c)When the PC stops because of a power interruption

d)When the Clear Force Set/Reset Operation is performed

!Caution Before changing the contents of I/O memory, be sure that the changes will not cause equipment to operate unexpectedly or dangerously. In particular, take care when changing the status of output bits. The PC continues to refresh I/O bits even if the PC is in PROGRAM mode, so devices connected to output points on the CPU Unit or Expansion I/O Units may operate unexpectedly.
