  • Operator interface re-engineering

    Client : Leading Industrial Control OEM


    Client is a leading provider of I/O modules, operator interfaces for industrial controls


    • Client had been providing I/O modules, operator interfaces for industrial controls. Client wanted to replace its existing hardware board due to obsolescence and enhancement issues of its components/parts. In addition to this, Client wanted to migrate its application (from assembly language to C-programming), porting over new board and testing.

    • Client selected Softdel as engineering partner considering its capabilities & experience in executing projects around embedded/platform development, software re-engineering & testing.

    • To re-engineer the hardware and firmware of operator interface products due to obsolescence & enhancement issues of its parts.


    Requirements Engineering

    • Product design review

    • Identification of key areas to address obsolescence and enhancement issues

    Hardware, Firmware Re-engineering

    • Replaced the obsolete ASIC with an advanced ARM based microcontroller

    • Migration of existing firmware from assembly to C code

    Interface development

    • Modbus, DF1 and DH485 (proprietary) interface development

    Value Benefits

    • Increased the shelf-life of the product

    • Future-Proof design to accommodate futuristic requirements

    • Common platform to accommodate different legacy products hence cost reduction

    • Improved maintainability by optimized design and proper documentation
