Communications by
programs using the CPU
shared memory
Not supported
Data communications is performed
by using the TO, S.TO, FROM
instructions, and instructions using
the cyclic transmission area device
(U3En\G).

Scan time
Factors that increase scan
time
• Writing data during RUN
• Time reserved for
communication processing
• Writing data during RUN
• Time reserved for communication
processing
• Refresh processing among CPU
modules in the multiple CPU
system
• Waiting time

Parameter
Parameters added for a
multiple CPU system
Not supported
• Number of CPU modules
("Multiple CPU Setting")
• Control PLC setting ("I/O
Assignment")
• Out-of-group I/O setting ("Multiple
CPU Setting")
• Operation mode when a stop
error has occurred in a CPU
module ("Multiple CPU Setting")
• Communication area setting
("Refresh Setting")
• Settings of some parameters
must be the same for all the CPU
modules while others can be set
individually for each CPU module.
