For REDHAT7.2, it's the default is to open a firewall, so the external IP has refused to visit it, so that other network equipment can not access it, that is, it can not be NFS mount, can not download it from the TFTP can not telnet, ftp it, and so on. After the installation of the network, therefore, should immediately turn off the firewall. Operation as follows:
run the setup, select Firewall configuration, select No firewall. And then on to a menu to choose System services, and remove ipchains two iptables service. Finally, from the setup.

In fact, the installation REDHAT7.2 / 3, the Custom option requires custom installation, which is requested by a select No Firewall, this is the case, after the start, you do not need to setup the implementation of the firewall settings. There are, REDHAT here to have a BUG, that is, no matter Firewall configuration into the last time you choose, every time when it once again into the show High, this is REDHAT shown BUG, in fact firewall has been closed.

in view of the current issue of the package using uClinux as its root file ROMFS System, so most of the directory can not be written. Only / var, / tmp is a RAM disc can be written, but the board inside a brown-out on the contents of the lost, it can only be used as a temporary file, not the permanent preservation of data, such as profiles, and so on. Tell us about the following several FLASH on the way to save configuration:

1. for simple, small profile, and so on, but not very frequent (for example, Wrote one minute 10) to write and direct their own in the free FLASH Department (for example, the second film on FLASH) to draw a region in order to write their own definition of the way, and board automatically read out. Hua Heng provided such a sample code, that is, the user / memtools /, the details of the second chapter in the manual "FLASH sector to preserve IP address" section. To make such a big advantage is that users control the extent of the largest and most flexible form, can be kept by the custom data, you can not file the form. The following are several ways to preserve the form of document requests and can not deal with custom data preservation.

2. For more profile, the general RAM are written on the first day, and then choose to save, one-time write a few FLASH sector. Flatfsd can then use the software, which required the use of the core with support, that is, in blkmem.c designated for preservation of data in several sectors of the start / end address. In this way can not meet very often write.

3. Frequently compared to the preservation of data, it is necessary to establish additional board in the log-file system JFFS/JFFS2, or simply used to replace JFFS/JFFS2 for ROMFS root file system. This directory is the board can be written, just as hard, do not need additional tools to be responsible for the data will be written into the FLASH. JFFS is supported by the 2.0.38 kernel, it does not support JFFS2, JFFS2 was to support the 2.4 kernel, it adopted a mature and stable technology MTD, the JFFS than stability. Both the file system in uClinux does not support the realization of the complex, but it is also the practical need for some additional work, such as the programming tool with generating new image.bin compiler, because the real product of the software is allowed to each After the start times are also carried out many of the manual, for example, the file system to load, and so on, the factory programming board must first be completed, but not many points but also programming and so on, these are rather complicated, and there is no Programming tools, source code can not be completed. Hua Heng JFFS/JFFS2 to provide the entire software technology.

Such as LINUX is not aware of any 8M this address, this OS in the allocation of memory when not to use these address space, which is equivalent to steal memory from the OS where to use their own.

In the process, there is a problem of competence, that is, the host board mount hard disk, NFS mount this operation is not the default to the root of the implementation of the authority, so it does not have permission to board the implementation of the host program on your hard disk, At this time it is necessary to host in the run chmod 777 app, which app for the application executable file name. In fact, this phenomenon is still relatively easy for developers to solve, because when the implementation of the application, minicom will be error, permision denied, or unknown error 4. But for some the situation is not always so easy to see that the authority is the issue:

such as: WEB management software debugging code cgi, we place the host / cgi-bin / through the NFS mount to the board of the CGI work in the directory / home / httpd / cgi-bin /, this time through the implementation of the IE browser, CGI Operation, the error would be 403, there is also a question of authority, that is, the CGI directory can be asked to write their work, it is necessary at this time in the host run: chmod 777 / cgi-bin, this time, the browser will be able to immediately Work.

This problem is often due to the customer is not in the implementation of the uClinux directory make for a unified compiler, but the application directly to the implementation of the directory due to make. This is due to uClinux / user / application under each of the Makefile to use a lot of macros, included in the CC and so on, these macros are unified under uClinux in a directory defined in the document, if the user directly to the user / Under The application directory implementation of the make, these macros will not be able to access uClinux to set the value, but automatic use of the default PC LINUX system, such as the CC if the user does not specify, the default is gcc, so there will be no application to use m68k-elf-gcc compiler, but PC LINUX under the gcc compiler, so that made up the executable file on the board, of course, can not be implemented.

