4. Larger program capacity and memory

Program capacity
AH500 basic series CPU module (AHCPU500/510/520/530): 32/64/128/256K steps.
AH500 advanced series CPU module (AHCPU501/511/521/531): 48/96/192/384K steps.
Providing with a wider module selection for users to select a suitable CPU module according to their
program capacity needs.

Memory
AH500 basic series CPU module (AHCPU500/510/520/530): 16/32/64K words of memory and
64/256/512/1024 function blocks to be declared.
AH500 advanced series CPU module (AHCPU501/511/521/531): 24/48/96/128K words of memory
and 512/1024/2048/4096 function blocks to be declared.
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.
X0
D0

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.
AH02HC-5A, AH04HC-5A, AH05PM-5A, AH10PM-5A, AH15PM-5A, and
AH20MC-5A
Extending the communication interface (*There are multiple interfaces. All
network modules can be installed on the main backplane except AH10SCM-5A
and AH15SCM-5A.)
AH10EN-5A, AH15EN-5A, AH10SCM-5A, AH15SCM-5A, AH10DNET-5A,
AH10PFBS-5A, AH10PFBM-5A, and AH10COPM-5A
It is installed on the main backplane as a remote terminal unit. (*It supports
multiple communication interfaces.)
