Safety PLC systems bring the benefits of traditional PLC systems to complex safety applications, replacing the hard-wired relay systems typically required to bring automated processes to a safe state. Safety PLCs allow standard and safety-related programming to reside in a single controller frame, providing flexibility in programming and a familiar, easy-to-use environment for programmers. Our safety controller solutions provide open, integrated controls that will help ensure machine safety and protect your current control investments.
Rockwell's ControlLogix and CompactLogix series all have the function of safety PLC, and can also use the dedicated GuardPLC safety control system to meet the needs of customers on site.
5570 ControlLogix® 5570 controllers can be used in standard, safety and extreme temperature environments, and On-Machine models are suitable for process, motion, discrete and high availability applications. As part of the Integrated Architecture™ system, these controllers use Studio 5000 Automation Engineering & Design Environment™ and common network protocols. These high-performance controllers provide a common control engine with a common development environment for all control domains.
Compact GuardLogix® controllers are ideal for small to medium-sized applications requiring safety functions, motion control, and/or complex communications. These controllers offer integrated serial, EtherNet/IP™ or ControlNet™ channels and modular DeviceNet™ communications. They support up to 30 I/O modules and up to 16 axes of motion.
The GuardPLC™ safety control system provides superior speed in PLC throughput and network capabilities. These controllers comply with global PLC standards and global standards for functional safety. This series is ideal for applications that detect rotational speed, direction, zero speed, temperature, pressure and flow. These controllers communicate over a TÜV-certified safety Ethernet communication network for EN954 Category 4 and SIL 3 compliant safety applications.
With the increasing size of petrochemical plants, the continuous complexity of the process, the possibility of danger in the production process is also increasing. Once the production process is abnormal and improperly controlled, it will have serious consequences for personal and property safety. . Safety technology is an important basis and technical guarantee for safe production. The automated safety instrumented system can respond and protect the chemical production equipment and equipment in a timely manner due to possible dangers or improper measures. Defined safe shutdown conditions so that risks are reduced to an acceptable minimum and the safety of personnel, equipment and production facilities is guaranteed.
In ISA 84.01, this type of product used in the fields of Safety System and Critical Control is called Safety Instrumented System (SIS). SIS provides a safety protection layer for the normal operation of the enterprise. It is a safety instrumented interlocking system. It is called functionally related electrical/electronic/programmable electronic systems in IEC61508. The scope is wider, covering Emergency Shutdown Systems (ESD), Burner Management Systems (BMS), Fire and Gas Systems (F&G), etc.
As the country attaches great importance to the safe production of dangerous production equipment, the standard requirements for safety instrumented systems are clearly put forward, and these standards are gradually institutionalized: First, it has high reliability and sensitivity, and can issue interlocks in time in emergency situations. The second is to select the safety instrumented system of the corresponding safety level according to the protection needs of different device process safety levels; the third is that the safety interlock protection function module is always static during the production process, and does not require manual dynamic operation.
The OptiSIS system of Ningbo Jiechuang Engineering integrated with Rockwell Automation has the following features and advantages:
• Support HART, OPC, Modbus and other protocols
• Meets SIL 3 requirements
• G3 anticorrosion
• Flexible configuration of single, double and triple
