TROUBLESHOOTING
POINT
1. The memory card setting status consistency check does not include the
memory card capacity check.
When using memory cards of different capacities, check the capacity required
for the actual control.
2. If the special relay "Card removal/setting enable flag (SM609) is turned on
and the memory card is changed during redundant system operation, an error
does not occur since a memory card setting status consistency check is not
performed.
However, a memory card setting status consistency check is executed if both
systems are powered on simultaneously or unreset (RESET/L.CLR switch is
set to the neutral position) simultaneously.
When changing the memory card during redundant system operation, set the
memory card of the same type in each system.
