Rockwell OptiSIS pre-engineered safety instrumented system

Rockwell Automation has introduced its OptiSIS solution, a pre-engineered safety instrumented system that can help ease deployment and reduce lead times for small and mid-sized process applications.

The OptiSIS solution is suitable for oil and gas, chemical and petrochemical producers with ageing process safety systems that are either non-compliant or can no longer be maintained.

The OptiSIS solution is designed for safety instrumented system applications of 50 or 100 I/O points, including emergency shutdown (ESD) systems, burner management systems (BMS) and high-integrity pressure protection systems (HIPPS). The version for applications of up to 100 I/O points will be available in the fourth quarter of 2015.

The pre-engineered OptiSIS solution is delivered ready to install, wire and configure, shortening the overall engineering time and eliminating the need for any programming. Users need only enter their logic scenarios into the system’s cause-and-effect graphical interface. The configurations are tested and can then be stored for verification against original safety function requirements — or used at a later date to restore the system to a known state.

The system accommodates a varying mix of digital and analog I/O types. Additionally, simplex I/O and fault-tolerant (dual) I/O versions are available to address different redundancy needs.

The system meets requirements up to SIL 3 and is compliant with IEC 61511/ISA 84.00.01. It uses ready-to-install, TUV-certified hardware and validated application software.
