As factories become increasingly geographically dispersed with equipment deployed across the country and even worldwide, how can enterprises realize seamless data interaction and remote O&M between headquarters and factories, as well as among branch plants?

Traditional remote private networks and VPN solutions not only incur high costs, but also feature complex deployment and cumbersome operations, with strict requirements for dedicated network lines and public IP addresses — leaving many enterprises struggling with network connectivity.

Yuanmu ReTunnel’s cross-region networking solution helps you break through geographical barriers and say goodbye to the hassle of setting up VPNs. It makes it easy to tackle challenges such as multi-site remote operations and maintenance and data collection, enabling faster, broader, and smarter business connectivity.

Advantages of ReTunnel for Cross-Region Networking

No Public IP Required

No dedicated lines or public IP addresses are needed. Simply power on the on-site RCH gateway with 4G/Wi-Fi/Ethernet connectivity, and secure communication can be established immediately.

Drag-and-Drop Networking

Cross-regional network links can be easily built by dragging and dropping device assets on the platform. The operation is intuitive and requires no professional networking expertise.

No IP Conflict Issues

Devices at different branch sites can share identical IP addresses. Remote communication is achieved directly without network address translation.

Multiple Communication Modes

Supports flexible communication topologies including one-to-many, many-to-one and many-to-many.

Networking Application Scenarios

Cross-regional Device Communication

By using the ReTunnel feature to establish a network connection between remote locations, devices in two or more locations can communicate remotely without requiring a public IP address. For example, an HMI at the master agent can remotely access a PLC at the Client agent, or a PLC at the master agent can communicate with a PLC at the Client agent.

Remote Data Collection

By using ReTunnel for cross-location networking, applications such as a host computer collecting data from multiple field devices, multiple field devices sending data to a host computer, and multiple business systems simultaneously collecting data from the same field device can be achieved without the need to adjust the IP addresses of the field devices.

Remote Centralized Monitoring

Through ReTunnel’s remote networking solution, cameras, HMIs, and industrial PCs located in various locations can be uniformly connected to the large display screen at the monitoring center, meeting the needs for centralized monitoring of production status across different plant sites and for safety production scheduling and management; It supports remote configuration, online monitoring, and parameter setting of industrial control equipment—such as PLCs, IPCs, and DCS systems—at remote factories via a host computer, enabling real-time optimization of production processes and fault diagnosis.

Remote Work

By using ReTunnel to establish a cross-regional network, the local area networks (LANs) of headquarters, branch offices, and remote employees are interconnected to form a unified internal network. This enables cross-regional access and interconnectivity for internal resources such as internal systems, business servers, and office equipment, so that no matter where employees are located, it is as if they were “working at headquarters.”

Overall, Yuanmou ReTunnel’s remote networking solution can help you easily address scenarios in the fields of industrial control, OT, and IT, as well as remote operations and maintenance and remote collaborative work.
