REST-API – The easy way to access your machine and process data
Modern ASi-5/ASi-3 Gateways all feature a REST-API interface that provides you with effortless and direct access to machine data and system information – with no impact on ongoing fieldbus communication. The REST API interface is particularly advantageous for data exchange and seamless integration with various software systems, such as ERP, MES, as well as web and cloud applications.
The gateway serves as an ideal edge device for a wide range of IIoT applications: It gathers data and makes it available to higher-level systems for analysis and processing. IIoT applications can use the REST-API for flexible access to the necessary data. This enables the monitoring of processes as well as the recording and distribution of process data within corporate and production systems. Our gateways facilitate easy integration into digital networks and contribute to increased efficiency in modern industrial environments.
What is a REST-API, and how does it work?
A REST-API (Representational State Transfer) is an HTTP-based programming interface designed specifically for data exchange and integration in web applications. Its design is based on a client-server architecture, enabling efficient provision of structured data, particularly utilized in IT environments and web applications.
HTTP methods such as GET, POST, PUT, and DELETE can be used to send targeted requests to the gateway. The gateway processes these requests and returns the responses in an easy-to-read JSON format. The stateless communication of the REST-API ensures that each request is independently handled, allowing fast and flexible data processing.
How to benefit from the REST-API interface
Our modern ASi-5/ASi-3 Gateways offer an extensive range of API endpoints to retrieve specific data and parameters of connected machines and peripherals. With the appropriate API calls, machine and process data can be queried and integrated into IT systems, cloud applications, or web browsers. Utilize these endpoints to execute existing apps and services like condition monitoring and device management.
Direct access to selected ASi-3 and ASi-5 device data: Access is achieved through structured API endpoints, with output in an easy-to-understand JSON format that can be read by both humans and machines.
Simple integration: Thanks to the standardized HTTP request structure, the REST-API can be integrated into existing IT systems, web applications, and cloud environments without significant development effort.
Flexible live data exchange for IT and web applications: Monitor production processes by retrieving input and output data. The data can be used for visualization in web applications or integrated into databases for further analysis.
Remote diagnostics and maintenance: Access vital diagnostic information such as module temperature, voltage, and error lists to detect anomalies early and implement preventive maintenance. You can also view the current status of safety modules or Safe Link nodes to ensure operational safety.
Compliance with cybersecurity standards: Data is encrypted via HTTPS with TLS. Additionally, network ports connected to the REST-API can be blocked by the user locally at the ASi Gateway.
OPC UA
The OPC UA server in our ASi-5/ASi-3 Gateways allows you to access a wide range of machine data. It's easy to retrieve a wealth of information about the machine and the process, from device diagnostics to process data, via the network.
IIoT and Industrie 4.0
To successfully implement IIoT projects, the majority of valuable sensor data must be analyzed within IT. Discover how the high data bandwidth of ASi-5 can help: With the powerful data shuttle, you can easily integrate intelligent sensors such as IO-Link.
IO-Link
Read all about how our TÜV-certified device facilitates "selection of mode of sfae operation selection": A standard HMI allows you to safely select up to 5 different operating modes for a maximum of 6 plant sections – each with unique safety functions.
Cybersecurity
All modern ASi-5/ASi-3 Gateways are updateable and, with signed firmware, can meet future safety requirements long after commissioning. What's more, the communication gap between ASi and TCP/IP enhances cybersecurity. Find out more.
