   • Support HMI programming, operator-interface modifications, alarm development, and troubleshooting displays.
   • Maintain organized backups, revision histories, and documentation for PLC programs, HMI applications, and machine parameters.
   • Diagnose industrial communication issues involving Ethernet/IP, Profinet, Modbus, and other applicable protocols.
   • Coordinate control-system modifications with production, maintenance, engineering, and safety personnel before implementation.
3. Machine Programming and Automation
   • Troubleshoot and modify machine operating sequences, recipes, settings, and control parameters within approved equipment and process limits.
   • Support programming, integration, and troubleshooting of industrial robots, automated material handling systems, and peripheral equipment.
   • Diagnose communication and coordination issues between molding machines, robots, conveyors, granulators, and auxiliary equipment.
   • Optimize machine cycles, equipment sequencing, alarms, and recovery routines to reduce downtime and improve consistency.
   • Assist with equipment commissioning, control upgrades, retrofits, and integration of new automation technologies.
   • Maintain proper safeguards and safety-system functionality when making programming or control changes.
4. Manufacturing Equipment Reliability and Maintenance
   • Provide advanced technical support for injection molding machines, robots, granulators, conveyors, and other production equipment.
   • Support preventive and predictive maintenance activities involving electrical, electronic, and control-system components.
   • Analyze equipment downtime, recurring faults, alarm histories, and failure trends to identify improvement opportunities.
   • Collaborate with maintenance technicians to resolve complex equipment issues and transfer technical knowledge.
   • Assist with equipment condition assessments, obsolescence reviews, spare-parts planning, and control-system lifecycle improvements.
   • Develop and maintain technical troubleshooting guides, maintenance standards, and equipment documentation.
5. Continuous Improvement and Technical Projects
   • Identify and implement improvements to machine controls, automation, reliability, and production performance.
   • Support root-cause analysis and corrective-action initiatives related to downtime, scrap, cycle time, and equipment reliability.
   • Participate in capital projects, equipment upgrades, new installations, and manufacturing process improvements.
   • Evaluate opportunities to modernize legacy controls and improve equipment diagnostics and maintainability.
   • Collaborate with production, quality, process engineering, and maintenance teams to improve equipment performance and product consistency.
   • Document project scope, programming changes, validation results, and operating instructions.
6. Safety, Compliance, and Documentation
   • Follow established electrical safety, lockout/tagout (LOTO), machine guarding, and hazardous-energy-control requirements.
   • Ensure control-system changes do not bypass or compromise machine safeguards, interlocks, or other required protective functions.
   • Coordinate safety-related control modifications with qualified personnel and the designated safety or engineering authority.
   • Maintain accurate electrical drawings, PLC backups, software revisions, parameter records, and equipment manuals.
   • Follow applicable company procedures and regulatory requirements when troubleshooting, modifying, or servicing equipment.
   • Report equipment hazards, recurring failures, and opportunities to improve maintenance and operational safety.
