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 Turns ON at startup or when the Unit is restarted if there is an error in the DM
Area data stored in flash memory. (This is not treated as an error and there is no
error code. Only this flag turns ON.)
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 Compiler error (non-supported instruction is used; fatal
error)
08 Turns ON when an address that does not exist in user
memory (e.g., the non-existent HR Area is used) is specified
(fatal error).
09 Turns ON when there is an error in flash memory (fatal
error).
Note: The user program, the general-purpose read-only
portion of the DM Area, the Unit Setup Area, and expansion
instruction data are saved to flash memory.
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
interruptions.
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)
