From agreed drawings to a controlled data pack

How PLC Automator turns control drawings into reviewed tag data

From agreed drawings and rules to a controlled, engineer-reviewed data pack.

Define the job

Agree the drawing package, project rules, naming conventions and required export. The scope is fixed before any files are processed.

You choose which drawing types are in scope, the PLC and HMI/SCADA naming rules to apply, and the export format the downstream workflow expects.

Generate the draft

Extract draft PLC tags, descriptions, mappings and permitted alarm data with source references.

For each in-scope page, the system produces draft records linked back to the drawing evidence. It does not invent missing information or complete incomplete sequences.

Review exceptions

Engineers inspect uncertain, incomplete or non-conforming records before approval.

Ambiguous addresses, rule conflicts and missing labels are surfaced as review items. Each exception keeps a reference to the source evidence so engineers can decide quickly.

Export controlled data

Produce the agreed CSV/Excel data pack for the tested downstream workflow.

Only approved records are included. The output is a controlled draft data pack, not a deployed or final engineering deliverable.

Product scope

Tag Data Pack

Candidate PLC tags, descriptions, naming-rule results, source references, exceptions and agreed CSV/Excel export.

Documentation Pack

FAT, SAT, or commissioning documentation generated from source-referenced project data, when validated for the customer workflow.

Code Block Pack

Custom STL/LDR/FBD/other code blocks built on extracted tags — alarms/interlocks/general, engineer-reviewed, never autonomous safety or process-alarm design.

Example output

From a fictional schematic source to a draft record, exception and approved export.
