Safety Instrumented System Offers Improved Connectivity

Yokogawa Electric Corporation released ProSafe-RS R3.02.20, an enhanced version of the ProSafe-RS safety instrumented system (SIS) that offers improved connectivity with the ProSafe-SLS SIS, enabling the status of both systems to be monitored onscreen by operators of the CENTUM VP integrated production control system. If a problem occurs anywhere in a plant, the sequence-of-event (SOE) data from both SISs will be displayed on an integrated screen at the operator terminals. Operators and maintenance engineers can use this data to identify and analyze the problem cause.

In addition, R3.02.20 offers enhanced support of widely used open communication protocols, improving connectivity with other companies’ SCADA*1 software, according to Yokogawa. Support of DNP3 in the ProSafe-RS R3.02.20 controller enables customers to replace and expand their systems in the field while continuing to use their existing SCADA infrastructure.
