I recently embarked on a project to integrate my PLC (Programmable Logic Controller) into my smart home ecosystem using Modbus. The setup involved configuring the PLC to communicate with my smart home gateway via Modbus, which turned out to be quite straightforward. By assigning specific Modbus addresses to different functions, I was able to automate various processes seamlessly. However, I encountered a challenge when searching for a user-friendly app that could simplify the configuration and monitoring of these Modbus connections. After some research and experimentation, I discovered that while dedicated apps for this purpose were scarce, creating custom scripts using Python and Node-RED proved to be a viable workaround. This approach not only allowed me to tailor the system to my needs but also deepened my understanding of Modbus communication protocols. If anyone has insights or alternative solutions for integrating PLCs more efficiently, I’d love to hear your thoughts!
