In PROGRAM
The right CPU Unit is the active (i.e., controlling)
CPU Unit.
Either the right CPU Unit is on standby or the
CPU Unit is stopped.
The right CPU Unit is operating (i.e., in RUN or
MONITOR Mode).
Either the right CPU Unit is being initialized for
duplex operation (transferring or verifying duplex
data) or the CPU is waiting.
While this indicator is flashing, neither of the
CPU Units will begin operation.

2.
A CPU error has occurred at the right CPU Unit.
One of the following operation switching errors
has occurred at the right CPU Unit.
Memory error
Program error
Cycle time overrun error
FALS instruction executed
Fatal Inner Board error (Process-control CPU
Units only)
The right CPU Unit is in PROGRAM Mode, or a
fatal error other than those indicated by a lit or
flashing red indicator has occurred.
Mode
If “Run Under Duplex Initial” in the PLC Set-
up is set to “Start running during initializa-
tion” only the active CPU Unit will start
running during duplex initialization.
This indicator will flash even if a duplex bus
error or a duplex verification error occurs
when the power is turned ON.
