As a leading China Gateway Modbus TCP RTU Manufacturer, we recognize that the transition from legacy serial communication to Ethernet-based industrial IoT (IIoT) is the cornerstone of modern automation. Our technical roadmap focuses on bridging the gap between field-level RTU devices and enterprise-level management systems via robust Modbus TCP gateways.
Optimizing packet handling to ensure real-time data acquisition in complex Modbus RTU networks, reducing jitter in high-speed industrial environments.
Implementing protocol filtering and secure boot features in our next-generation gateways to protect critical infrastructure from network vulnerabilities.
Moving beyond simple protocol conversion to include edge data processing, allowing for local alarming and data normalization before reaching the cloud.
Traditional Modbus RTU remains a workhorse due to its simplicity and RS485 reliability. However, the rise of Industry 4.0 demands the bandwidth and interoperability of Modbus TCP. Our factories specialize in hybrid solutions—converting 4-20mA and HART signals directly into Modbus TCP streams, enabling legacy sensors to participate in AI-driven predictive maintenance.
Information Gain: Unlike standard converters, our SM-Series gateways feature dual-stack communication, allowing simultaneous polling of HART variables and Modbus registers without signal interference.
Jiaxing Songmao Electronics Co., Ltd. was established in 2007. It has always been driven by technological innovation, deeply engaged in the field of industrial automation, and gradually developed into a high-tech enterprise integrating R&D, production and sales.
The company focuses on the independent research and development of core technologies such as HART protocol communication products and data collectors. Through continuous technological breakthroughs and market expansion, it has established a leading position in the industry.
Remote monitoring of flowmeters and pressure transmitters using Modbus RTU to TCP gateways for long-distance data transmission in hazardous areas.
Integrating diverse sensor networks (PH, turbidity, flow) into a centralized SCADA system via multi-channel HART data collectors.
Efficient data acquisition for municipal heating networks, ensuring heat balance and energy conservation through precise Modbus protocol conversion.
Our solutions are also widely used in Environmental Protection (emissions monitoring) and Natural Gas distribution. Each application demands high reliability and "always-on" connectivity, which is why our China-based manufacturing facility adheres to strict ISO and CE standards.
Choosing a Gateway Modbus TCP RTU Factory in China offers more than just cost advantages; it provides a resilient ecosystem of components and engineering talent. Our Jiaxing-based facility leverages local supply chain clusters to ensure rapid prototyping and high-volume production without compromising on quality.
Modbus RTU is a serial protocol (RS485/RS232) using binary encoding, while Modbus TCP is encapsulated in Ethernet packets. Our gateways bridge these two, allowing older RS485 devices to communicate over modern Ethernet networks.
Yes, we are specialists in HART communication. Our SM100-series converters can extract digital HART data from a 4-20mA loop and map it directly to Modbus registers for easy PLC access.
We offer collectors ranging from 8-channel to 32-channel configurations, such as the SM100-M-32, designed for high-density sensor environments.
Absolutely. As a direct manufacturer, we offer custom firmware, private labeling, and hardware modifications to meet specific regional compliance or technical requirements.
