The Control Systems Engineer – Valve PLC/SCADA Integration is responsible for developing, programming, and maintaining automated valve control systems across sanitary and utility processes. This mid-level role ensures seamless operation of valves used in batching, CIP/SIP, product transfer, and process safety through robust PLC logic and SCADA visualization. The engineer plays a key role in supporting hygienic compliance, process efficiency, and plant automation strategy by integrating valves and field devices with industrial control platforms.
Design and program PLC logic for valve actuation, interlocks, sequencing, and safety systems in accordance with P&IDs and process requirements.
Implement structured, modular code for valve clusters, mixproof valves, and redundant systems, including fail-safe states.
Configure PID loops and inter-process communication protocols (e.g., EtherNet/IP, Profibus, AS-i) for valve and sensor integration.
Develop SCADA/HMI interfaces for operator control and monitoring of valve systems, including alarms, diagnostics, and trend views.
Maintain and update graphics for CIP/SIP routing, flow diagrams, and valve status indicators to support production and sanitation teams.
Lead loop checks, IO validation, and commissioning of valve control systems during new installations, retrofits, and projects.
Troubleshoot field issues involving valve misfires, actuator faults, sensor mismatches, and SCADA communication errors.
Create and maintain control system documentation including IO lists, logic diagrams, network maps, valve configuration files, and FAT/SAT protocols.
Collaborate with QA and process engineering to validate automated valve performance against food safety and hygiene requirements (e.g., 3-A, EHEDG).
Work with process, mechanical, and utilities engineers to define automation scope and valve control strategy.
Interface with OEMs, integrators, and internal stakeholders to ensure consistent, standardized valve integration across sites.
