  1. S5 PC to PLC Cable

    Hello ! I am really sorry for late reply . I have many .... . Any way, I am trying my best to fullfill your needs. The solutions are here. 1) S5_SPS is my home brewed circuit and you can use it reliabily with some precautions. ( a) use a transformer without center_tap, on the supply circuit. ( b) don't make any modifications on supply side. ('cause it requires symetrical +/- 12V.) ( c) the power sources for all of PC, S5_SPS and PLC must be the same. (Use the panel power outlet if available on site) ( d) as there are no isolation between the electronics, you must handle them with care. (But I don't meet any problem till now) 2) RS232_TTY schematic is downloaded from somewhere. (I can't really remember) And I have not tested it till now. Use it at your own risk.

  2. WindowsNT on Pentium 4?

    Yessssss! Very useful answer to reality. I have now solved my problem to install Windows NT on P4. I disabled all the extra features of motherboard (PM8M-V, MSI) including on-board VGA, sound, network etc.. I plugged an old versioned VGA card in PCI slot. A lot of thanks are going to Ken Moore.

  3. SCADA POLL

    I'm a Citect user. But, I know there are alot of SCADA softwares missing in the poll. Is there someone who can list the softs? I think the list of available SCADA softwares should be in HMI&SCADA topic. WBW, Naing
  4. WindowsNT on Pentium 4?

    Well, my HDD is ATA/IDE. Here is my HDD's specification. HITACHI "Desktar" Model: HDS728040PLAT20 Capacity: 41.1GB P/N:0A30216 LBA: 80,418,240 Sectors RPM: 7200 MLC: BA1116 CHS: 16383/16/63 Selector Jumpers for 16 Heads, 15 Heads, 32GB clip, Autospin disable Thanks, Naing
  5. WindowsNT on Pentium 4?

    Yes, I meant that WindowsNT installation was aborted prematurely showing BSOD (blue screen of dead) with many strange codes (00x00000-----bla, bla). I have tried reducing the partition-size to 2.1GB and FAT16. But, it didn't work. Is there something else to take care off?
  6. Dear Experts, My SCADA software, RSView32 v5.0.1 (w/activation code) can only be installed on WindowsNT 4.0. So, I need your help to install WindowsNT 4.0 (SP4) on the Petium 4 (PM8M-V) PC. I tried several times to install it. But, the installation was terminated prematurely. Please help! Yours, Naing
  7. Plc5/3 losing program

    Yes, sure. There are "many of dry joints" on the PCB. But I didn't mean that AB is loosing their QC. According to the machine's enveroment, I had decided to go that way to reach the solution. Btw, my PLC lost sometimes the program when the machine was vibrating in the process, even the power was up. WBW Naing
  8. S7-400 Counter Card problem

    Hi presario2100! You didn't show the card's code and version (6ES7450-xxxxx-xxxx). Is it exactly the same as the old one? If it is not, you need to reconfigure the program on-line. Please try to purchase the tools. WBW, Naing
  9. s5==>s7

    I have the same questions like you. Even I don't have real experiance, I think it will depend on the conversion parameters such as old S5 PLC model and new S7 PLC model. Sometimes you need to modify the FBs, OBs, PBs,....etc,. Atleast, you need to check the converted I/O assignments. (Just only my opinion, lets listen the experts' speech)
  10. Simple programming cable for Mitsubishi FX

    You should reference rajsiyer's attached document.
  11. Plc5/3 losing program

    ==plc5/3, if power is turned off on the machine for several days it loses the program. They have tried several batteries and have also changed the cpu card. Has anyone out there seen this problem before and have any ideas how to fix it?
  12. Should we have an AC Drives Secrtion ?

    I voted "YES" because I know all of us have met the industrial drives at some time and some where. The industrial drives are also the part of the automation. We can't avoid to face with them when we are trying to diaganose the malfuntioned system. PS. The name should be "Industrial Drives" to be included AC/DC/Servo and Stepper Drives.
  13. Programmable terminals (HMI)

    Hi sandytay, It is hard to say which is the best. Decision is mead based on price, compactibility to the system, getting technical support, etc.,. If you prefer OMRON HMI, you can get many of docs by googling the net.
  14. Timers, counters

    Hi sandytay, There are tons of industrial timers and counters in many catagories. First, you should specify your need expressing type, range , control methods etc.,.
  15. F series PLC

    Hi yammipoh, Have you ever tried it before? I have used this method on the OMRON C200 CPU. I think you should read the EEPROM directly from the GXDeveloper's Tools>Transfer ROM menu. Or may be I am wrong this time. Good luck!
