TROUBLESHOOTING
POINT
1. When the special relay "Memory copy to other system status executed" flag
(SM1596) or the "Memory copy to other system completion" flag (SM1597) is
ON, memory copy will not be to other system status executed even if the
"Memory copy to other system start" flag (SM1595) is turned ON.
In this case, no error code will not be stored in "Memory copy target I/O No."
(SD1596) in the special register.
Turn OFF SM1596 or SM1597 if either of them is ON, then execute memory
copy again.
2. When a transfer target I/O No. other than the standby CPU module (3D1
H
) is
set to "Memory copy target I/O No." (SD1595) and memory copy is executed,
the "Unsupported transfer target I/O No. (error code: 4248
H
) will be stored in
SD1596.
In this case, memory copy will not be executed.
