This safety instrumented system has cybersecurity protection

| By Mary Page Bailey and Gerald Ondrey

The ProSafe-RS safety instrumented system (SIS; photo), a product in the OpreX family, recently obtained ISASecure CSA Level 1 certification from the ISA Security Compliance Institute (ISCI). This is the first time a safety instrumented system has obtained this cybersecurity certification, says the manufacturer. Receipt of this certification indicates that a product has been recognized by a third party as having security controls that conform to international standards for control-device security. The ProSafe-RS safety instrumented system is certified for use in safety integrity level 3 (SIL 3) applications. This company also plans to obtain ISASecure CSA certification for the ProSafe-RS Lite SIL 2 SIS, which was released in January. — Yokogawa Corp. of America, Sugar Land, Tex.
