The amount of link points that are utilized by its relay and register are the same, 1024pts, but the number of bytes differs: 128 bytes for the relay and 2048 bytes for the register. The A0J2HCPUP21 data link module uses for its memory storage an EPROM. The battery that is utilized is the A6BAT.

To link with other configurations, the A0J2HCPUP21 data link module, since it is a CPU module, can link using a cable to a smaller configuration used for extension purposes. After this is done, another cable may be utilized to link with the extension base. These bases can be of the A5[]B(S1) or it may be the A6[]B(S1). Placed upon the extension bases may be I/O modules or modules that have distinctive functions.
