Rapid Control System Reverse Engineering & Rebuilds

Exka uses proprietary offline automation tools to reverse engineer and rebuild control systems across PLC and SCADA brands, reducing engineering time and cost. We reconstruct engineering datasets and missing control documentation, and deliver runnable, rewritten PLC and SCADA applications for client review and testing.

Rapid delivery

How a rebuild runs

From the existing system to a working rebuild

Service details
  1. 1

    Analysis & reverse engineering

    A traceable baseline of the existing system, documentation gaps and open questions.

    You review and confirm

  2. 2

    Engineering data & documentation

    A structured engineering dataset, control descriptions and supporting lists and drawings.

  3. 3

    PLC & SCADA rewrite

    Runnable new PLC and SCADA applications.

  4. 4

    Client trial

    Hands-on experience of the new system before any site work.

    You return an issue list

  5. 5

    Fixes, improvements & virtual commissioning

    An updated system, test records, and a close-out record for every issue.

    You accept the virtual FAT

  6. 6

    Site implementation & handover

    A maintainable system with updated documentation and engineering data.

Runnable systems

Operate the rebuild before site work

Clients receive a runnable PLC and SCADA rebuild to operate and inspect before any site work, and confirm control behaviour, screens, alarms and diagnostics for themselves.

  • Normal start and stop
  • Auto / manual changeover
  • Sequences
  • Interlocks
  • Alarm acknowledge and reset
  • Equipment faults
  • Communication failures
  • Recovery to normal operation
  • Event recording
Digitalisation

A data foundation for digitalisation

Reliable digitalisation starts with well-defined plant data. Exka rebuilds equipment structures, tag definitions, alarms, interlocks and event-recording logic alongside the control system, giving reporting, asset management, MES and analytics platforms a consistent and traceable source of operational information.

  • One asset hierarchy, naming convention and equipment model. Equipment and data can be related across systems.
  • A data dictionary and explicit state definitions. Fewer misinterpretations and repeated mappings.
  • Rules for start, end, cancel, reset and reason codes. Events and statistics can be traced.

Discuss your existing system

Tell us which PLC and SCADA you run, roughly how large the system is and what documentation exists. A first enquiry does not need project files.
