ANYBUS-S DPV1 Configuration

Hi,
We are using ANYBUS-S DPV1 With AC00M Controller in which already INPUTc 64 words and OUTPUTc 64 words are configured with 32 IW and QW respectively.
what is the maximum number of INPUTc 64 words and OUTPUTc 64 words this module can incorporate ?
Do refer images attached for reference.
I appreciate if i can get any reference/document of configuration of ANYBUS-S DPV1 with AC800M Controller.

Thanks in advance.
