itself using CMND(490).
FREAD(700) or FWRIT(701) are being exe-
cuted.
The program is being overwritten using a con-
trol bit in memory.
A simple backup operation is being performed.
Accessing File Flag
A34314

Use this flag as an execution condition to pre-
vent a file memory instruction from being exe-
cuted while another is in progress.
Memory Card Detected
Flag

EM File Format Starting
Bank
A344
Contains the starting bank number of the EM
Area that has been formatted for use as EM

EM Area has been formatted.
To convert the EM Area for use as file memory,
the PLC Setup’s EM File Memory setting must
be set to 1 and the EM File Memory Starting
Bank (0 to C) must be set. All EM banks from
the starting bank to the last bank will then be
formatted for use as file memory.
