Quantum Hot Standby
The Quantum Hot Standby controller implements high system availability using redundant hardware and by automatically switching over to the Standby (backup) hardware when certain defined system events are detected. While your prior PLC experience is very important to the proper use of this system, you need to become familiar with new concepts, practices, and restrictions to properly implement and manage the Quantum Hot Standby's redundancy.
NOTE: Users of Premium Hot Standby, Quantum legacy or other redundant systems should be aware that differences exist between the redundancy provided by these systems and that provided by the Quantum Hot Standby system. The differences include terminology, the conditions for switching to the standby system, system requirements and restrictions, and so on.
