Introduction

The San Telequip SC10E4I MS Series is a versatile and secure Modbus gateway engineered for modern industrial environments. It serves a strategic role in bridging the gap between legacy serial-based industrial devices and contemporary Ethernet networks. This gateway is designed to solve critical integration challenges, including protocol conversion, data security, and network segmentation, making it an essential component for Industrial Internet of Things (IIoT) applications and factory automation upgrades.

The core function of the SC10E4I MS Series is to provide seamless protocol conversion between Modbus TCP, Modbus RTU, and Modbus ASCII. It enables a wide array of industrial equipment—such as PLCs, HMIs, power meters, and sensors—to communicate effectively across different network types. The gateway features four software-selectable serial ports (RS232/RS485/RS422) that can be individually configured, alongside dual Ethernet ports or optional SFP fiber ports, offering exceptional connectivity and deployment flexibility.

From a technical standpoint, the gateway is a high-performance device capable of managing complex communication loads. It can handle up to 16 simultaneous Modbus TCP masters, with each master making up to 32 simultaneous requests, ensuring scalable and responsive network performance. Crucially, the SC10E4I MS Series embeds robust security features, including PPTP, IPsec, and OpenVPN, to protect data integrity and confidentiality. Its rugged, industrial-grade design is validated by a wide operating temperature range of -40 to 85°C, making it reliable even in the most demanding physical environments. The gateway's value is further defined by a specific set of advanced features designed for flexibility and reliability
