About 12 Inch Delta HMI

An HMI (Human-Machine Interface) specification is a detailed document or set of guidelines that defines the design, functionality, and performance criteria for the interface through which humans interact with machines, especially in industrial and automation systems.

Key Components of an HMI Specification

Purpose & Scope
- Define the objective of the HMI (e.g., machine control, process monitoring).
- Specify the systems or processes the HMI will interface with.
User Requirements
- Types of users (e.g., operators, maintenance staff, engineers).
- Access levels and roles (e.g., read-only, admin).
Hardware Specifications
- Display size, resolution, and type (e.g., touchscreen, industrial panel).
- Environmental considerations (temperature, IP rating, mounting type).
- Communication interfaces (Ethernet, RS-485, USB, etc.).
Software Requirements
- HMI development platform (e.g., Siemens WinCC, Rockwell FactoryTalk).
- Operating system compatibility.
- Alarm handling, trending, and data logging capabilities.
- Integration with PLCs, SCADA, MES systems.
Functional Requirements
- Navigation structure and screen hierarchy.
- Control functions (start/stop, setpoints, recipes).
- Visualization (process graphics, animations).
- Alarm management (priority, acknowledgment, logging).
User Interface Design
- Layout guidelines and color schemes.
- Font types and sizes.
- Iconography and symbol standards.
- Language support (multi-language support if needed).
Security Requirements
- User authentication and access control.
- Logging of user actions.
Performance Requirements
- Response time for user interactions.
- Screen loading times.
- Uptime requirements.
Testing and Validation
- Pre-commissioning checks.
- FAT (Factory Acceptance Test) and SAT (Site Acceptance Test) criteria.
Documentation
- Operator manuals.
- Maintenance and troubleshooting guides.
- Change log and version control.
