1.2 System Frameworks
The AH500 series programmable logic controller is a medium type of programmable logic control
system. The execution speed and the memory capacity are increased. Besides, the complete
program development function of function blocks is supported. In order to meet users’ more
advanced application requirements, the AH500 series programmable logic controllers provide more
flexible system extension frameworks. Under such system frameworks, users do not need to use
several CPU modules to control the system because of the fact that there are too many I/O points or
the equipment is too far away. The completeness of the system is retained, and users can be more
efficient in developing the projects.
The minimum framework requirement for theAH500 system:
To create the AH500 system, one main backplane, one power supply module, and one CPU module
are needed for the operation of the CPU module.

Power supply

The common framework of theAH500 system (for original equipment manufacturers):
The AH500 system can meet most equipment development requirements in the application field of
original equipment manufacturers. Generally speaking, one eight-slot main backplane or one
twelve-slot main backplane is chosen. Some advanced equipment can be used with a six-slot
extension backplane or an eight-slot extension backplane under the original framework to increase
the number of I/O points and the number of axes, or decrease the wiring cost.

Note: Owing to the consideration to the data transmission speed, the motion control modules and
the network modules (exclusive of the serial communication modules) have to be installed
with the CPU module on the same backplane. Otherwise, the system can not operate
properly.
The common framework of theAH500 system (for system integration):
The AH500 system can meet most system control requirements in the application field of the system
integration. Generally speaking, the system framework is related to the positions of the equipments.
A control panel is usually placed among the equipments which are concentrated to save the wiring
cost. However, there is usually more than one concentration point, and the distance between the
concentration points is over 100 meters. If it is necessary for users to place more than two control
panels, the RTU modules are required. The remote framework of theAH500 system not only fills the
remote requirement, but also is combined with the extension of the local I/O. Under most conditions,
a control panel instead of a backplane can be regarded as a remote I/O station. In addition, the
backplanes, the power supply modules, and other modules are compatible with one another. The
convenience of planning the system is increased, and the difficulty of choosing the products is also
decreased.

Note: Users are provided with the special cables to connect the extension backplanes. The length of
a special cable can be up to 100 meters. They are also provided with the fiber cables which
are used with the special adapters. The length of a fiber cable can be up to 2 kilometers.

1.3 Operation of the CPU module
The CPU module is the nucleus of the AH500 system. It is responsible for not only the execution of
the logic program, but also the data exchange and the processing of the communication data. The
relation between the AH500 system and the external devices are illustrated below.

The operation of the CPU module is illustrated above. The system procedures related to the
initialization, the diagnosis, and the communication, and the program procedures related to the
external interrupts and timed interrupts are simplified. Users can refer to other manuals for more
information. The operation of the CPU module is described below.
