## What it is
OpenPLC Runtime version 3 is an open-source Programmable Logic Controller (PLC) runtime that executes ladder logic and other IEC 61131-3 programs on low-cost hardware like Raspberry Pi or standard Linux/Windows machines. It is widely used for industrial automation and as a full-source-code platform for industrial cyber security research, but has reached end of life in favor of OpenPLC Runtime v4.

## Use cases
- run a software PLC on a Raspberry Pi for home or lab automation
- set up an open-source PLC for industrial control experiments
- build an ICS/SCADA cyber security research testbed with full source access
- simulate a programmable logic controller in Docker for testing
- control industrial hardware over Modbus or EtherCAT with open-source software

## When to choose
- you need a fully open-source PLC runtime for research or education
- you want a low-cost automation controller on a Raspberry Pi or Linux box
- you need complete source code access for industrial security studies

## When to avoid
- you are starting a new project - use OpenPLC Runtime v4 instead, as v3 is end of life
- you need certified, safety-rated industrial control hardware
- you require vendor support or long-term maintenance guarantees
