LMGateway industrial IoT gateway product family

Connect Diverse Field Devices

Bring data from industrial equipment, utility meters and building automation systems into one consistent data layer.

Utility Metering

Electricity, water, heat, cooling and flow meters for AMR and energy projects.

Industrial Automation

PLCs, controllers, drives, machines and production equipment.

Building Automation

HVAC systems, DDC controllers, room devices and BMS networks.

Industrial Interfaces and Flexible Communications

From serial and Ethernet to 4G, Wi-Fi and I/O, choose the hardware configuration that fits the field devices, network environment and installation conditions.

Interface and communication availability varies by product model. Refer to the product specifications for exact configurations.

Deploy the Gateway Runtime on Your Own x86 Platform

Use IoServer when the project requires LMGateway software capabilities on an industrial PC, edge computer or control-room server instead of dedicated gateway hardware.

Flexible x86 Deployment

Run IoServer on an existing industrial PC, edge computer or control-room server.

Windows or Ubuntu

Choose the operating environment that fits the project and existing IT infrastructure.

Licensed Gateway Runtime

Use the same data acquisition, conversion and delivery capabilities with licensed point capacity.

Multi-Protocol Data Acquisition and Conversion

Integrate existing devices without replacing field equipment. Normalize data and expose it through standard northbound interfaces.

Industrial Protocols

Modbus, Siemens S7, EtherNet/IP, IEC 104 and other project protocols.

Building Protocols

BACnet/IP, BACnet MS/TP, KNX and building automation interfaces.

Metering Protocols

M-Bus, DL/T 645, CJ/T 188 and utility meter protocols.

Northbound Interfaces

MQTT, HTTPS, REST API, OPC UA and database integration.

Connect Directly to Your Platform

Use standard interfaces to deliver data to customer-owned cloud services, SCADA, AMR, EMS and enterprise applications.

Open by design

No mandatory manufacturer cloud. No proprietary desktop configuration software required.

Keep Data Safe When Networks Fail

Local buffering and automatic retransmission help protect critical meter and process data during 4G, Ethernet or cloud service interruptions.

Local timestamped data buffering
Store-and-forward delivery
Automatic reconnection and pending-data upload
Historical data, alarms and event records
Optional IoTedgeDB edge time-series storage
Historical data chart

Built-in JavaScript Runtime

Use built-in JavaScript scripting to implement calculations, data transformations, conditional logic and project-specific workflows directly on the gateway—without modifying the standard gateway firmware.

Data Calculation and Conversion

Perform arithmetic calculations, unit conversion, value correction, aggregation, filtering and derived-variable processing using data collected from field devices.

Conditional Logic and Automation

Create conditional rules, event handling, scheduled tasks and automated actions according to device values, communication status or project operating conditions.

JSON Publishing Templates

Define project-specific JSON payload templates for MQTT and HTTP publishing. Organize field names, device identifiers, timestamps, values and metadata to match the data format required by the customer's cloud, IoT or application platform.

Configure and Maintain with a Web Browser

Configure, monitor and maintain the gateway from a local web browser. Selected gateway models also support built-in WebSCADA for real-time visualization and on-site operation.

Device discovery and data-point configuration
Polling interval and destination server settings
Real-time data monitoring, trends and status overview

Reach Remote Gateways and Site Devices Through OpenVPN

Enable the built-in OpenVPN client to create an encrypted connection for remote commissioning, diagnostics and engineering maintenance.

Encrypted Access to Remote Sites

The gateway connects to a customer-owned, project-owned or supported VPN server, providing authorized engineers with a secure path to the gateway and supported devices on the remote site network.

Remote gateway configuration and diagnostics
Secure access to supported Ethernet devices behind the gateway
Remote PLC programming and engineering maintenance
Remote discovery of OPC UA, BACnet and other network services
Avoid exposing field devices directly to the public Internet
