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.

Remonde Retunnel cross-regional networking helps you break geographical barriers and say goodbye to cumbersome VPN setup. It easily solves the challenges of multi-site remote O&M and data collection, making business connections faster, farther and smarter.

Advantages of Retunnel Cross-regional 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

The Retunnel function builds cross-regional network links without public IP addresses, enabling remote communication between devices at two or more locations. For example, the HMI at the master station can remotely access the PLC at the slave station, or PLCs at both master and slave stations can communicate with each other directly.

Remote Data Collection

With Retunnel cross-regional networking, host computers can collect data from multiple on-site devices, multiple on-site devices can transmit data to the host computer, and multiple business systems can simultaneously acquire data from the same on-site device — all without modifying the IP addresses of existing field equipment.

Remote Centralized Monitoring

Through Retunnel cross-regional networking, feeds from cameras, HMIs and industrial PCs across different locations can be unified onto the monitoring center's large screen, meeting the needs of cross-plant centralized production monitoring and work safety scheduling management. It also enables host computers to perform remote configuration, real-time monitoring and parameter setting for PLCs, IPCs, DCS and other industrial control equipment at remote factories, supporting real-time production optimization and fault diagnosis.

Remote Work

Retunnel cross-regional networking connects the local area networks of headquarters, branch offices and off-site employees into a unified internal network. It enables cross-regional mutual access to internal resources such as enterprise systems, business servers and office equipment, allowing employees to work as if they were at headquarters regardless of their physical location.

In summary, Remonde Retunnel cross-regional networking helps you easily address remote O&M and remote collaborative work scenarios across industrial control, OT and IT fields. If you have more networking requirements, welcome to contact us for further discussion!
