The FCP270 flattens and simplifies the I/A Series
architecture. The I/A Series architecture only requires
field enclosures plus workstations and Ethernet
switches. For more information on The MESH control
network architecture, refer to PSS 21H-7C2 B3.
The field-mounted FCP270 is an integral part of the
highly-distributed control network where controllers
are closely aligned to specific process units mounted
in close proximity to their I/O and the actual
equipment being controlled. Coordination between
process units takes place via a fiber optic 100 Mbps
Ethernet network.
The FCP270 is packaged in a rugged, die cast
aluminum housing that does not require venting due
to its efficient design. The FCP270 is CE certified,
and it can be mounted without expensive special
cabinets to prevent electronic emissions. The
FCP270 can be mounted in Class G3 harsh
The unique and patented fault-tolerant operation of
the FCP270 greatly improves reliability relative to
other process controllers. The fault-tolerant version of
the FCP270 consists of two modules operating in
parallel, with two Ethernet connections to The MESH
control network. The two FCP270 modules, married
together as a fault-tolerant pair, provide continuous
operation of the controller in the event of virtually any
hardware failure occurring within one module of the
Both modules receive and process information
simultaneously, and faults are detected by the
modules themselves. One of the significant methods
of fault detection is comparison of communication
messages at the module external interfaces.
Messages only leave the controller when both
controllers agree on the message being sent (bit for

bit match). Upon detection of a fault, self-diagnostics
are run by both modules to determine which module
is defective. The non-defective module then assumes
control without affecting normal system operations.
This fault-tolerant solution has the following major
advantages over controllers that are merely
 No bad messages are sent to the field or to
applications using controller data because no
message is allowed out of the controller unless
both modules match bit for bit on the message
being sent.
 The secondary controller is synchronized with the
primary one, which ensures up to the moment
data in the event of a primary controller failure.
 The secondary controller will have latent flaws
detected prior to any switchover because it is
performing exactly the same operations as the
primary controller.
Fault-tolerant FCP270 modules connect to a pair of
fiber optic splitter/combiners (see Figure 1) that
connect to Ethernet switches in The MESH. For each
module, the splitter/combiner pair provides separate
transmit/receive fiber connections for Ethernet
switch 1 and 2. Fiber cables are connected so that
the splitter/combiners pass inbound traffic from either
switch to both modules, and pass outbound traffic
from the primary module to either switch.
The splitter/combiner pair mounts in an assembly
that fastens to the baseplate. The splitter/combiner is
a passive device that uses no electrical power.
The I/A Series architecture uses The MESH control
network with 100 Mbps data communications
between the FCP270s and the Ethernet switches
(see Figure 2).
