.

  • Contains clearly defined inputs, outputs, and often has references to the PLC program or tags.

  • Allows the designer to map electrical connections directly to logical I/O addresses.

• Common Use Cases:

  • Wiring diagrams for PLC systems.

  • Defining PLC inputs/outputs in control systems.

3. Structure Box

• Purpose: Used to organize and group elements within the schematic for better clarity and logical segmentation.

• Key Features:

  • Acts as a boundary or frame to group related components.

  • Does not represent a device or physical component but rather a logical or functional unit.

  • Can be used to represent functional areas like motor control, power distribution, etc.

• Common Use Cases:

  • Dividing large schematics into logical sections for better readability.

  • Indicating functional areas or sub-circuits.
