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.
