KIARA is a Python tool for scanning and enumerating Programmable Logic Controllers (PLCs) using the Modbus protocol. It helps identify PLCs on a network, retrieve basic device information, and list available registers.

• Scan specified IP addresses, IP ranges, or a list from a file.
• Check common Modbus TCP ports (502, 102) for device availability.
• Retrieve PLC information including manufacturer, model, firmware version, and register values.
• Multi-threaded scanning for improved performance.

• Python 3.6 or higher
• pymodbus3 library (pip install pymodbus3)

1. Clone the repository:

   git clone https://github.com/symbolexe/KIARA
   cd KIARA

pip install pymodbus3

python kiara.py <target>

Replace with:

Single IP address: python3 kiara.py 192.168.1.1 or IP range: python KIARA.PY 192.168.1.1-10

File containing IP addresses (one per line): python KIARA.PY targets.txt

View results in the console. PLC information will be displayed for each discovered device.

python kiara.py 192.168.1.1-10

PLC(s) found:
At 192.168.1.1:
  Unit ID: 1
  Manufacturer: Example Inc.
  Model: PLC-123
  Firmware Version: 1.0.0
  Input Registers:
    Register 0: 123
    Register 1: 456
  Holding Registers:
    Register 1000: 789

• Inspired by the need for a simple yet effective PLC scanning tool.
• Thanks to the developers of pymodbus3 for the Modbus library.
