FA-M3可编程控制器：

The Range-free Multi-controller FA-M3 is a next-generation programmable
controller, which achieves high performance through its ultra high-speed
processing and stable control features. It incorporates a space-saving compact
design, supports versatile ranges with cover for up to 8192 input/output points,
and is equipped with a variety of advanced modules, which can be used to
configure a wide range of applications.
With the FA-M3, decreased total cost of ownership （TCO） can be realized
through openness, improved functions and reduction in the size of machines
and facilities.
Features
The increased speed of the FA-M3 has been achieved as a result of adopting
the concept High Speed IPRS which is based on four factors; Instruction,
Process, Response and Scan. This contributed to increased accuracy of
instruments and productivity. The FA-M3 has also inherited structured
programming and uses an “object ladder*” to create an efficient total design, all
the way from planning to maintenance.
*: “Object ladder” is a program development concept aimed at dramatically improving customization
efficiency by integrating programs and devices into independent objects （e.g., blocks） on function
basis.
Ultra-high Speed Processing
The high-speed instruction processing capability of the FA-M3 makes it ideal for
applications that require high speed and quick response.
- The F3SP28 and F3SP38 CPUs achieve a scan time of 1 ms for a 6K steps
program*.
- The F3SP53, F3SP58, F3SP59, F3SP66 and F3SP67 CPUs achieve a
scan time of 1 ms for a 20K steps program*.
*: The scan times mentioned above can only be a achieved under specific conditions and vary
depending on the contents of the program and system configuration.
Sensor Control Function
This function allows one CPU to perform a parallel operation at a minimum scan
time of 200 μs while carrying out a main scan during program operation. It
enables one block of the program to be executed at high-speed and fixed
intervals independently of a main scan, which features high performance and
advanced functionalities.
Built-in Network Function （when using F3SP66, F3SP67）
These sequence CPU modules have a built-in network function, which
complements high-speed control with fast access and storage of large files.
With pre-installed support for a wide range of common communication
protocols, it addresses diverse application network requirements, and enables
transfers of large files.
Multiple CPUs
The FA-M3 can accommodate up to 4 CPUs in one base module depending on
the system size, program size and CPU aptitude. The supported CPU modules
include sequence CPU modules as well as BASIC CPU modules.
Program Reusability
Object ladder allows integration of programs with devices into components on
function basis. This improves the reusability of user software and efficiency of
machine custom design.
- Local Device
Devices used as variables in designing blocks or component macros have
been compley independent. The same name devices can be recognized
as the different devices so that analyses and adjustment of the device
structure for reuse of ladders are not necessary.
- Index View
The view of a ladder program, except for comments on circuits, can be
hidden or shown by collapsing or expanding as necessary. This gives better
visibility and allows detailed debugging while allowing for an understanding
of the whole flow of the program, which improves debugging efficiency.
- Windows Environment
The FA-M3 incorporates many functions, such as OLE, which run under the
Windows environment. This allows data such as comments and tag names
to be exchanged with Microsoft Excel, and ladder diagrams to be
exchanged with Microsoft Word using drag-and-drop operations.
Open Network
The FA-M3 supports open network protocols such as Ethernet, FL-net,
DeviceNet, AS-interface, PROFIBUS-DP, GP-IB, RS-232-C/422 and NEXUS,
and provides a range of modules for use on a variety of networks ranging from
field networks to system configuration networks.
I/O Configuration
Up to Seven Additional Subunits for I/O Extension
Up to 8192 inputs and outputs can be processed （for F3SP35, F3SP38,
F3SP58, F3SP59 and F3SP67）.
