Empowering Diverse Industrial Scenarios

Driving Smart Manufacturing Upgrades
Fully supporting bottom-layer control, distributed acquisition and remote monitoring needs.

Production-line automation & motion control

SoftMotion control · EtherCAT bus · CNC

Powered by strong computing and the EtherCAT real-time bus, it precisely achieves millisecond-level motion control of servo axes, robotic arms and CNC equipment.

Distributed unattended stations

4G/5G access · MQTT reporting · offline cache

Suited for remote water, base-station and other outdoor sites. It reports output and status data in real time via wireless networks combined with an MQTT gateway, with offline cache retransmission to withstand network fluctuations.

Legacy devices: one-to-many to the cloud

100M switch ports · PLC cascading · SD-WAN

Using the built-in dual 100M switch ports, legacy PLCs without inter-site networking capability are cascaded onto the network, and cross-region secure tunnels are built for unified cloud management.

Cross-domain centralized O&M & monitoring

Remote debugging · data dashboard · unified management

Unlocks the full-link data from on-site control to the cloud dashboard. Engineers no longer need to travel frequently—they can view global device status and perform inter-site networking remote debugging from the O&M monitoring center.

1/4

Easier on-site debugging

Auto device discovery & quick binding

Devices are auto-recognized when in range, supporting quick binding in under 5 seconds to greatly boost configuration efficiency.

Real-time device OTA

When a device needs an update, use the App to perform real-time device updates and upgrades.

IP configuration

Conveniently configure the device IP address and perform network debugging from your phone, greatly improving on-site O&M and debugging efficiency.

Debug data logging

Features debug data logging with real-time refresh over a time range and frequency value change recording, convenient for debugging and analysis.

Inter-site networking device configuration

Configure the gateway online from your phone—freely edit names and assign devices to organizations, quickly and conveniently.

*Safety: Before debugging a device via Bluetooth,
make sure the DIP switch is in STOP mode.
