hitachi eh150 programming problem

, i used ladder editor  for windows to program hitachi eh150 cpu 208a
i did the program on offline mode then i switched to online mode and trying to
initialize cpu a message error said " can't excute while cpu is runnin
i need to stop the cpu to go on . i have read in manual that stop cpu is existed in
debug menu when switching to monitor case , but debug menu is inactive except set(G) .
when i press set(G) a message error said " key position is not remote
also there is a problem with on direct mode "program unmatched. "
thanks