with the microprocessor production, low cost, compact structure of the CPU and peripherals connected to provide a framework for stable and reliable hardware, embedded systems development restrictions on the outstanding performance bottlenecks in the software. Although the late 1980s and started a number of embedded operating system, there are relatively well-known Vxwork, pSOS, Neculeus and Windows CE. But these are specific operating system product commercialization, the high price of many low-end products that discourage small companies; In addition, closed source code is also a major constraint on the developer's enthusiasm. In addition, the combination of domestic situation, the current state of their own operating system support for an open-source LINUX promotion provided broad prospects for development. Also, on the upper application developers, embedded systems is needed is a set of highly concise and friendly interface, reliable, widely used and easy to develop, multi-tasking, and low-cost operating system. In the near future, from refrigerators to the radio will be built-in processor. Because of the openness of Linux, many people think Linux is suitable for the majority of Internet equipment. They believe that Linux can support different equipment, to support different configurations. Linux vendor of low-cost and even-handed, soon to become the equipment used for a variety of operating systems. Today, the industry has reached a consensus: that is, embedded linux is the general trend and its huge market potential and business opportunities will certainly brewing to attract a large number of manufacturers to enter this field.
embedded operating systems are Palm OS, Windows CE, EPOC, LinuxCE, QNX, ECOS, LYNX, high-end embedded systems require a number of high-level functions, such as the graphical user interface and network support. Many high-end RTOS suppliers have to provide these functions, but the price is very high-end, it is generally difficult to accept. Microsoft's Windows CE also has such features, does not have the most embedded systems require real-time performance, and are difficult to transplant, has also been said to want to use the DOS-based independent third-party tools to put together a system, but such efforts will be In vain. What is needed is a less mature and high-end embedded systems to provide the necessary characteristics of the operating system, embedded Linux operating system to low-cost, powerful and easy-to-transplant and is widely used, has become a rising force, so many Businesses have turned to embedded linux.
Linux for embedded operating system provides a very attractive option, which is similar to Unix and to the core-based, full memory protection, the process of multi-multi-tasking operating system. To support a wide range of computer hardware, including X86, Alpha, Sparc, MIPS, PPC, ARM, NEC, MOTOROLA, etc. Most of the existing chips. All open-source program, anyone can modify and in the GNU General Public License (GNU General Public License) under the issue, so that developers can customize the operating system, no longer have to worry about operating systems like MS windows in the "back door "The threat. At the same time, because of the GPL control, the development of all the things most compatible with each other, not to split the road. Linux users who encounter problems to the Internet through the Internet hundreds of thousands of Linux developers to ask, which makes the most difficult problems can be solved. Linux with Unix users are familiar with the sound development tools, almost all of the Unix system software has been ported to the Linux on. Linux also provides a powerful network functions, there are a variety of optional window manager (X windows). Its strong language compiler gcc, g, and so on can also be easily. Not only improve the maturity and ease of use.

  choose linux reasons
  can be applied to a variety of hardware platforms. Linux has been ported to a variety of hardware platforms, which is subject to cost, time-bound items research and development is very attractive. Prototype can be developed in the standard platform and then migrate to specific hardware, software and hardware to speed up the development process.
  Linux can be configured to not require any permit or business relationship.
  it is free, source code available. This is the most attractive. There is no doubt that this will save a lot of development costs.
  its own built-in support network.
  Linux's highly modular so very easy to add components.
  Linux on the desktop to the success, so that we can see linux embedded in the system brilliant prospects.

2. Go beyond the "North and South Bridges" structure, the introduction of a new "speed up the structure of the center". Intel810 still use a i82810 (MCH) and a i82801AA (ICH), but their use twice the bus bandwidth bus Dedicated bus bandwidth, bandwidth to reach 266MHz. 82810 integrated graphics and memory control functions, 82801AA integration of the peripheral control functions.

3. Again The definition of the structure of the bus so that the chipset's internal processing speed peripherals and data exchange with the greater capacity and peripherals can share 82,801 Bus 266MHz bandwidth.

Intel810 and Intel815 comparison
1. Intel 815 full advantage of the 810 inherited, and further optimization.

2. VGA: in the 810 on the basis of the integrated AGP features (i752 AGP4x), in addition to a high standard graphics card or memory card. (I752 can be automatically shielded)

3. ATA: 810 ----- ATA66; 815 ------- ATA100;

4. RAM: 810 ----- Upto 256M Dimm; 815 ------ Upto 512M Dimm;

5. PCI: 810 ------ 4xPCI; 815 ------- 6xPCI;

6. USB: 810 ------ 2xUSB; 815 ------ 4xUSB;

7. Audio: 810 ------ 2xChannel; 815 ------ 6xChannel;

8. LAN: Intel 815 built-in LAN controller integrated
from the 815 and 810 comparison, the 815's ability to drive significantly improved, indicating 82801BA (ICH2) over the functions of 82801AA (ICH) stronger; for gigabit network and high-speed data, is clearly more than 815 810 better position to deal with.

in NT4 install SCSI hard drive, there are two circumstances: 1. SCSI system to be installed on the hard disk 2. the system has been installed, coupled with the need for a SCSI hard drive.

1. First of all, need to do a disk drive. Rocky3782EVS using Symbios53c1010-33's SCSI chipsets, and its accompanying CD-ROM drive in the middle. The path is as follows:
\ SCSI \ Symbios \ 53c1010-33, this is a compression program, or Winzip be WinBar decompression after use (which can extract the hard drive or floppy disk). Decompression after the path Keep in mind that (his best Specify a directory). Decompression after the driver for a number of operating systems, NT directory selection, will Kaoru driver floppy disk, make a disk drive.

