Memory error factor %MW10.8, %MW10.9 (Read only)
Notes:
1) This bit is also set to “1” when an error occurs in the user ROM card.
<System operation after a memory error occurs>
If a memory backup error occurs, the entire user memory area is reset to 0 (zero). When any of the bits
%MX10.8.0 to
%MX10.8.3 is set to ON, there is a possibility of a hardware fault. Therefore, even if the power is turned OFF and then ON
again, a fatal fault may recur due to a memory error.
