Machine Software Architect - End-of-Line (EOL) Cab Tester for Motor Graders

Caterpillar Inc.

EOL Cab tester is an application that helps the factory to verify the correctness of the connected machine harness. This application works based on the proprietary EOL protocol over J1939. Each IO connected to the machine controller is pinged by the EOL Tester (stand alone setup) by setting the IO to one of its several possible states (On/Off for outputs, various input states for inputs. Crucial component of this project is to port the existing EOL application to a new platform (B5:M5). This software will be used in EOL testing for Motor Grader (MG) machines. 

Key Responsibilities & Achievements:

  • Performed requirement analysis & laid out the base software architecture.
  • Leveraged & reused content from existing EOL applications, there by reducing the development time & effort.
  • Provided guidance to the developer on porting the software to B5:M5
  • Reviewed the activities & provided timely feedback.

Machine Software Developer - Jumbo Drills Motor Control Center

Caterpillar Inc.

Motor control center is a control component in the Jumbo Drills machine. This component is responsible for remotely controlling of various electrical components like Pump Sump, Air compressor etc. The control system works on Modbus. The control system consists of a CAT ECM (Modbus client), Eaton Gateway (Modbus server) & Eaton control devices (control the electrical components in the system). CAT ECM commands the Gateway to control the electrical components.
The scope of this project is to deliver a Modbus TCP library package that enables the application (CAT ECM) to communicate with the gateway.

Key Responsibilities:

  • Responsible for design, development, validation of the MBUS TCP library package customized to work with Motor control center gateways.
  • Performed a deep dive discussion with the customer to derive the critical software requirements.
  • Understood the existing application's software architecture & proposed a library design that will meet the existing standards.
  • Designed & Implemented a library that will enable the application to configure the gateway with minimal code changes (like adding a few macros & commands for the gateway)
  • Reverse engineered Eaton's gateway behavior in some scenarios from Raspberry Pi logs provided by the customer.
  • Thorough understanding of requirements & solid design enabled the delivery of the library with minimal test–fix iterations.
