Yokogawa Electric Corporation announced that it has obtained ISASecure CSA Level 1 certification from the ISA Security Compliance Institute (ISCI) for its ProSafe-RS safety instrumented system, a product in the OpreX Control and Safety System family. This is the first time a safety instrumented system has obtained this certification. Yokogawa has long emphasized the importance of cybersecurity with its safety instrumented systems, and this certification is expected to give customers even greater confidence in the use of this product.
Yokogawa's ProSafe-RS safety instrumented system is certified for use in safety integrity level 3 (SIL3) applications. With regards to cyber security, it has held ISASecure EDSA certification since 2013. Replacing this certification program, ISASecure CSA certifies compliance with the IEC62443-4-2 and IEC62443-4-1 international standards pertaining to control device security. Receipt of this certification indicates that a product has been recognized by a third party as having security controls that conform to these international standards. Yokogawa also plans to obtain ISASecure CSA certification for the ProSafe-RS Lite SIL2 safety instrumented system, which was released in January of this year.
