This drawback can be easily avoided, if you use ready-made module with high-level programming language.
Check for example IPJV-ES module - it is based on the IP2022 and have embedded Java virtual machine. All necessary external interfaces available, you simply need to write your Java program and upload it to the build-in FTP - and project like this is finished.
