CURRENT WORKFLOW
Writing the code is only one part of the change.
A machine change can touch sequences, interlocks, recipes, HMI screens, and several PLCs at once. Tools can help with individual edits. The hard part is coordinating and validating the complete change across the line.
Translate the request by hand.
A change request describes the intended behavior, not the code. Engineers still have to translate it into sequences, interlocks, recipes, tags, and HMI objects.
Trace the change across every project.
One requirement can affect several PLC and HMI projects. Engineers must find every dependency and keep the changes consistent across the line.
Prove it works before it reaches the machine.
A successful compile only proves the code is valid. Engineers still have to check sequences, operating modes, alarms, edge cases, and recovery behavior before deployment.

HOW IT WORKS WITH LINEXA
Map the full change. Generate every edit. Validate the result.
Turn one request into every change across the line.
Linexa traces the request across the line to find every affected PLC, HMI, sequence, signal, and dependency. One requirement becomes a complete change plan across all relevant projects.
Generate every edit to your coding standard.
Linexa prepares the required PLC and HMI changes using your libraries, naming conventions, block patterns, and engineering rules. The same standard is applied across the full change.
Validate the full change before deployment.
Linexa checks the result against the intended behavior and project dependencies, then tests affected sequences, faults, edge cases, and recovery behavior for unintended effects.
In Practice
The line needs a new product. The change touches more than one machine.
A new package format changes recipes, sequences, HMI screens, setpoints, and handshakes between machines. Linexa breaks the requirement down across every affected PLC and HMI project, prepares the coordinated changes, and validates the complete line behavior before deployment.

Bring the requirement and the relevant PLC and HMI projects. We’ll run the demo on that exact change and the machines it affects.
Frequently asked questions
What do you need to start?
Does Linexa return native PLC and HMI project changes?
How does Linexa validate the change?
Who reviews and deploys the code?
How is Linexa different from PLC code generation tools inside TIA Portal or other vendor IDEs?
How is this different from PLC Version Control?
Does Linexa replace TIA Portal, Studio 5000, CODESYS, or TwinCAT?
