(5) Memory error factor %MW10.8, %MW10.9 (Read only)
System operation after a memory error has occurred
Any memory backup error resets the entire user memory area to 0 (zero). Note that in most cases, since %MX10.8.0 to
%MX10.8.3 are set to “ON” when a hardware fault has occurred, cycling the power source may cause a memory error to be
repeated.
(6) Application error factor %MW10.12, %MW10.13 (Read only)
