The following is the list of special relay areas relating to the memory dump function.
*1 The CPU module where this function can be used supports these special relay areas.
CPU module database access function
The following is the list of special relay areas relating to the CPU module database access function.
*1 The CPU module where this function can be used supports these special relay areas.
No. Name Data stored Details Set by (setting timing) CPU
SM1472 Memory dump in progress Off: Memory dump not
executed
On: Memory dump in
progress
Turns on if memory dump is in progress,
and turns off if memory dump is not
executed. S (Status change) Rn
*1
SM1473 Memory dump completed Off: Not completed
On: Completed Turns on at the time when collection of the
data and save to the SD memory card are
completed after the establishment of the
trigger condition. Thereafter, the ON state
remains even if memory dump is executed
again. If the trigger condition is established
again, On changes to Off. S (Status change) Rn
*1
No. Name Data stored Details Set by (setting timing) CPU
SM1497 Memory card free space
flag for CPU module
database Off: 20MB or more free
space
On: Less than 20MB free
space
Turns on when the free space of the SD
memory card storing the CPU module
database is 20MB or less. S (Status change) Rn
*1
SM1498 CPU module database
start-up flag Off: Before start-up
On: After start-up Turns on only when the CPU module
database access function is enabled by the
module parameter setting and the database
can be accessed. S (Status change) Rn
*1
SM1499 CPU module database
start-up failure Off: Not failed
On: Failed Turns on only when the CPU module
database access function is enabled by the
module parameter setting but the database
start-up is failed. S (Status change) Rn
*1
