The ControlEdge remote terminal unit (RTU) process controller from Honeywell Process Solutions (HPS) is the first RTU to ISASecure Embedded Device Security Assurance (EDSA) Level 2 certification, says the company.

The certification recognizes the cybersecurity features of the ControlEdge RTU, which is used for remote automation and control applications such as wellhead monitoring in the oil and gas industry.

The assessment by independent ISO 17065-accredited certification body exida considered both the integrity of the RTU and its development life cycle, as well as communication robustness testing and functional and software development security assessments. Tests found that the unit was free of known cybersecurity vulnerabilities and robust against network attacks.

Honeywell’s RTU helps facilities manage complex distributed equipment while converting data from complex automation systems into relevant, actionable information.
