Installation of an I/O Station with redundant FCIs requires two CI820 FCIs and a
TB815 Interconnection Unit (
Figure 2-4
). They are connected to the I/O modules of
the base cluster by an electrical ModuleBus extension cable. From the TB815
ModuleBus connector, a TK801V0xx cable is connected to the first MTU via a
TB806 Cable Adapter-in module.
The redundant FCIs can either be mounted on a separate DIN rail or the same one as
the I/O modules. Room must be allowed to the left and right of the FCIs for
disconnection from the TB815 for removal (
Figure 2-5
).
The total length of the ModuleBus extension, from the TB815, and ModuleBus
segments of the I/O modules must not exceed 2.5 meters (8.2 feet).