2. In the first case to be installed at the WinNT Setup screen to install blue screen when the switch by F6 keys until a special screen installed equipment in the conduct of the SCSI device is installed, do a good job to insert the disk drive, NT will recognize that SCSI models of controllers, according to<enter>continue, with the following general steps to install; otherwise the procedure will be prompted to install the "File system couldn't loading "can not continue the installation.

3. The second step in the installation of the following circumstances:
boot Self-test, detected two SCSI controller (onboard), if the hard disk has been put up at this time, it should be hard to detect.
suggested that the NT patch together.
into the system<My Computer> \ <Control Panel> \ <SCSI Adapter> \ <Drivers> \ <Add> \ <From to Disk>, insert the disk drive (or directly to the driver to extract the hard disk) to start Install the driver. After the completion of the installation process will be prompted to restart.
to restart the system after the<Disk Manager>found more than a hard disk, partition and format it to use this after a SCSI hard drive.

1. In the new version of Protool / pro CD-ROM, in the images \ TP170A \ V5-2-SP2 find Ptupdate.exe documents, running the file, it will pop a "net-ptupdate" window. In the menu "file"? "Setting" a good set of communication interfaces, such as coml.

Win9x drivers for the next decompression software, installed in the display driver when you want to Specify the correct path to the document. Right after installation, \ display \ settings \ high-level dialog box, multi-page menu should appear in the menu to set up TV-OUT functionality

that this is only a reference, based on a random manual and CD-ROM installation.

above, according to this procedure, we know that the control of the use of the word, but also know that the stepper motor cycle with the red pulse of the number of storage locations (for Q0.0 is SMW68 and SMD72). Of course, VW100 and VD102 different data, the stepper motor speed and turning circle is not the same as the number.
that there is a need to note: M0.0-on --- PLC capture the rising edge of the pulse output after the launch, would like to stop, only to change ports of the pulse control word, and then start to PLS, the procedure is as follows:

2. High-speed counting function.
Siemens S7-200 series PLC with a high-speed counting functions; give an example to talk about the use of high-speed counting, we have adopted a common motor drive to screw rotation, we would like to turn control of the distance, how to solve this problem? Then we will be able to motor the other end with one encoder connected to the electrical circuit, the encoder also turn around the same time, according to the specifications of different pulses. Of course, these pulses of high frequency, PLC can not be used to counter rising edge of the common pulse of these can only be realized through a high-speed counting function.
start high-speed counting function, but also have control of the word

HSCO HSC1 description of the
SM37.0 SM47.0 effective reduction level control high-0 = Effective, effective 1 = low
SM37.1 SM47.1 start an effective level control at 0 = high effective, 1 = low effective
SM37.2 SM47.2 orthogonal counter rate option 0 = 4X count rate , 1 = 1X count rate
SM37.3 SM47.3 control the direction of the count by count bit = 0, 1 = count is
SM37.4 SM47.4 to count into the HSC in the direction of 0 = no update, update = 1 count direction
SM37.5 SM47.5 to the HSC into the preset value of 0 = do not update 1 Update = preset value
SM37.6 SM47.6 write to the HSC in the current value of 0 = no update, update the current value of 1 =
SM37.7 SM47.7 HSC allowed 0 = prohibit HSC, 1 = allow HSC

in the light of the above table, we have chosen to HSC1 high-speed counter, for the control of the word SMB47, now we have to start high-speed counter HSC1, by choice for the count, count to update the direction of re-setting the value of the current update: this is the case, HSC1 control of the high start-up : 11111000 into a band of 16 to F8, will start the counter when the current value stored in the SMD48, will be stored in place SMD52, specific procedures are as follows:

Similarly, if the counter in the work of the state would like to stop the counter, it must change its control of the word, the HSC start the following specific procedures:



3. PID control loop.
Siemens S7-200 series PLC's quite simple PID control, through micro / win software, a program guide, in accordance with tips, step-by-step implementation of the requirements you can attribute the PID control, PID here to talk about the three The significance of the specific parameters: P gain for the item, P greater effect on the response to the rapid adjustment in the flow valve: Set for 50% of the traffic, when traffic is currently close to 50%, more than just that if the great value of P, Then the flow valve will be shut down immediately, rather than in the control of a region. This is caused by too much of the gain. In the process of adjustment should be first to adjust the value of P would be more appropriate, then I adjust the value of its points, in the loop controller to control the current value and set value equal to the scope of bias. D for the differential, the main role is to be avoided given the value of the differential effects caused by the transition.
at the scene of the PID parameters of the adjustment process, for Siemens S7 PLC--200 my proposal is different in the control phase, a different group of PID parameters, specifically, when the current distance between the larger settings, consider using a larger P value PID parameters, if the current value Fast close to the range of settings, using a P value smaller PID parameters.
