The high availability value, systems of hot standby and controls is calculated by their improved functionality under demanding situation. This means the application can continue running to monitor the system without shutting it down. And it means the Quantum PLC constantly measures up in vital situations. Additionally to standard functions of Quantum hot standby, this new PLC Quantum can be used for systems of SIL3 hot standby …to offer high availability for the CPU. Controlling the capability of the standby PLC – to capture from the primary – is expert in less than two logic scans.
Accomplished high accessibility for the I/O is also potential with the PLC Quantum, easy by using the I/Os safety in an unnecessary manner.
The PLC of SIL3 Quantum also offers added internal system testing and diagnostics, growing coverage of diagnostic. Its architecture internal offers two shutdown paths and lets double code execution and generation that notices both systematic errors in generation of code, as well as implementation and in the random access memory (RAM) and random errors in the CPU.
The PLC of SIL3 Quantum is qualified by the high-status TÜV Rheinland Group for use in appliances up to and involving SIL3 based on IEC 61508. This qualification confirms that the Quantum is meeting with the following standards:
• Programmable Logic Controllers (IEC 61131):
• Boiler protection of European standard: PR EN 50156 and U.S. standards: NFPA 86 and NFPA 85
• Electrical/electronic/programmable electronic safety-related systems Functional safety (IEC 61508),
• Fire detection and fire alarm systems (EN 54),
• Gas burners and gas burning appliances with or without fans in automatic gas burner control systems (EN 298).
The PLC of SIL3 Quantum is planned with module safety, which does specific functions safety. Nevertheless, the system also sustains TÜV Certified modules of non-interfering, permitting the user to control the application of safety. In contrast to safety modules, the modules of Quantum non-interfering are not utilized to perform any safety functions.
