Protoss PW11-H – Wi-Fi Converter RS485 ↔ Modbus TCP
Protoss PW11-H is a communication converter designed to connect RS485 bus devices to an IP network using the Modbus TCP protocol via Wi-Fi connection. In the SHE system, it serves as an essential element for integrating technologies that do not support native Modbus TCP communication.
🔌📶 Protoss PW11-H – RS485 → Modbus TCP (Wi-Fi)
Protoss PW11-H is a converter serving as a communication bridge between devices with RS485 (Modbus RTU) interface and a superior system using Modbus TCP via Wi-Fi connection. It enables integration of inverters, electricity meters, wallboxes, and other third-party technologies into the SHE system, where all control logic is implemented through Quick Apps.
💼 Business presentation
Protoss PW11-H is a key infrastructure element in projects where it is not possible to run an LAN cable and Wi-Fi connection must be used. The converter is widely used in the SHE system and its communication is tested in real installations. It is suitable for installations where flexibility of connection without cabling is emphasized. The converter does not control any technologies by itself, but creates the necessary communication layer without which it would not be possible to integrate technologies into the SHE system. The device includes an external Wi-Fi antenna, which can be routed outside the metal cabinet if installed in a sheet metal enclosure to ensure better signal quality and stability.
🧩 Role in SHE system
Protoss PW11-H is a necessary component of the SHE system in cases where the connected technology does not support Modbus TCP communication and wired LAN connection is not available. The converter is particularly necessary for communication with inverters, wallboxes, EX01 module, and other devices using RS485 bus. Without this converter, it would not be possible to fully integrate and control the mentioned technologies using SHE QA.
