3.2.4 I/O Addressing of AH Motion CPU
The I/O addressing between AH Motion CPUs and AH500 I/O modules installed on the motion backplane is a part of the
CPU specifications. The range of I/O addressing of AH Motion CPUs is explained in this section.
Software-defined address
Every AH motion CPU supports software-defined addresses between AH Motion CPU and its I/O modules. As a
default setting, a starting address is given by the software and I/O addresses are automatically allocated according to
the starting address. For example, AH16AM10N-5A, digital input module with 16 inputs, takes the input device range
of 16 bits, starting from Xn.0 (Xn.0~Xn.15).
User-defined address
If you want to define the I/O addresses according to actual needs, you can assign a starting address to an input/output
module by software. You can benefit from the user-defined addresses that allow you to obtain a flexible and
customized program. The available user-defined addresses for each I/O module will be listed later.
