ADLINK GW-01 Industrial IoT Gateway Configuration and Debugging Guide

Check MQTT keep alive settings (recommended for 60s).

If using certificate authentication, confirm that the certificate has not expired and the format is correct.

When enabling TLS, ensure gateway time synchronization (NTP), otherwise certificate verification will fail.

7.4 Data value jumps or anomalies

Check whether the byte order (big end/small end) of PLC data type matches, which can be adjusted in the label properties.

Confirm if the register address offset is correct (such as Modbus addresses starting from 0 or 1).

Enable data dead zone filtering and ignore minor changes (such as<1% not updating).

7.5 Gateway overheating or frequent restarts

Check if the working environment temperature exceeds 70 ° C, ensure good ventilation, and avoid approaching heating equipment.

Verify if the power supply voltage is stable, as transient fluctuations may cause a reset.

Check the system load. If the CPU exceeds 80% for a long time, consider optimizing the collection strategy or upgrading to a 1GB memory model.

Expanding Applications and Secondary Development

GW-01 is based on Linux system, and advanced users can log in via SSH (requires activation) for customized development:

Install custom Python/C applications and collect data through shared memory or local sockets.

Add non-standard protocol drivers (requires iM Connect SDK or self-developed).

Integrate third-party edge computing frameworks (such as Node RED, AWS Greengrass).

But the official recommendation still focuses on web configuration to maintain system stability and technical support consistency.

Maintenance cycle and spare parts recommendations

Regularly (quarterly) check whether the serial port and network cable connectors are oxidized, and replace them if necessary.

Backup the configuration file every six months and store it on the on-site maintenance computer.

Reserve a gateway of the same model as a spare part, which can be quickly replaced in case of hardware failure of the main device, and can be restored by importing the backup configuration.

Follow the ADLINK official website for updates on iM Connect software to obtain new protocol drivers and security patches.
