| 1 | Physical Data Capture | Receives measurements and status signals from sensors, machines, controllers, and operator input devices. | Temperature Pressure Position Digital I/O Touch Input | Raw electrical signals and user commands enter the system. |
| 2 | Signal Conversion | Converts analog signals into digital values and interprets digital signals through suitable interface hardware or industrial I/O modules. | Analog-to-Digital Conversion Digital Inputs Digital Outputs Serial I/O | Machine signals become structured numerical or logical data. |
| 3 | Data Communication | Exchanges data with programmable controllers, distributed I/O, drives, sensors, databases, and supervisory systems. | Ethernet USB RS-232/RS-485 CAN Industrial Protocols | Data is transferred between the panel PC and connected equipment. |
| 4 | Driver and Protocol Handling | Operating-system drivers and communication software organize incoming data according to the connected device and protocol. | Device Drivers Protocol Frames Registers Tags | Raw communications are converted into usable variables and device states. |
| 5 | Edge Computation | The processor performs calculations close to the machine, reducing the need to send every raw value to a remote server. | Scaling Filtering Unit Conversion Boolean Logic Threshold Checks | Cleaned measurements, calculated values, and local decisions are produced. |
| 6 | Real-Time Monitoring | Continuously compares process values with operating limits and updates the human-machine interface. | Setpoints Alarms Status Indicators Trends | Operators receive current process information and abnormal-condition warnings. |
| 7 | Control Instruction | Sends authorized commands or control values to connected equipment according to application logic and operator input. | Start/Stop Speed Reference Mode Selection Setpoint Update | Controllers, actuators, or machines receive actionable instructions. |
| 8 | Local Data Storage | Records selected process values, events, alarms, operator actions, and system diagnostics for analysis or traceability. | Solid-State Storage Event Logs Time Stamps Production Records | Historical information remains available for troubleshooting and reporting. |
| 9 | Visualization and HMI | Presents process data through graphical screens designed for monitoring, configuration, diagnostics, and operator control. | Dashboards Mimic Diagrams Charts Alarm Lists Touchscreen | Complex machine conditions become understandable visual information. |
| 10 | Remote and Higher-Level Integration | Shares selected information with supervisory, manufacturing, maintenance, or cloud-connected systems when network access is available. | OPC UA MQTT SQL Web Services Industrial Ethernet | Production data supports centralized monitoring, analytics, and enterprise reporting. |
| 11 | Fault Handling and Diagnostics | Detects communication failures, abnormal values, application errors, and hardware conditions, then records or displays diagnostic information. | Watchdogs Timeouts Alarm States System Logs | Operators and maintenance personnel can identify problems more quickly. |
| 12 | Industrial Reliability | Supports continuous operation through solid-state storage, fanless cooling in suitable designs, wide-temperature components, sealed front panels, and vibration-resistant construction. | IP-Rated Front Panel Fanless Design Solid-State Storage Watchdog Timer | Stable data processing is maintained in demanding industrial environments. |
