SR 249 00 Turns ON when there is an error in the
Unit Setup Area read when the power
supply is turned ON (non-fatal error).
01 Turns ON when there is an error in the
Unit Setup Area read when operation
starts (non-fatal error).
02 Turns ON when there is an error in the
Unit Setup Area read at any time (non-
fatal error).
03 Turns ON when there is an error in the
initial setting data that is transferred
from the CPU Unit's DM Area memory
allocations (non-fatal error).
04 General-purpose READ/WRITE DM data in Flash memory (DM 0000 to 6143) sum
error/ladder library data sum error. Turned ON in the following situations:
• At occurrence of general-purpose READ/WRITE DM area in Flash memory sum
error.
• At ladder library data sum error
05 Constant Cycle Time Exceeded
Turns ON when the cycle time exceeds the constant cycle time set in the Unit
Setup Area (DM 6619).
06 User memory capacity exceeded (fatal error)
07 Compile error (unsupported instruction)/unusable instruction
in ladder library error. Turned ON in the following situation:
• At occurrence of a compile error (unsupported instruction)
• At creating a ladder library with programs that contains
instructions which cannot be used in libraries
08 Turns ON when an address that does not exist in user mem-
ory (e.g., the non-existent HR Area is used) is specified (fatal
error).
09 ON at Flash memory error/Flash memory sum error at trans-
ferring data in memory card to Flash
Trned ON in the following situations:
• At Flash memory error
• Flash memory sum error at transferring data in memory
card to the Flash.
• At sum error of offset/gain adjustment value for analog input
and analog output.
10 A checksum error has occurred in the general-purpose read-
only portion of the DM Area (DM 6200 to DM 6599) (fatal
error).
11 Turns ON when all of the settings in the Unit Setup Area (DM
6600 to DM 6655) are reset after a checksum error has
occurred there (fatal error).
12 Turns ON when a checksum error occurs in user memory
(program area), or when an attempt to execute an illegal
instruction is made (fatal error).
13 Turns ON when all of the expansion instruction data is reset
after a checksum error has occurred there (fatal error).
14 Turns ON when it is impossible to hold data that should be held at power interrup-
tions.
15 CPU Unit Error Flag (non-fatal error)
Turns ON when any of the following errors occurs:
Fatal CPU Unit error (Unit error code: 0A), CPU Unit WDT error (Unit error code:
0B), CPU Unit monitor error (Unit error code: 0C), bus error (Unit error code: 0D)

DM 6614 (Unit Setup Area
error) is stored in

When any of the
errors on the left
occurs, a memory
error is generated
at the Customiz-
able Counter Unit
and Unit operation
stops. Unit error
code F1 is stored in
SR 23500 to
SR 23507.
