CPU Module Scalability
The APAX family offers various CPU modules with different processors in order to meet
different requirement of control tasks.
 APAX-6571: Intel Atom CPU, 1.6 GHz processor
 APAX-5571: Intel Celeron M CPU, 1.5 GHz processor
 APAX-5570: Intel Celeron M CPU, 1 GHz processor
 APAX-5520/5620: Intel XScale PXA270, 520 MHz processor
System Composition
APAX-5000 series consists of power modules, CPU modules, couplers and I/O modules.
All I/O modules inserted on the backplanes can be stacked together and connected to CPU
modules or couplers to form a complete system. With the 1-slot or 2-slot backplanes,
users can select the appropriate I/O number depending on their need.
Flexible Topology for Expansion
APAX-5000 I/O modules are connected together via Ethernet bus. Each backplane offers
one expansion port. Using a standard Ethernet cable to connect the expansion port on
two backplanes, a remote expansion with local-bus speed is built, and the distance can
be up to 100 m. In addition, any standard Ethernet switch can be used between two
backplanes. Therefore, you can build line, tree or star topologies for I/O expansion --- all
with fast local-bus speed. The implementation of Ethernet switches not only enhances
the flexibility of I/O expansion, it also increases the expansion distance. For example, if
there are 3 Ethernet switches between two I/O stations, the expansion distance can be
at least 400 m. (When fiber optic ports are available on the Ethernet switch, the distance
can be much longer.)
High Density and Deterministic I/O
Up to 24 digital channels or 12 analog channels are provided on single module. With
such high density I/O numbers, the update time for data from 32 digital input modules
(up to 1536 digital input channels) can be guaranteed. The update rate is also guaranteed
to transfer data to 32 digital output modules (up to 1536 digital output channels). This
feature ensures system real-time ability.
Hot Swap I/O Design
Backplanes carry communication and power to I/O modules. This design makes the I/O
modules able to be hot swapped when the system is powered-on and running. Engineers
can easily change modules without shutting down the whole system. This saves the system
management and troubleshooting costs.
Intelligent I/O Module
APAX-5000 I/O modules can execute on-module processing and calculation, allowing
them to become intelligent I/O modules. Controlling LED status to display module
information or digital filters are a couple examples of leveraging the extra processing
capacity.
Reliable Clamp Type Terminal Blocks
All APAX-5000 I/O modules offer clamp type terminal blocks. Compared to traditional
screw type terminal blocks, clamp type terminal blocks can save wiring time up to 75%.
Clamp type terminal blocks have higher resistance to shock vibration, without wire damage
or measurable contact interruption. Besides, clamp type terminal block connections don't
require checking or retightening, which helps save wiring maintenance costs.
Software Support
APAX-5000 series software support can satisfy both PC-based and PLC-based
programmers. The C/C++ and .NET class library can satisfy the programmers who are
familiar with high level programming languages using Microsoft Visual Studio .NET.
The PLC-based users can leverage KW-Software Multiprog which supports IEC 61131-3
compliant PLC programming languages.
