Chapter 1 Introduction
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.
Main backplane (four-slot AHBP04M1-5A)
CPU module
Power supply
module
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.

Chapter 2 Programming
The wiring of the modules is described in detail below. (Please refer to AH500 Hardware Manual for
more information.)
2.3.1 Wiring the Power Supply Module
zThe alternating-current input voltage is within the range between 100 V AC and 240 V AC.
Please connect the power supply to the terminals L and N. If the 110 V AC or the 220 V AC
power supply is connected to the input terminals VS+ and VS-, the PLC will be
damaged.
zIn order to ensure that the 24 V DC external power supply is provided stably, it can be
connected to VS+ and VS-. If the PLC detects that the voltage of the external power supply is
lower than the working voltage, users can write a protective program. (Please refer to section
6.6 in AH500 Operation Manual for more information.)
zThe length of the wire connecting with the ground is 1.6 millimeters.
zIf the power cut lasts for less than 10 milliseconds, the PLC keeps running without being
affected. If the power cut lasts for long, or if the voltage of the power supply decreases, the
PLC stops running, and there is no output. When the power supply returns to normal, the PLC
resumes. (Users have to notice that there are latched auxiliary relays and registers in the PLC
when they write the program.)
zPlease use the single-core cable or the twin-core cable. The diameter of the cable used should
be with the range between 12 AWG and 22 AWG. The torque applied to the terminal screw
should be within the range between 5 kg-cm (4.3 Ib-in) and 8 kg-cm (6.9 Ib-in). Please use the
copper conducting wire. The temperature of the copper conducting wire should be 60/75°C.
zSafety wiring: The PLC controls many devices, and the activity of any device affects the
activity of other devices. If a device breaks down, the whole automatic control system goes out
of control, and the danger occurs. The protection circuit is as follows.
