Applies established standards and procedures to configure, test, and support system components, resolve operational issues, and assist with system integrations across field devices, control platforms, and communication infrastructure. Supports system upgrades, maintains accurate documentation, and assists with the administration and maintenance of control system infrastructure, including servers, workstations, network switches, and patching activities. Works closely with operations and maintenance staff to diagnose issues and maintain reliable, secure, and consistent system performance.

EXAMPLES OF PROFESSIONAL WORK:

• Interpret controls narratives to develop and modify PLC logic for process control applications using ladder logic and function block programming.
• Commission, test, and troubleshoot field control panels, PLCs, and remote I/O devices in active plant environments.
• Build and maintain HMI screens for SCADA systems such as Siemens WinCC, GE iFix, or any other applicable platform, based on process requirements.
• Assist other crafts in installing and configuring analog and digital instrumentation (e.g., flow meters, level sensors, pressure transmitters).
• Assist other crafts to perform loop checks, sensor calibrations, and system validation in collaboration with field staff.
• Support wireless (licensed, unlicensed, cellular, and microwave) telemetry systems for remote site monitoring and control.
• Diagnose and correct network communication issues between field devices, PLCs, and SCADA systems.
• Maintain control system servers and associated infrastructure, including monitoring performance, storage capacity, and backup integrity to ensure system availability.
