The Ethernet Hot Standby system consists of two identical Modicon Quantum systems. Each Quantum system contains:
-
a Modicon Quantum Hot Standby with Control Expert controller (140 CPU 671 xx0), (140 CPU 672 xx0) or (140 CPU 678 61)
-
a remote I/O head
-
NOE 771 xx modules (no more than six)
-
a power supply
The Hot Standby modules are connected to each other via a fiber-optic cable. Both remote I/O heads are connected to the remote I/O network and to each other.
Schneider Electric recommends:
-
remote I/O networks use redundant cables (drops are not redundant)
-
switch connecting the NOEs to the network (available switches):
