EPLAN documentation
EPLAN and electrical documentation support for industrial automation.
Support for retrofit documentation, cabinet documentation, machine handover and maintainable electrical project records.
Short positioning
This service supports U.S. industrial teams that need clearer electrical documentation for automation systems, control cabinets, retrofit work, machine handover or maintenance troubleshooting. The focus is not documentation for its own sake. The goal is documentation that helps technicians, engineers and commissioning teams understand the real system.

Typical problems we solve
Industrial automation work often becomes harder because the electrical documentation is incomplete, outdated or not aligned with the current machine state. This is especially common after retrofit, relocation, commissioning changes or OEM handover.
- EPLAN projects need review, cleanup or updates
- Cabinet documentation does not match the field state
- Retrofit changes are not documented clearly
- Maintenance teams need better handover material
- PLC migration requires I/O and electrical context
- Wiring, terminal, device, sensor and actuator references are unclear
Systems and platforms covered
Support can include EPLAN documentation, electrical cabinet records, I/O mapping support, as-built updates, retrofit documentation and documentation that connects electrical changes with PLC and commissioning work. Typical related systems include Siemens, CODESYS-based PLCs, WAGO I/O, Profinet devices, Modbus TCP devices, HMI stations and industrial network components.
The work can support both a new documentation package and a practical update to existing drawings, markups, photos or OEM documents.
How support works
The first step is to review the current documentation, machine state, known changes and the purpose of the update. Documentation work is most valuable when it directly supports maintenance, commissioning, migration or fault diagnosis.
A good documentation review compares what the drawing says with what the cabinet, I/O list, PLC project and machine actually show. When a retrofit is planned, documentation should be updated before commissioning decisions are made. When a machine has already changed, documentation should capture the as-built state and the remaining unknowns.
Remote vs onsite support
Remote support can work well when current EPLAN files, PDFs, photos, redlines, I/O lists and PLC project information are available. Remote review can identify missing pages, unclear device references, inconsistent I/O naming and documentation gaps before onsite verification.
Onsite support is useful when the cabinet state must be checked directly, when labels or wiring need visual verification, or when commissioning changes must be documented during machine work. Onsite work should be prepared with the latest available drawings and a clear documentation goal.
Deliverables / what the customer gets
- EPLAN review and update notes
- As-built documentation support
- I/O, terminal, device and cabinet documentation observations
- Retrofit documentation package support
- Maintenance handover notes for U.S. teams
Good fit / not a good fit
Good fit: retrofit documentation, machine handover, cabinet documentation, I/O mapping, EPLAN review, migration support and maintenance-oriented as-built updates.
Not a good fit: purely decorative drafting, undocumented systems where no verification path is possible, or legal certification of electrical drawings without the required responsible review.
Related technologies
Related technologies include EPLAN, electrical drawings, I/O lists, terminal diagrams, control cabinet documentation, Siemens TIA Portal, CODESYS, WAGO, Profinet, Modbus TCP and commissioning checklists. Documentation often supports PLC migration and retrofit or PLC troubleshooting.
Related case studies or examples
A typical example is a machine where the PLC project and the electrical drawings no longer match after years of service changes. Another example is a retrofit where I/O mapping must be clarified before a controller migration can be planned. The migration case study shows why documentation and behavior review belong together.
FAQ
Is EPLAN the main service?
EPLAN is part of the service portfolio, especially when documentation supports retrofit, commissioning or maintainability.
Can documentation work be remote?
Often yes, if current files, photos, markups and technical context are available.
What should be sent first?
Send the current drawings or PDFs, machine type, known changes, photos if available, PLC platform and the reason documentation needs to be updated.
Next step
Send the documentation context, current file format and project goal. If the drawings are incomplete, explain what is known and what must be verified.
