It is possiblein MONITOR or PROGRAM mode only.RUNNoMONITOROK! CautionBefore changing the contents of I/O memory, be sure that the changes will notcause equipment to operate unexpectedly or dangerously.
In particular, takecare when changing the status of output bits. The PC continues to refresh I/Obits even if the PC is in PROGRAM mode, so devices connected to output pointson the CPU Unit, Expansion Units, or Expansion I/O Units may operate unexpectedly.1, 2, 3...1.

They are possible in MONITOR or PROGRAM mode only. In MONITOR mode, the SV can be changed while the program is being executed.RUNMONITORNoOKPROGRAMOKThe timer or counter SV can be changed either by inputting a new value orby incrementing or decrementing the current SV.This operation can be used to input a new SV constant, as well as to change anSV from a constant to a word address designation and vice versa.
