Most safety instrumented functions only require a safety performance rating of up to SIL 2. However, most of today's safety PLCs are certified to SIL 3. Why can't you simply use a standard PLC configured to be safe in order to achieve your safety performance goals?

During this Innovation Session,  presenters:

• Explore how different technologies fail in different modes

• Discuss why SIL 3 safety PLCs might be needed for safety instrumented functions with SIL 2 performance requirements

• Analyze an accident where SIL 2 generic PLCs configured to be safe were used

The “golden rule” of functional safety design is that basic process control systems and safety instrumented systems (SIS) should function independently. However, in some cases, there are opportunities for combining your control and safety systems in one CPU.

During this Innovation Session, we will investigate:
 

• Why it’s recommended to keep protection layers independent (but not separated, divergent or asynchronous)

• Current industry standards and considerations (including those from IEC 61511; 2016, ANSI/ISA 61511; 2018, NAMUR and NFPA 85)

• How different process safety technologies address functional safety and cyber security

• Multiple application examples

Watch this educational session to learn how to simplify your safety application program, and comply with OSHA PSM (OSHA 1910.119): process safety management of highly hazardous chemicals.

Key points:

• Leveraging a  "cause and effect" diagram to reduce complexity and human error
• Generating a configuration report as part of the Safety Requirement Specification
• Automatically generating code in a virtual safety controller
• Verifying the application program as required by IEC 61511-1 Clause 6.3
• Generating a validation report for your application
• A live demonstration of the SIMATIC Safety Matrix will be presented

The more functionally safe a system is built, the less reliable it becomes. This is why Independent Protection Layers (IPL) higher than three orders of magnitude are to be avoided at all costs. During this webinar, you will explore:

• How Highly Managed Alarms and Safety Alarms are defined in the IEC 61511 Functional Safety Standard, IEC 62682 Alarm Standard and NE 165 Basic Process Control System Protection Layers
  
• How IPL alarms can be implemented in your DCS using SIMATIC Safety Matrix and F I/O modules
  
• About a typical API 556 application scenario where other instrumented IPL could reduce the burden of a Safety Instrumented Function by optimizing risk reduction

Watch this 45-minute session to hear two safety system experts debate their positions on alternative BMS designs to improve both safety and reliability.

Key Learning Points:

• Safety alarms (highly managed alarms) - standard ANSI/ISA 18.2 (IEC 62682) 

• Alarms as Independent Protection Layers - defined in standard IEC 61511 

• Control and safety in the same CPU - recommended practices NAMUR NE 165 and NFPA 85 

• A typical API 556 high pressure scenario where these principles are applied

How much automation is needed in a fired heater? Are all fired heaters the same in refineries and petrochemical plants? Explore these questions and many more by reviewing Annex A of the ANSI/ISA TR84.00.05 - Guidance on the Identification of Safety Instrumented Functions (SIF) in Burner Management Systems. Webinar goals include:

• Review the advantages of using safety-certified PLCs for BMS
• Review the advantages of automating different operational phases in Annex A application examples (pre-firing, light-off, post-firing and normal)
• Evaluate the performance of a Safety Instrumented Function (SIF) in a BMS application
