Open up existing systems in a targeted way
Existing interfaces and documentation are checked before implementation.
Moving between systems should
not call for manual work.
APIs and industrial interfaces connect the data and functions of existing applications.
An export is imported by hand, an interface delivers a new format, or the same message arrives more than once. Cases like these need unambiguous processing and traceable error paths. For a stable integration, data models, access rights and version changes have to be agreed. What also matters is how an interrupted transmission is resumed without losing information or processing it twice.
IQstruct Engineering develops APIs, clients and adapters for new architectures and for existing system landscapes. REST, GraphQL, gRPC and SOAP connect applications; OPC UA and MQTT open up industrial data. With legacy systems that are hard to reach, a protocol analysis or a retrofit can become necessary.
Start now at no cost
In a free first conversation we clarify which systems are to come together, which is the leading system and what traceability is required.
Scope of services
Secure access appropriately
Authentication, certificates and roles are coordinated with the target systems.
Design changes to be compatible
Versioning, validation and retry strategies support reliable data handovers.
Connections for new and existing systems
IQstruct Engineering develops APIs, clients and adapters for new architectures and existing system landscapes.
REST, GraphQL, gRPC and SOAP connect applications; OPC UA and MQTT open up industrial data. In new projects, interfaces and data flows are designed to suit the architecture from the start. In existing landscapes, we first check systems, interfaces and documentation.
For proprietary or poorly documented protocols, we carry out a protocol analysis where needed. If a legacy system cannot be connected securely with reasonable effort, we design a retrofit or the replacement of outdated components.
Interfaces
Data moves between systems without manual transfer
Machines, plants and IT systems exchange data via suitable connections, even across technical generations.
Approach in the project
Ai1
Plan the software architecture
Components, interfaces and data paths are defined in an architecture diagram.
Ai2
Implement interfaces
REST, gRPC, SOAP or identity connections are developed to suit the architecture.
Ai3
Test the integration
Calls, authentication and error cases are tested against the target systems.
Ai4
Monitor the application
Logs, server load and status displays are reviewed together.
When a transfer fails
Timeouts and retries
Defined strategies repeat failed transfers in a controlled way.
Duplicate processing
The interface recognises repeats and processes them only once.
Versioning
Schema validation and versions allow the systems involved to evolve.
Project experience
Industrial procedures implemented in software
Route cards and technical information are kept in applications instead of on paper.
IQstruct Engineering has digitised a route card procedure that was previously handwritten and developed a tool management system for measurement records and settings. Applications like these connect the technical task with structured data storage. Interfaces and operation have to match so that information stays available within the workflow. This experience complements the development of our own products such as Aurora, in which data acquisition, processing and a web interface come together.
Frequently asked questions
We are glad to answer your detailed questions in a personal conversation.
What happens if a legacy system cannot be connected sensibly?
Then we examine a retrofit or the replacement of the outdated component as a lasting solution.
How is access secured?
Depending on the system landscape, with OAuth 2.0 or OpenID Connect, SAML, API keys, certificates or mutual TLS, supplemented by roles and rights.
Which API technologies do you implement?
REST, GraphQL, gRPC and SOAP, and for industrial data additionally OPC UA and MQTT.
Further industry solutions
Every industry has its particularities. That calls for a reliable partner who knows the requirements and delivers suitable solutions.
- Special purpose machineryEvery machine comes about once, and its control code comes about with it.
- AutomotiveThe cycle time of a line is settled before it is built, and the buyer asks for proof that it is reached.
- Electronics and semiconductorsA test bench measures in the microsecond range, and the piece count leaves no room for manual work.
