Yokogawa Electric has upgraded its Exaquantum Safety Function Monitoring (SFM) software, an OpreX Asset Operations and Optimization solution that helps identify whether actual operating performance meets safety design targets.
Improving health and safety is one of Yokogawa’s six sustainability focus areas.
SFM R3.35 provides continuous monitoring and evaluation of safety data to highlight deviations or failures in plant safety system performance.
This new version now supports the International Electrotechnical Commission (IEC) 61511 standard and includes several new features to help SFM users identify potential safety issues, optimize maintenance activities, and improve overall safety solution design.
SFM R3.35 enables users to monitor the effectiveness of the performance of defined safety instrumented systems against their design targets.
Yokogawa recognizes the continuous challenges that plant owners face in trying to efficiently maintain process safety integrity over the entire life cycle of their plant facilities.
As one component of a sustainable SIS solution, SFM automatically monitors operational safety data to quickly determine whether real-time operating data meets safety design targets and to track and analyze key safety performance metrics. Proof tests are recorded to track when they took place and identify when they reach their expiration date.
SFM assists plant managers by identifying any potential safety issues, reducing unnecessary maintenance activities, and improving the overall safety solution design.
- IEC 61511 compliant
- SFM R3.35 employs a cause & effect matrix to quickly verify the logic of SIF activations and final element (valves, vents, actuators, etc.) actuations to see if they match their configured or intended safety design, as required by the IEC 61511 standard.
- Enhanced proof testing
- A proof testing status function has been added to SFM R3.35 for the monitoring of the expiration dates of proof tests on SIFs and final elements. Users can also claim proof test credit based on actual demand on the SIS during operation, with the functionality to record when proof tests have taken place and their expiry date to help maintain the validity of the safety system.
- PHA-Pro compatibility
- Safety configuration data for layers of protection analysis (LOPA) using PHA-Pro® (a third-party software solution from Sphera) can be used to generate an initial SFM configuration file. A PHA-Pro export template exports information from the LOPA in a format that can be imported into SFM.
