Why Siemens 6SN1118-0N and 6SN1118-1N OEM modules remain essential
The 6SN1118 OEM modules, including 0NJ, 0NK, 0NP and 0NH variants, are still widely used across European industrial plants due to their stability and technical compatibility.
They often contain unique firmware developed by Siemens for specific machine builders and cannot be replaced with standard units without modifying the system logic.
⚠️ However, repairing or regenerating these modules requires Siemens-certified equipment and qualified technicians.
Unprofessional interventions may corrupt firmware data or render the module unusable.
E-Repair, Siemens Approved Partner – Industry Services, is the only European laboratory authorised to carry out certified regeneration of SIMODRIVE 611 OEM modules, including 0NH versions.
Using original SINUMERIK test benches and dedicated firmware diagnostic procedures, E-Repair guarantees like-new performance and preservation of OEM compatibility.
Certified E-Repair regeneration is the safest solution to keep discontinued Siemens OEM modules operational.
