2.1.4 Measures for Duplexing
Within a STARDOM system, the following components can be duplexed:
CPU of FCN-500
Power supply module of FCN-500 or FCN-RTU (used long base module only)
SB bus of FCN-500
Control network (control LAN) of FCN-500
Communication application
Check precautions described below for duplexed system components.
● FCN-500 Operation When Configured with Duplexed CPU
The operation specification and precautions applicable when the CPU of an FCN-
500 is duplexed are given in the following IM and TI documents:
Section B1.3.3, “Precautions on the Creation of Control Applications” of IM
“STARDOM FCN/FCJ Guide”
Chapter C2, “Duplex CPU Module (FCN-500)” of IM “STARDOM FCN/FCJ
Guide”
Section 7.2, “Operation using Duplex FCN CPU Modules" of TI “FCN-500
Technical Guide”
● FCN-500 and FCN-RTU Operation When Configured with Duplexed
Power Supply Module
Duplexing of the power supply module can be achieved by simply installing two
power supply modules on a long base module.

For details on the operation specification of an FCN-500 configured with duplexed power supply
module, see Section 3.1.2, “Power Supply Module” of TI “FCN-500 Technical Guide,” Section 3.1.2,
“Power Supply Module” of TI “FCN-RTU Technical Guide.”
● FCN-500 Operation When Configured with Duplexed E2 Bus/SB Bus
Duplexing of the E2 bus/SB bus can be achieved simply by configuration using
Resource Configurator.

For details on the operation specification of an FCN-500 configured with duplexed SB bus, see
Section 3.4, “SB Bus Repeat Module for FCN” of TI “FCN-500 Technical Guide.”
