DCS; Distributed Control System & Instrumentation Engineer - ABB

Overview

A DCS Instrumentation Engineer with a strong background in ABB DCS and SCADA systems for sewage treatment plant (STP) operations. The role involves end-to-end responsibility for process control instrumentation asset reliability and industrial communications, focusing on maintaining the health of Profibus DP, PA networks.

• End-to-end responsibility for process control instrumentation asset reliability and industrial communications.
• Administer, operate, and optimize ABB DCS, including control strategies, graphics, alarms, trends, historian tags, and backup/restore.
• Maintain and enhance SCADA interfaces, dashboards, and reporting for O&M and compliance KPIs.
• Develop, test, and implement logic modifications, loop tuning, interlocks, per missives, and sequences under strict MOC procedures.
• Manage alarm rationalization and limit settings to reduce nuisance alarms and improve operator effectiveness.
• Coordinate factory and site acceptance testing (FAT/SAT) for control system changes and expansions.
• Own the lifecycle of field instruments—selection, installation, calibration, loop checks, diagnostics, and replacement.
• Ensure Profibus DP/PA network reliability—topology design, segment diagnostics, termination, shielding, earthing, redundancy, spur lengths, baud rates, device addressing, and GSD management.
• Use diagnostic tools (e.g., bus analyzers) to identify noise, reflections, voltage drops, telegram errors, and intermittent faults.
• Integrate field devices via Profibus PA couplers, links, gateways, and interfaces to ABB DCS/SCADA, and maintain device libraries.
• Collaborate with electrical and control teams on EMI mitigation, cable routing, and panel earthing standards.
• Support interfaces with MCCs, VFDs, PLC skids, and plant SCADA/IMS/CMMS systems.
• Ensure all DCS SIS activities comply with plant safety standards, IEC requirements, and cybersecurity policies.
• Strengthen OT cybersecurity through access control reviews, patch management, and secure network segmentation.
• Develop a long-term DCS roadmap covering upgrades, expansions, and software/hardware obsolescence.

• Bachelor’s degree in Instrumentation & Control, Electrical, Electronics, or related engineering field.
• 5–10 years of experience in process automation, with strong hands‑on expertise in ABB DCS/SCADA systems within water, wastewater, or similar process‑plant environments.
• Proven experience in Profibus DP/PA commissioning, troubleshooting, and advanced diagnostics.
• Solid background in instrumentation for STP processes, including work in hazardous and corrosive (H₂S‑prone) environments.
• Familiarity with SIS/ESD systems (e.g., Pro Safe‑RS), alarm management practices, loop tuning, and historian/reporting tools.
• Experience working with CMMS platforms and IMS documentation requirements.
