Modbus IoT Gateway

The FieldServer Modbus IoT Gateway is your streamlined path from Modbus or OPC UA networks to modern IIoT platforms. Whether you're integrating legacy equipment or building new cloud-connected systems, this gateway simplifies data access, transformation, and delivery—with enterprise-grade security and zero-code configuration.

  • Multi-Protocol Cloud Connectivity
  • Interactive Web Configurator
  • Enterprise-Grade Security
  • Can push up to 1,000 Modbus values to the MSA Grid
Highlights

Smart. Secure. Seamless.

Multi-Protocol Cloud Connectivity

Out-of-the-box support for:

  • MQTT – Efficient, lightweight messaging for IoT
  • OPC UA – Secure industrial interoperability
  • RESTful API – Flexible access for apps and dashboards
  • Webhooks – Instant event-driven data delivery

Interactive Web Configurator

Build configurations in minutes
— no coding or scripting:

  • Visual mapping of Modbus points to cloud destinations
  • Live data preview and diagnostics
  • Import, export, and restore for
    template configurations

Enterprise-Grade Security

Designed and tested for secure industrial deployment:

  • Encrypted data channels (TLS)
  • Role-based access control and audit logging
  • Secure connectivity to third-party cloud platforms (e.g., AWS, Azure, Ignition) using X.509 certificate-based authentication
  • Integrated certificate management, including CSR and key pair generation, secure credential storage, and expiration notifications
  • Support for secure MQTT and OPC UA communications
  • OPC UA support for certificate-based authentication with Ignition
  • Supports configuration of a single OPC UA server connection; multiple clients may connect concurrently
