Honeywell’s ControlEdge programmable logic controller (PLC) received ISASecure Embedded Device Security Assurance (EDSA) Level 2 certification by exida, the ISO 17065-accredited certification body that conducted the assessment.

The certification recognizes the integrity of both the PLC and its development lifecycle. It includes communication-robustness testing as well as functional and software development security assessments. The ISASecure program has been developed by the ISA Security Compliance Institute (ISCI) with a goal to improve cybersecurity for industrial automation and control systems.

According to ISA, the ControlEdge PLC is the first of its kind to be awarded the ISASecure Level 2 certification. The Level 2 certification builds on Level 1 capabilities by providing additional security features such the detection of unauthorized changes and additional protection against denial-of-service attacks.

The controller is used in a balance-of-plant control applications such as water treatment, pump systems and material handling.
