In the energy sector, SCADA, EMS, and "monitoring platform" are often confused. Wrong expectations lead to project failure. This guide clarifies the layers and explains Ranaliz's position.

## Short Answer

**SCADA** is the field automation and control layer (PLC, RTU, park controller). **EMS** (Energy Management System) focuses on consumption optimization and demand management. **Ranaliz** reads SCADA/RTU data and delivers **monitoring, analytics, alarms, tasks, and reporting** — it is neither full SCADA nor full EMS; it is an **APM/monitoring layer**.

## Layer Model

```
┌─────────────────────────────────────────┐
│  Ranaliz (Monitoring + Analytics + O&M) │  ← This layer
├─────────────────────────────────────────┤
│  EMS (Consumption optimization, demand) │
├─────────────────────────────────────────┤
│  SCADA (Control, automation, PLC/RTU)   │
├─────────────────────────────────────────┤
│  Field Devices (inverter, turbine)      │
└─────────────────────────────────────────┘
```

## What Is SCADA?

**Supervisory Control and Data Acquisition:**

- Real-time control and automation
- PLC, RTU, park-controller programming
- Breaker, reactor, compensation control
- Industrial protocols (Modbus, IEC-104, DNP3)
- Grid connection point control

**Example SCADA vendors:** Siemens WinCC, Schneider SCADA, Meteocontrol (grid control), turbine manufacturer SCADA.

## What Is EMS?

**Energy Management System:**

- Consumption optimization and demand management
- Load shifting
- BESS charge/discharge strategy
- Optimization based on tariff and market prices
- Building automation integration

**Example EMS:** Schneider EcoStruxure, ABB Ability, custom optimization software.

## What Is Ranaliz?

Ranaliz is an **energy monitoring and operations platform**:

| Capability | Ranaliz | SCADA | EMS |
|------------|---------|-------|-----|
| Live monitoring | ✓ | ✓ | ✓ |
| Alarm management | ✓ | ✓ | Partial |
| Task / O&M | ✓ | Partial | ✗ |
| PR / loss analysis | ✓ | Partial | ✗ |
| AI / forecast | ✓ | ✗ | Partial |
| PTF visibility | ✓ | ✗ | Partial |
| PLC control | ✗ | ✓ | ✗ |
| Demand optimization | ✗ | Partial | ✓ |
| Grid control | ✗ | ✓ | ✗ |

## How Ranaliz Uses SCADA Data

Ranaliz reads data from field devices and SCADA/RTU:

- **Modbus TCP/RTU:** Inverters, meters, sensors
- **IEC-104:** RTU, transformer, grid point
- **MQTT:** IoT sensors

It converts this data into meaningful KPIs, alarms, charts, and reports. It **does not send control commands** (setpoints, breaker open/close, etc.).

## Typical Project Scenarios

### Scenario 1: PV + Monitoring (no SCADA)

Ranaliz reads directly from inverters via Modbus. Fully sufficient.

### Scenario 2: PV + RTU/SCADA + Ranaliz

Park controller or RTU exists on site. Ranaliz reads via IEC-104/Modbus; SCADA control layer remains separate.

### Scenario 3: Industrial + EMS + Ranaliz

EMS handles demand optimization; Ranaliz provides consumption/production visibility and alarms. Integration possible via API.

## Common Mistakes

1. **"Is Ranaliz SCADA?"** — No; monitoring and operations layer
2. **"Does Ranaliz control compensation?"** — No; it monitors cos φ, does not control
3. **"Does Ranaliz do grid control?"** — No; vendors like Meteocontrol do grid control
4. **"Is a vendor portal SCADA?"** — No; brand-focused monitoring panel

## Ranaliz vs SCADA Vendor

| Topic | Ranaliz | Meteocontrol (SCADA) |
|-------|---------|----------------------|
| Grid control | ✗ | ✓ |
| Portfolio O&M | ✓ | ✓ |
| Turkey PTF | ✓ | Partial |
| Alarm → task | ✓ | Partial |
| Deployment complexity | Medium | High |

## Conclusion

SCADA controls, EMS optimizes, Ranaliz **makes visible and manages operations**. Correct layer expectations are key to project success.
