5. Devices which can be used conveniently in a program
 An AH500 series CPU module is equipped with devices which can be used conveniently in a program.
Users can flexibly specify a bit in a word device, e.g. D0.0, X0.0, and Y0.0. Owing to that bits in a word
device can be specified, these bits can function as contacts and coils.

 Users can access the state of DX0.0 and that of DY0.0 in a program. The state of DX0.0 and that of
DY0.0 are not limited by scan time. They are refreshed immediately in a program.
