FACTORY I/O

FACTORY I/O is a software simulation tool that allows users to create and simulate industrial automation systems in a virtual environment. It provides a realistic and interactive platform for training, testing, and troubleshooting automation processes without the need for physical equipment. Users can design their own control systems, program PLCs, and observe the behavior of machines and processes in real-time.

FACTORY I/O publishes 3 APIs on the APIs.io network: Tag Values API, Tag Values by Name API, and Tags API. Tagged areas include Industrial Automation, Simulations, and Software Simulation.

The FACTORY I/O catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

FACTORY I/O’s developer surface includes documentation, engineering blog, and 4 more developer resources.
