Schneider Modicon PLC repair and migration in India
Star Automations is an independent multi-brand repair company, not an OEM service centre. We repair discontinued Schneider Electric Modicon controllers such as the Quantum Unity CPU 140CPU65150 and plan migration to Modicon M580 with program conversion and commissioning support. Every unit gets a bench power-up, backplane check and fault isolation before repair or a migration plan.
