The Quantum Hot Standby is an industrial control platform intended to provide automatic redundancy for a wide range of conditions. The main components of the system are two PLCs called the "Primary" PLC and the “Standby” PLC.
By being programed to detect and respond to defined system conditions, the Quantum Hot Standby system automatically allows the standby controller to take over the process control thus becoming the new primary controller. This transition, called the "switchover", takes place in a short time (the length of the watchdog plus one program cycle).
The Quantum Hot Standby system:
-
increases the system availability of your remote stations, allowing you to conduct maintenance operations in a main rack while the remote drops continue to be controlled
-
provides control redundancy for Quantum Ethernet I/O and/or S908 Remote I/O systems
-
offers a user-friendly development environment compatible with IEC 6113 - 3
-
allows creation of an high-availability application program almost as easily as for a standalone PLC and requires few changes from your normal programming methods
