active CPU Unit will not be switched. Because of this, operation will not con-
tinue if an error that would cause the CPU Unit to be switched occurs during
duplex initialization, including CPU errors, memory errors, fatal Inner Board
errors, program errors, exceeding the cycle time limit, and execution of FALS
instructions).
Duplex refreshing is used to transfer errors detected by the active CPU Unit or
the status of special flags and bits changed by the active CPU Unit to the
standby CPU Unit. It is performed only in Duplex Mode.
The CPU Unit has three operating modes that control the entire user program
and are common to all tasks.

Programming
Programs are not executed and preparations, such as creat-
ing I/O tables, initializing the PLC Setup and other settings,
transferring programs, checking programs, force-setting and
force-resetting can be executed prior to program execution.
Programs are executed, but some operations, such as online
editing, forced-set/reset, and changes to present values in I/O
memory, are enabled for trial operation and other adjust-
ments.
Programs are executed and some operations are disabled.
