PanelServer PAS600 Modbus Monitor

A C++ application to monitor Schneider Electric iA9MEM15 (Single Phase) and iPM2xxx (3-Phase) energy meters via Modbus TCP through a PAS600 Panel Server outside. It collects electrical measurements, stores them in local SQLite databases, and tracks historical energy trends.

Features

• Multi-Device Support: Monitor multiple devices (iA9MEM15 & iPM2xxx) in a single loop.
• Dual Database Storage:
  • iA9MEM15.db: Stores single-phase readings.
  • iPM2xxx.db: Stores 3-phase readings.
• Historical Tracking: Tracks Total Energy (Delivered + Received) history:
  • Last 1 Minute
  • Last 5 Minutes
  • Last 30 Minutes
  • Last 1 Hour
  • Last 2 Hours
• Robustness:
  • Auto-reconnection logic.
  • Safe handling of NaN / invalid sensor values.
  • 60-second polling loop.
• Configurable: Uses a simple .env file (or environment variables) for network and device settings.

Prerequisites

• C++ Compiler: Supporting C++17 or later.
• CMake: Version 3.16+.
• SQLite3: Source code is bundled/downloaded automatically by the build script (no manual install required).

Configuration

Create/Export environment variables (or use a .env file loader if implemented):

export MODBUS_IP=192.168.100.100   # IP Address of the Modbus Server/Gateway
export MODBUS_PORT=502            # Modbus TCP Port (usually 502)
export DEVICE_IDS=100,101,102     # Comma-separated list of Unit IDs to poll

Build and Run

The project includes a helper script to build and execute the application.

1. Make the script executable (first time only):

   chmod +x build.sh

2. Build and Run:

   ./build.sh

Database Schema

1. iA9MEM15.db (Table: readings)

• Metrics: Voltage (A-N), Current (A), Power (A, Total), PF, Internal Temp.
• History: total_energy + total_energy_last_XM.

2. iPM2xxx.db (Table: readings_pm2xxx)

• Metrics:
  • Voltage: Phase A, B, C, Avg (L-N).
  • Current: Phase A, B, C, Avg.
  • Power: Active, Reactive, Apparent (Total).
  • Basics: PF, Frequency.
• History: total_energy + total_energy_last_XM.

Data retention policy: Records older than 2 days are automatically deleted.
