A brief introduction
of fanuc ladder series
Often see a number of internet users looking for
something fanuc ladder, for example, how to use and install, how to write fanuc
the eprom, how to look at the ladder diagram eprom. This profile is to do a
presentation of these elements. (Note: plc in fanuc system has been known as
the pmc)
Fanuc PMC programming software, currently there are three versions on computer,
namely fapt ladder (slang is ladder1), fapt ladder ii, fapt ladder iii. In 1980
there is a special programming device is called fanuc pe and fanuc pg. As
follows:

The dimension and outline of fanuc pe and pg as like as Radio Shack¡¯s TRS-80
computer.
pe is a text editor, pe and pg have apt automatic programming function (apt
program is the predecessor of cam) and fanuc pmc ladder function. System p
modle g referred to as (pg) is the graphic of the first letter of graphics, so
the p-g has color and graphics. fanuc pe, pg support ladder of fanuc
1,2,3,5,6,7,9,10,11,12 cnc systems.
In this paper, only three versions of the computer to make a brief
introduction.
1. Fapt ladder: (commonly known as the ladder 1)
Boot menu and version number as follows:

This is a software to work under dos.
Fanuc pmc support include as follows:

This version of the software is mainly used fanuc 0
2. Fapt ladder ii
Boot menu and version number as follows:

This software is working under dos, pmc support is as follows:

The inside another menu and function is most likely ladder 1.
This version is mainly used for fanuc power mate 0,15,16,18.
3. Fapt ladder iii
The boot menu of the software is as follows:

The software work in windows. Now it has some different versions.
Pmc support are as follows:

Ladder iii currently supports all of the i series systems.
A. DOS version of the ladder (including the ladder 1
and 2) the software how to install windows xp.
Many places as a result of xp from nt, and nt in 2000 under the estimated
method is similar. Xp popularity as a result of comparison, I will do a test.
The following will describe the results of the experiment. As you know, if
there config.sys under dos if not the following statement: device = c: \ dos \
ansi.sys . Ladder will be displayed after the software garbled. In fact, under
xp to solve this problem as long as the ladder software can be used. Config.sys
in xp have been renamed under the config.nt, its path is as follows: c: \
windows \ system32 \ config.nt. Select the file, right-click the mouse by
selecting the documents to open the document. Can choose to open WordPad. Press
the map after adding ansi.sys. Modify the location of the tail in the document.
After completed the preservation config.nt Add ansi.sys work. Xp and then click
fladder.exe directly or can ladder.bat normal use. Modify it is quite simple!

Another modification: Ladder ii in the setup under xp installation, option.cnf will not be automatically decompressed. It will appear on the 'option.cnf' alarm. This file in disk5 \ fladder\ path, the file name is option.cn_, this is a compressed file. After extracting the full name of the document is option.cnf. As a result .cnf file extension in xp for being the default is: "Speed Dial" program. Therefore, under the xp will be installed to prevent this process. Disk1 inside can be used to extract disk1\ unpack.exe (I did not test this procedure) or use dos of 'expand' command to extract to (I did the experiment). Then after copy option.cnf under the installation path of ladder ii.
B. How do you copy fanuc pmc the eprom.
Copy eprom the basic principle is :
1. The right to choose correct types (in general can also be compatible). For
example: intel 27256, hitachi 27256 can be used interchangeable.
Selecting types on the burn software: If do not have the same ic chip¡¯s name and
the chip, as long as the programming voltage is right, we can use. For example:
Select the software to read and write Hitachi27256 chip can also intel27256.
The same principle as the reading and writing.
Eprom chip choice: as long as the issue of 27256 printed on a
chip would be small. Many of the current 27,256 pieces are second hand, if the
writing can not successful. You can use ultraviolet irradiation to erase again.
The quality of good chips can be cleared away five minutes. Therefore, do not
use erasable eprom when the time is too long. Some people see up to 20 minutes
to erase. This will affect the number of normal write the eprom.
2. To select correct programming write voltage:if you don¡¯t know the eprom pgm voltage,beginning
you can select lower voltage
3. Read eprom has not dangerous. Reading the chip is generally the original
chip of cnc machine. Reading the chip is only used chip supply vlatage +5v ,
the parameter in various types of chips are the same.
4. Write chips, the chips were generally written by the user bought the chip
space, even if the fire does not matter. So do not stress. If you can according item 1,2 it should be ok.
Normally EPROM write voltage is +12 v or +21 v.
According to this principle, any cnc system eprom can be copy by commercial
eprom writer/reader.
5. Fanuc dedicated eprom reader
.
Fanuc picture of the reader. It is said that expensive.
The reader to 100v voltage, it also requires the use of
transformers to use 220/100v. Reader to connect the computer to start the
ladder can choose to read and write on the eprom. Operation of this reader,
there was no choice eprom programming model and the choice of voltage. Write
the general programming voltage of +12 v, so long as the purchase of a suitable
write voltage can be a eprom chip.
C. how to read and write eprom the pmc
Read eprom: 1. only for copy 2.to look inside ladder diagram.
How to connecte:PC to connect fanuc writer/writer
Ladder software read rom1 and rom2 and then to
produce .#ex file for discompile.
rom1, rom2 ---->. # ex
And then press f4 softkey to do discompile,next
step press edit key you can look ladder diagram.
Write eprom: after discompile the ladder 1 produce .#ex file
which one is used for writing eprom. The.#ex file length is 75360 bytes. Ladder 1
software write eprom by fanuc eprom writer. Every eprom is 32768 bytes.
. # ex -> rom1, rom2
Please note here. 32768 x 2 is not the same as 75360.
Therefore, the separation process of this document and the general single-chip,
microprocessors different separation systems. Is not the odd-numbered addresses
and even addresses a simple split.
D third-party
fanuc eprom converter
The converter software is designed to be. # Ex -> rom1,
rom2 and rom1, rom2 ->. # Ex of course directly through the software realization.
Through this software, in pmc eprom to read and write can be used on any commercial
eprom reader without the need to buy a dedicated reader fanuc. Detailed operation
of the website can view www.cncb3h.com. The converter software can help repair
and retrofit. More
