From EVOLUTION to REVOLUTION
The FA-M3 has reborned as the FA-M3 R,
to revolutionize the users' equipment.
for Revolution!
FA-M3 R is a new generic name for FA-M3 controllers containing one or
more of the brand new, ultra-fast four CPU modules.
FA-M3 R can simply be called the "M3R".
FA-M3 R and FA-M3 have upward compatibility.
Introduction to FA-M3
The design concept was to increase the speed of the FA-M3. The new high-
speed Instruction-Process-Response-Scan, or High-speed IPRS, in the FA-M3 R
was designed to achieve this objective.
Extensive studies were conducted to meet every requirement including ultra-high-
speed control, steady dispersion-free control and improved networking functions
including link control. The FA-M3 R is Yokogawa's ideal controller for next-
generation equipment, delivering even greater accuracy and productivity.

consider the processing time when programming.
* Executed instructions means the average number of instructions executed in 1 µs by PLC.
Why is high-speed processing necessary?
•
To carry out complicated calculations (with
application instructions) quickly
•
To stabilize mechanical control of higher
speed for higher productivity
•
To allow human-interface and diagnostic
programs to be enhanced, thus providing an
easier interface for the operator
•
To reduce unstable actions during each scan
time by network servicing

Why does a controller need to be smaller?
• To provide ample room for additional modules
• To allow installation of the controllers without affecting the machine design and
safety of the user factory (allowing perspective facilities)
• To help standardize control panels
• To reduce the size of the control panel to be minimized regardless of the
controller scale
• To reduce costs

Design concept: PLC is a substitute for relays
The FA-M3 R is packaged into the size of usual relays and conductors, and is designed for installation in the
same row with those inside a panel, thus allowing effective internal design of the panel.

Processing
speed per
instruction
• High-speed execution of instructions easily handles high-speed processing and response.
(Scan time of 1 ms for a 20K step program when using an F3SP53 or F3SP58)
• Sensor control function enables quick scan (input Æprogram execution Æoutput)
besides normal scan . This allows to have stable input/output response of 400 µs (200 µs
x 2). (when using an F3SP28, F3SP38, F3SP53 or F3SP58).
• Inheriting the structured programming, object ladder programming is adopted as a
dramatically upgraded programming language that facilitates program development and
modification (for the F3SP28, F3SP38, F3SP53 or F3SP58).
• User-defined macro instructions can be created and registered.
• Enriched functions, such as forced set/reset that are not affected by the results of
program computations as well as a scan operation, facilitate program debugging and
modification.
• The PROGRAMMER port (connection port for programming tool) supports a personal
computer link, allowing linkage to upper-level computers and display units without a
personal computer link module (at maximum baud rate of 115K bps for the F3SP28,
F3SP38, F3SP53 or F3SP58).
• Programs and data can be stored in an optional ROM pack, which is useful when
performing program replacement and making many copies of the same program on site.
• Protect function is provided to prevent programs from being read and copied by
unauthorized persons.
Note: The F3FP36-3N is used for both SFC and ladder programs (ladder programs only is available), and supports
neither index modification, scan operation, personal computer link, user log, ROM pack nor program security.

• Useful for communication tasks or high-level computations that are not easily controlled by
a ladder program.
• Can configure as a BASIC controller since a BASIC CPU module alone can be used
without a sequence CPU module.
• When installed in slots 2 to 4, BASIC CPU modules work as add-on BASIC CPU modules
for a sequence CPU module.
• Can directly access input and output modules.
• Can exchange data with ladder programs and synchronize with ladder programs by using
events.
• Allows structured programming using subprograms.
• Can access common data with a personal computer link module (can also connect a
display unit and access data via Ethernet or modem).
• The PROGRAMMER port (connection port for programming tool) provided with each
BASIC CPU module allows programming for each CPU.
• Programs can be developed and debugged on a personal computer.
• By installing an optional ROM pack, programs and common data can be saved and the
programs in the ROM pack can be run. The ROM pack is useful when performing
program replacement and making many copies of the same program on site.

