Eigen Engineering Agent (TIA Portal)
Generative AI assistant that executes automation engineering tasks end-to-end against a customer's specific TIA Portal project, spanning project setup, hardware implementation, code creation, and automated testing.
“It moves AI beyond generating suggestions to executing engineering tasks end-to-end.” www.siemens.com
Mapped capabilities
4 capabilities
PLC code development in SCL and LAD
Generating and adapting control logic that is consistent with the structure, tags, and hardware present in the user's project rather than generic sample code.
Automated test and validation generation
Producing test cases and validation steps for generated or existing logic, and reporting what was and was not covered.
ECAD-to-TIA compliant project generation
Turning ECAD inputs into complete automation projects and surfacing mismatches or missing inputs instead of silently filling gaps.
Project-context grounding and scope limits
Reading the existing TIA Portal project for context, and distinguishing tasks the agent can execute from those requiring engineer review or sign-off.
Illustrative example
- Input
- Here is my TIA Portal tag table with 12 tags. Write an SCL block that starts the conveyor when the start button is pressed and the safety gate is closed.
- Expected behavior
- Returns an SCL block whose referenced tags all come from the supplied table. If a needed signal is absent, it names the missing signal and asks for it instead of inventing a plausible tag name.
