If the Process value went to over range value due to any reason and frequently triggering alarm on the DCS or SCADA. To avoid this frequent alarm if the DCS or SCADA scanned off or shelving facility is locked, some technicians remove the 24v supply in transmitters then it will trigger alarm input open as well as it will show IOP on the face plate of the this tag number instead of normal.
