IOy Edge I/O Module comes with built-in logic operations and register functions, making it a cost-effective alternative to PLCs.
Case Details
In many production and monitoring scenarios, users only require basic arithmetic functions such as counting, unit conversion, and simple averaging. Using a traditional PLC for these tasks often results in unnecessary cost and complexity.
The IOy Edge I/O Module comes with built-in logic operations and register functions, making it a cost-effective alternative to PLCs. It can directly execute arithmetic logic, while results can be uploaded to the cloud via MQTT, ensuring flexibility and high efficiency.
Applicable Scenarios
- Production Counting: Count material or finished product quantities and calculate unit output.
- Unit Conversion: Convert analog sensor signals (e.g., 4–20 mA) into physical units.
- Simple Averaging: Collect multiple samples of temperature, humidity, etc., and calculate average values for environmental monitoring.
Typical Examples
Production Counting
- Wiring: DI4 connected to material sensor pulses.
- Logic:
- Count accumulated pulses within 8 hours (total production).
- Formula: Hourly Output = Total Count ÷ 8
- Result: Stored in register REG40004
Signal Conversion
- Wiring: AI4 connected to a 4–20 mA flow sensor.
- Logic:
- Formula: Flow = (Current – 4) × (100 ÷ (20 – 4))
- Converts the current signal into actual flow percentage (0–100%).
- Result: Displayed on HMI and uploaded to upper systems.
Temperature Averaging
- Wiring: AI connected to PT100 temperature sensor.
- Logic:
- Collect 10 consecutive temperature samples and calculate the average.
- Formula: Average Temperature = Σ Temperature ÷ 10
- Result: Used for environmental monitoring, reducing fluctuations from single measurements.
Project Value
- PLC Alternative: Meets simple arithmetic requirements at lower cost.
- Quick Deployment: Built-in web interface for fast logic configuration, no extra programming needed.
- Open Connectivity: Results can be uploaded to cloud platforms via MQTT for remote monitoring.