• On-line real-time processing
- Supports extensive interrupt methods to enable immediate response of a BASIC program to external events.
- Facilitates development of on-line real-time programs.
• Modular program structure
- Can use subprograms.
- Variables, line numbers and labels in the main and individual subprograms independently, thus it simplifies
development and program maintenance, and improving program reusability.
- The main program and subprograms can be developed separately, and assembled together by using the
APPEND command later.
• Combination with sequence programs
- Variables used in a BASIC program can be combined with shared registers by a common variable
statement, thus it facilitates data exchange with sequence CPU module. Synchronization with sequence
CPU modules can also be achieved by using SIGNAL, ON SEQEVT, ENTER and OUTPUT statements.
- Device values in CPU modules can be read and written by using ENTER and OUTPUT statements.
• I/O support
- Can access various communication modules such as serial communication modules, various digital I/O
modules, and various analog I/O modules by using ENTER statements for input and OUTPUT statements
for output.

LObject Ladder
The FA-M3 Programming Tool WideField is a revolutionary application for programming object
ladder succeeding to structured ladder programming and created with new concept.
An object ladder is a new concept of developing programs. The object in which a piece of program
and the related devices are assembled for each functional unit called a block. The blocks are then
assembled together to form the entire ladder program. Each block can thus be functionally
independent, which improves productivity and program maintainability compared to structured
programming*.
An object ladder is highly reusable. When customizing an existing machine control program for a
particular user, the details of each block need not be checked; blocks are simply added or replaced.
*Structured programming. A programming method proposed by
Yokogawa Electric Corporation in 1989, in which an increasingly
complexed ladder program is divided into parts for individual functional
units so that developers can easily understand the program framework,
and improved productivity and program maintainability. As these
advantages became recognized in the 1990's, structured programming
grew rapidly. Other PLC manufacturers rolled out products based on the
same concept, and structured programming is now the de facto standard
in PLCs.

LProgram Component
Blocks and macros are pieces of program and use common devices as their data. Thus,
devices need to be assigned uniquely not to doubly used in different blocks and macros.
By using the concept of local devices in each block and macro, devices can be handled
independently in each block and macro.
Different macros and blocks can have a local device having the same name since
different physical addresses will be assigned to those local devices, thus device conflict
can be avoided.
Independence of Blocks and Macros for Enhancing Drastical Reusability.
Programs and local devices can be handled as sets so that they can be reused easily as
parts.
zAddress Indication

•Local devices and global devices can be used
as different devices.
•When reusing a block, device addresses need
not to be changed.
•When local devices need to be added in a block,
no change to other blocks is needed.

LIndex View
A ladder program is coded as a long strip of diagram, which makes it difficult to grasp the
overall flow.
The entire program structure can be grasped.
You can hide and show each circuit block under the circuit comment (just like expanding
and collapsing the tree) to grasp the entire program structure and go to the corresponding
parts.
Programs written long ago or written by other engineer can be easily modified.

A name suggesting the corresponding action can be assigned to each device to increase
maintainability.
Arbitrary names for individual devices can be used in the programming before the terminal
assignment is decided. The ability to separately determine the logical design and physical
design (i.e., program design and terminal assignment) greatly reduces the engineering
period.
Wiring changes can be accomplished be changing the tag definitions.
Use of tag names helps standardize circuits and enables programs to be reused with ease.

ABOUT
Conventional PLCs require
terminal addresses. The FA-M3 R allows you to write in logical addresses (tag names).
zTag names can be set easily (see the figure below right);
however, even if the tag names have not yet been set ladder
diagrams can be edited using tag names.
ÆEven when the terminal assignment has not yet been
decided, programs can be developed using signal
names.
zTag names should be up to 8 characters long and begin with 2
alphanumeric characters.
