Introduction

This folder contains models and source code used for benchmarking in the paper entitled Hybrid Synchronous-Asynchronous Execution of Reconfigurable PLC Programs in Edge Computing accepted by IEEE TII (doi: 10.1109/TII.2021.3092741). This archive provides all information needed to recreate the performance evaluations presented in the paper including the following:

1. 4DIAC project, including all function blocks type definitions (*.fbt files).
2. Function blocks type definitions modified for TCC just-in-time compiling.
3. Complete FORTE_TCC source code and build scripts (setup_posix.sh).
4. Excerpt of the JIT FB type management in HERE (async. mode only ).
5. Dependencies for compiling FORTE_TCC (Mini-XML and Tiny CC).

System Configuration

The results were obtained on an embedded PLC hardware platform RevPi connect. Details are:

1. Hardware environment : RevPi connect (https://revolution.kunbus.com/revpi-connect/)
2. Engineering environment: 4DIAC 1.31
3. Deployment profiles in 4DIAC: FORTE_LUAJIT +DynamicTypeLoad FORTE_TCC + HOLOBLOC (FB types location: \home\pi\fbtlib) HERE + HOLOBLOC (FB types location: \home\pi\fbtlib) FORTE_precompiled + HOLOBLOC
