Discuss this requirementWhat E-Cont provides
Practical support for a defined engineering scope.
Existing industrial systems often need targeted improvement rather than wholesale replacement. E-Cont can assess a defined legacy controls requirement, plan the modification and support implementation through testing and handover.
The scope may include obsolete PLC hardware, a difficult-to-maintain HMI, missing diagnostics or new functionality that must be added to a live machine. Migration promises are kept platform-specific and proportionate to the evidence available from the existing system.
Typical delivery
- 01Legacy PLC and control-system assessment
- 02Siemens migration and upgrade engineering
- 03PLC software modifications and extensions
- 04HMI replacement and diagnostic improvements
- 05Phased cutover and rollback planning
- 06Electrical and software documentation updates
Relevant experience
Evidence behind the service
Experience includes packaging-line modernisation and replacement of legacy hardware on a 25-year-old live facility installation using modern Siemens PLC architecture and a controlled cutover plan.
