Review of Quadlog Safety Review of Quadlog Safety PLC BasicsPLC Basics
What is QUADLOG? It is the safety PLC design for potentially dangerous applications.
Such as: Emergency shutdown systems Gas detection systems Fire detection systems Burner management systems
IMPT POINT: USED EXTENSIVELY AT CDF

CRYOGENICCRYOGENICCONTROLS IDEACONTROLS IDEA
THERE WILL BE TWO (2) CONTROL PACKAGES USED IN THIS FACILITES FOR CRYOGENIC PURPOSES:
1)Standard Tevatron Process Control Package• VME Based, POWER PC• All helium I/O resides here, that is compressor and refrigerator systems
• Any non-critical Hydrogen affiliated I/O may potentially reside here
2) Specialized Safety PLC• Used for Hydrogen I/O, FiRUS, ODH, flammable gas

QUADLOG has built-in features provide maximum safety and reliability. QUADLOG exceeds the safety of triple modular redundant (TMR) system with greater system reliability and extensive diagnostics. QUADLOG also incorporates continuous PID control, analog I/O, open communications, and a variety of operator interface options not typically available from a PLC.

The QUADLOG critical control system offers: • Increased safety with proven fail-safe characteristics and protected outputs • Higher system availability with the fault tolerance of quad redundancy, special self-testing software, and unique common cause defense mechanisms • Improved reliability with greater strength against industrial stressors and isolation between I/O subsystems • Decreased start-up time and minimized downtime with online diagnostics and detailed error reporting • Easier integration with other control systems via open communications

QUADLOG Protected Outputs ensure no single component failure can prevent a mandatory trip.
PROTECTED OUTPUT

If On-line diagnostics detect a failure in one side of the system (including input, processor and output), the other side will maintains control automatically and system remains available
Redundant control
