DUPLEX RUN (Green)
Lit during normal duplex
operation
DUPLEX BUS ERROR (Red)
Lit if an error occurs in the Duplex
System. When a DUPLEX BUS
ERROR occurs the active CPU
switches the system from a Duplex
System to a Simplex System.
VERIFY ERROR (Red)
Lit if the programs in both CPUs are
not the same. When a VERIFY
ERROR occurs, the active CPU
switches the system from a Duplex
System to a Simplex System.
CPU ON/OFF switches
Use these switches to supply power to
each of the CPUs. To operate the CPU,
move the corresponding switch to the
ON position. When replacing the CPU,
move the corresponding switch to the
OFF position, and remove the CPU
from the Rack. Note that power is not
supplied to the CPU whose corre-
sponding switch is OFF.
Duplex Unit (C2000H Duplex)
I/O Control Unit
I/O Interface Unit
INITIAL SET
The Duplex Unit shown below must be mounted to the CPU Rack in order to
operate the Duplex System. The following indicators and switches are located
on the front panel.
An I/O Control Unit must be mounted to the CPU Rack in order to connect the
CPU Rack to an Expansion I/O Rack. In C1000H and C2000H Simplex Sys-
tems, the I/O Control Unit is mounted to the CPU Rack. In the C2000H Duplex
System, the I/O Control Unit is mounted to the I/O Rack. An I/O Control Unit can
be mounted even if no Expansion I/O Rack is used.
An I/O Interface Unit is needed on each Expansion I/O Rack, in order to expand
the PC. If there is not an I/O Interface Unit on each Expansion I/O Rack, data
communication cannot take place. The I/O Interface Unit is mounted to the left-
most I/O position on the Expansion I/O Backplane.
ACTIVE CPU (Green)
Indicates which CPU is active.
CPU RUN (Green)
Lit when the active CPU is
operating normally.
WAITING (Green)
This indicator is lit on three different
occasions:
(1) While the program in the Duplex
System is being verified (1 to 20
seconds)
(2) When the start input is not applied
to the CPU
(3) When there is a failure in starting
the Duplex System
PROGRAM (Green)
Lit when both CPUs are in the
PROGRAM mode
CPU ERROR (Red)
Lit when an error occurs in the
CPU. Operation stops and the
RUN indicator is not lit.
MEMORY ERROR
Lit if an error is found in the PC
program
