The following words and bits provide file memory status for Single CPU Sys-
tems or for the active CPU Unit in a Duplex CPU Systems. For a Only the
Memory Card in the active CPU Unit is accessed. For information on the CPU
Unit’s file memory-related status, refer to Read-only Words in Appendix B
Auxiliary Area Allocations.
ON if the CPU Unit’s battery is disconnected or its voltage is
low and the PLC Setup has been set to detect this error.
(Detect Low Battery)
ON if A40204 is ON in the right CPU Unit.
ON if A40204 is ON in the left CPU Unit.
The Memory Card type is output to A34300 to A34302.
(0 hex: No Memory Card; 4 hex: Flash ROM)
With a Duplex CPU System, the information depends on the
setting of duplex operation for the Memory Card, as shown
below.
• Memory Card duplex operation disabled: Memory Card
• Memory Card duplex operation enabled: Memory Card
Turns ON when a format error occurs in the first EM bank
allocated for file memory in the CPU Unit.
Turns OFF when formatting is completed normally.
ON when the Memory Card is not formatted or a formatting
error has occurred in the active CPU Unit.
ON when an error occurred while writing data to file memory
in the active CPU Unit.
ON when data cannot be written to file memory because it is
write-protected or the data exceeds the capacity of the file
memory in the active CPU Unit.
ON when a file could not be read because of a malfunction
(file is damaged or data is corrupted) in the active CPU Unit.
ON when an attempt is made to read a file that doesn’t exist
or an attempt is made to write to a file in a directory that
doesn’t exist in the active CPU Unit.
ON while any of the following operations is being executed in
the active CPU Unit. OFF when none of them are being exe-
cuted.
CMND instruction sending a FINS command to the local
CPU Unit.
FREAD/FWRIT instructions.
Program replacement using the control bit in the Auxiliary
Area.
Simple backup operation.
type for active CPU Unit is stored.
type is stored only when mounted in both CPU Units.
