Note If EM file memory is specified for the active CPU Unit’s EM Area with the PLC
When a file is written to the EM file memory in the active CPU Unit in a Duplex
System, the same file is simultaneously written to the EM file memory in the
standby CPU Unit.
Setup, the same banks will be specified for the standby CPU Unit’s EM Area
by means of duplex initialization.
The following table shows the operations of the EM file memory-related func-
tions.
Files are ordered and stored in the Memory Card or EM file memory accord-
ing to the file name and the extension attached to it. File names handled by
the CPU Unit (i.e., file names that can be read) are set as shown in the follow-
ing tables.

When a file is written to the active CPU
Unit’s EM file memory, the file is simul-
taneously written to the standby CPU
Unit’s EM file memory. FWRIT instruc-
tion execution is synchronized for the
active and standby CPU Units.
The FREAD instruction is executed for
both CPU Units, and the data read
from the active CPU Unit’s EM file
memory is used by both CPU Units.
