Yokogawa Electric Corporation (TOKYO: 6841) announces that it has obtained ISASecure CSA Level 1 certification from the ISA Security Compliance Institute* (ISCI) for its CENTUM™ VP integrated production control system, a product in the OpreX™ Control and Safety System family. With this certification, Yokogawa’s CENTUM VP integrated production control system and ProSafe-RS safety instrumented system now both conform to the latest international security standards. In addition, the company has developed an enhanced version of ProSafe™-RS Lite that meets both explosion protection and marine standards, and an updated version of the Plant Resource Manager (PRM™) software that supports this latest version of the ProSafe-RS Lite.
Due in part to factors such as the increased reliance on remote system access during the COVID-19 pandemic, cyberattacks on production facilities are on the rise worldwide and are growing ever more sophisticated, and this is driving a rising awareness of the need for compliance with international standards. Components that receive ISASecure CSA certification conform to the IEC 62443-4-1 and IEC 62443-4-2 international standards pertaining to security for industrial automation and control systems. The ProSafe-RS safety instrumented system, which conforms to safety integrity level SIL3, and the ProSafe-RS Lite, which meets SIL2 standards, obtained ISASecure CSA Level 1 certification in May and July 2021, respectively.
For CENTUM VP to qualify for ISASecure CSA Level 1 certification, a cyclic redundancy check function has been added that periodically diagnoses the integrity of the programs and databases on a plant’s field control stations. If an error is detected, a system alarm is issued. Upgrading to the latest CENTUM VP R6.09 also enables operators to access Collaborative Information Server screens from their human interface stations, thus enabling the acquisition in real time of data on the operational status of equipment and devices.
