Secure, zero-code connectivity from legacy Modbus systems to modern IIoT platforms

The FieldServer Modbus IoT Gateway from MSA Safety provides a streamlined, secure way to connect Modbus and OPC UA devices to modern Industrial Internet of Things platforms. Designed for system integrators and industrial environments, the gateway simplifies data access, transformation, and delivery without requiring custom code. 

The FieldServer Modbus IoT Gateway bridges legacy Modbus networks to cloud and on-premise IIoT platforms using widely adopted protocols including MQTT and OPC UA. Built-in support for RESTful APIs and webhooks enables fast integration with dashboards, analytics tools, and enterprise applications.

An intuitive web-based configurator allows users to map Modbus points to cloud destinations in minutes. Features such as live data preview, built-in diagnostics, and template import and export help reduce commissioning time and simplify long-term system management. 

The gateway is engineered for secure industrial deployment, supporting TLS-encrypted communications, role-based access control, and audit logging. It enables secure connectivity to third-party cloud platforms such as AWS, Azure, and Ignition using X.509 certificate-based authentication, with integrated certificate management for credential generation, storage, and expiration notifications. 

Suitable for applications across utilities, general industry, and oil and gas, the FieldServer Modbus IoT Gateway supports RS-485 serial communications, operates across a wide temperature range, and complies with multiple regional approvals. These capabilities help ensure reliable performance in challenging industrial conditions. 

• Zero-code configuration through a visual web interface
• Secure Modbus-to-MQTT and OPC UA connectivity
• Enterprise-grade encryption and certificate-based authentication
• Flexible integration with cloud and on-premise systems
• Designed and tested for industrial deployment

For organizations modernizing legacy equipment or expanding connected operations, the FieldServer Modbus IoT Gateway provides a secure and efficient foundation for IIoT connectivity.
