ADLINK GW-01 Industrial IoT Gateway Configuration and Debugging Guide

ADLINK GW-01 Industrial IoT Gateway Protocol Configuration and Deployment Guide

ADLINK GW-01 is a compact IIoT gateway designed specifically for industrial field data acquisition and protocol conversion, equipped with TI Sitara AM3352 ARM Cortex-A8 1GHz processor, built-in 512MB SDRAM and 4GB eMMC storage, supporting 2 10/100M Ethernet and 2 serial ports (RS-232 and RS-422/485), and equipped with 19.2V to 28.8V isolated power supply and isolated communication port. Its core value lies in the pre installed iM Connect protocol conversion software, which can natively support over 300 PLC protocols (covering mainstream brands such as OMRON, Mitsubishi, Siemens, etc.) when running, and seamlessly integrate with mainstream cloud platforms through OPC UA, MQTT, and RESTful APIs. Based on product technical specifications, this article systematically outlines hardware installation points, protocol configuration methods, cloud docking processes, serial port and network debugging techniques, as well as common on-site troubleshooting strategies, to help automation engineers quickly complete gateway deployment and system integration.

Product positioning and applicable scenarios

GW-01 is positioned to address the pain points of heterogeneous device interconnection in industrial sites. In traditional production lines, different brands of PLCs use their own proprietary protocols, resulting in the inability to unify data aggregation. As a protocol conversion middleware, GW-01 can connect multiple PLCs simultaneously (via serial port or Ethernet), standardize data into MQTT/OPC UA format, and upload it to the cloud or SCADA system. Typical applications include:

Old equipment data collection and remote monitoring (replacing discontinued data collection modules)

Unified data interface for multi brand PLC production lines

Data source of edge computing and predictive maintenance system

Instrument data integration of energy management system

Its metal casing, DIN rail installation, PCB three proof paint protection, and wide temperature operation (-20 ° C to 70 ° C) ensure stable operation in harsh industrial environments.

2.3 Installation precautions

Power wiring: Please refer to silk screen printing for terminal definition and pay attention to polarity (V+, V -, FG). Isolating the power supply effectively prevents ground loop interference, and it is recommended to use shielded twisted pair cables.

Serial port wiring:

The RS-232 port (COM1) is a standard 9-wire system (TXD, RXD, GND, etc.) used to connect older PLCs or HMIs.

The RS-422/485 port (COM2) is a differential signal (A, B, GND) that can be connected to a multi station RS-485 network. Pay attention to terminal resistance matching (usually 120 Ω).

Network ports: Two Ethernet ports can be configured as different subnets or in one up one down (WAN/LAN) mode to isolate the on-site control network from the office network.

Grounding: The casing needs to be reliably grounded (FG terminal) to improve anti-interference ability.

Basic operation of iM Connect software platform

GW-01 comes pre installed with Linux kernel (3.14) and iM Connect runtime. Users can configure the gateway IP address through a web browser (supporting Chrome/Firefox) without installing dedicated PC software.

3.1 Initial Startup and Network Configuration

Turn on the power and wait for about 60 seconds for the system to complete startup.

Obtain IP through DHCP (enabled by default), or set a static IP in the serial console (logged in via RS-232).

Enter http://<Gateway IP>in the browser, and the default username/password is admin/admin (forcibly changed upon first login).

The main interface displays the system status (CPU load, memory, temperature, network interface).

3.2 Protocol Driver Management

IM Connect has a built-in protocol library that covers:

Japanese: OMRON (Host Link, FINS), Mitsubishi (FX, Q-series MELSEC), Panasonic, Yaskawa

European and American series: Siemens (S7-200/300/400/1200/1500 via TCP/IP or MPI/PPI）、Allen-Bradley（DF1、EtherNet/IP）、Modbus（RTU/ASCII/TCP）、Profibus DP（ Additional hardware and software support are required

Others: Schneider, GE, Honeywell, etc

When adding a new device, select the corresponding protocol driver, configure communication parameters (serial port baud rate, data bits, stop bits, parity; Ethernet IP/port, station number, etc.), and the system will automatically generate a data label table.

3.3 Data Point Configuration

Users can manually create variables (register address mapping) or automatically enumerate PLC memory areas through the "scanning device" function (supported by some protocols). The supported data types include Bool, Int16, UInt16, ∝, Float, String, etc. Each data point can be set with a collection period (such as 100ms~60s) and a change threshold (dead zone) to reduce network load.
