Regardless of plant complexity or size, safety and security are a high priority for the process industry. Siemens SIMATIC PCS 7 and SIMATIC SIS Compact provide Safety Instrumented System (SIS) solutions specifically designed to protect your critical assets.
Using Certified PLCs as BMS for a Natural Draft Gas-Fired Multi-Burner Process Heater Following API 556 and IEC 61511
How do you determine how much automation is needed in a fired heater? Are all fired heaters the same in refineries and petrochemical plants? We will address these questions and 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, a reference on heater applications for refineries and petrochemical plants.
Integrated Safety Lifecycle Tools
All Siemens process safety systems are designed and built in accordance to relevant national and international safety standards (ISA, IEC, NFPA, API etc.) to ensure compliance.
Our system benefits include:
Reduce operator error - best-in-class local HMI for better operation and maintenance
Reduce risk - SIL-certified safety library
Improve plant availability - Flexible redundancy options
Achieve functional safety requirements - complete safety lifecycle tools
Studies show that incorrect specifications are the number-one cause of process-related accidents. Avoid these unnecessary risks by downloading the SIS specification that will help your safety system project move along smoothly.
7 reasons SIMATIC PCS 7 is your choice for process safety
Intuitive interface makes it easy to comply with OSHA's process safety management (PSM) requirements for documenting and managing your dedicated Safety Instrumented Systems (SIS)
Complete range of safety-rated field devices flexible enough to stand alone and operate as an independent Safety Instrumented System
Simple process safety with automatic self-diagnostics that remove the need for manual proof tests
Scalable I/O options for small, compact to large and remote applications
Secure SIL-rated communication protocols protect against unauthorized interference
Integrated handling of both safety and standard signals provides a cost effective motor management system for safety applications that require final control of low voltage process motors
Available flexibility to support multiple redundant architectures, preventing nuisance trips without compromising safety
SIMATIC SIS Compact - The Stand-Alone Safety PLC
SIMATIC SIS Compact was designed as a dedicated safety control system for Safety Instrumented Systems (SIS) based on selected system components of SIMATIC PCS 7 and the SIMATIC Safety product portfolio.
SIS Compact Benefits:
Reduced cost - The SIS Compact is designed as a stand-alone SIS without the DCS overhead
Low risk - Using the field-proven SIMATIC technology with over 30 years of SIS experience
Industry compliant - Certified by TUV for Safety (IEC 61508) and Security (IEC62443)
Reduced false trips – Fault-tolerant architectures provide high system availability
Simplified maintenance - Uses the latest state-of-art SIS tools (function block and cause-and-effect diagrams) for easy trouble shooting and MOC
Powerful - Can also support integrated control functions when physical separation isn't feasible or practical
Expandable - Supports the ability to network multiple systems together as your plant needs grow
Benefit from a wide range of applications
SIMATIC SIS Compact – designed for use in safety-critical applications in the process industry.
SIMATIC SIS Compact can be used for safety applications up to SIL 3, as per IEC 61508. In addition to the engineering tools, the SIMATIC SIS Compact also offers an optional operator package to provide and integrated HMI to operate, monitor and maintain your SIS.
Industry applications include:
- Burner management systems (BMS)
- Emergency shutdown systems (ESD)
- Fire and gas applications (F&G)
- High integrity pressure protection systems (HIPPS)
- Tank overfill prevention
- Cause & effect matrix programming and visualization option
Studies show that incorrect specifications are the number-one cause of process-related accidents. Avoid these unnecessary risks by downloading the following Burner Management Systems (BMS) specification that will help your safety system project move along smoothly.
SIMATIC Safety Matrix: The Safety Lifecycle Management Tool
SIMATIC Safety Matrix, the powerful cause-and-effect software for process automation, allows for significantly faster and more convenient configuration of safety applications. Designed to reduce costs and effort for engineering, commissioning and maintenance, this TÜV-certified safety lifecycle management tool can be used for applications up to SIL 3 according to IEC 61508.
- Flexibility: Can be used in all phases of the safety lifecycle
- Ease of use: Simple, intuitive operation and monitoring with no special programming skills required, making it possible to focus fully on the safety requirements of the plant
- Reduced plant downtime: Events and alarms are transmitted directly to the SIMATIC PCS 7 operator system
Choosing Functional Safety Instrumentation
Certified, prior use or both? Fundamentals of VDI 2180. Can you justify safety instrumentation?
Determining the equipment to use in safety instrumented systems (SIS) and the rules for maintaining them is one of the most difficult and controversial topics in the industrial SIS marketplace. Learn more from Siemens industry experts.
