Introduction
The AH500 system configuration is composed of a CPU module, power supply modules, digital input/output
modules, analog input/output modules, temperature measurement modules, network modules, motion control
modules, a main backplane, extension cables, and extension backplanes. Besides, an SD card is optionally
used.
A main backplane can be connected to an extension backplane through the interface on the left side of the
main backplane, the interface on the left side of the extension backplane, and a Delta extension cable. For a
CPU module or a RTU, a main backplane can be connected to seven extension backplanes at most through
the interfaces on the backplanes. Therefore, if there is a CPU module and there are several RTUs, not only
the CPU module can be connected to seven extension backplanes, but also every RTU can connect to seven
extension backplanes.
There are two ports on an extension backplane. The upper port is used to connect to a superior backplane,
and the lower port is used to connect to an inferior backplane.
