Definition
An Engineering Workstation (EWS) is a privileged computer used to configure, program, update, and maintain ICS assets such as PLCs, RTUs, HMIs, and control servers.
Examples
- An engineer uses an EWS to modify PLC logic and download the change during a scheduled maintenance window.
- A technician applies a vendor-approved firmware update to controllers and backs up HMI projects from the EWS.

The EWS is the toolbench of industrial automation. It holds vendor programming suites, drivers, and project files used to build, change, and recover control systems. Because it can push logic, firmware, and configurations to critical devices, the EWS is one of the highest-value targets in OT. Security must balance safety and uptime with strict governance of who can use it, when, and for what.
