  1. Are you asking about the firmware updates? No, this is not widespread in the USA. Are you asking about the use of RedLiion? Yes, they are used frequently here in the USA. Especially when you need to move data between hardware platforms. I don't think there's any equal for this functionality. The translation is automatic. Connect any two hardware platforms and the Red Lion will happily move data bi-directionally all day long without any complaint. Most hardware drivers are included.

    You can download the hardware manual from this link: https://support.industry.siemens.com/cs/document/8776697/simatic-tdc-simatic-tdc-hardware?dti=0&pnid=14307&lc=en-WW.
  3. Not to mention the free HMI firmware upgrades that keep their performance competitive.

    The first link I found is here: http://products.mechatrolink.org/en/product/detail/id=238. The controller is identified as MECHATROLINK Spec M-II. Clicking the "PDF" link on this page takes you to here: http://products.mechatrolink.org/direct/page/generatePDF/?path=%2Fen%2Ftopics_detail1%2Fid%3D238&orientation=portrait&file_nm=catalog_238.pdf&disp=inline&margin=0&no_cache=1.  Clicking the  "DOWNLOAD" button takes you here: http://www.mechatrolink.org/en/download/index.html. From this page you can click "Technicl Document"  and find this page: http://www.mechatrolink.org/en/download/manual.html. Be sure to select only documents related to the "M-II" series. There is also a "Software" button which takes you here: http://www.mechatrolink.org/en/download/software.html. However, only "M-III" related software is presented. The device MFR is identified as ESA/GV. Searching for this will take you to this site: http://www.esautomotion.com/home/main/ABOUT-US where you can see telephone and fax numbers for contacting the controller MFR.

    Have you contacted your Siemens representative?
  6. what's the advantage of installing genuine software?

    The obvious reasons to use genuine software have been well enumerated. Cracked software might seem attractive but think of what payloads might be attached. Key trackers, data theft, etc. I don't think the risk is worth it. If I remember correctly, this is how Stuxnet got started. It was incorporated into a crack package that ended up being distributed and installed all over the M.E. and Eastern Europe. My final answer is: don't.
  7. Turning CW and CCw after a delay

    I cannot think of any application where you would want to logically start/run a motor without any logical means to stop it. However, if you are so determined then press the PB once to start the motor. Then disconnect the PB from the PLC. The state of Y2 can also be directly manipulated while online in the software. If you choose to do this then there is no need for the first rung of the logic.

    What is your application? If it is only a home use or learning exercise then I would consider using a Raspberry Pi loaded with CoDesys.
  9. I just recently began using ProjectLibre, which is an open source software. You can download it here: https://sourceforge.net/projects/projectlibre/. My decision to use this software: 1. It isn't Microsoft! 2. It is open source. 3. It will import Microsoft Project files (my primary reason - oh, you thought it was reason number 1? LOL.) After using this software now for a few weeks, I like it. If you have ever used Microsoft Project then you should be able to use this software.
  10. SIEMENS S7 200

    I think I understand what you are trying to accomplish: 1. Turn on a buzzer output for 3 seconds when a PB is pressed; buzzer must continue to sound for the full 3 second period even if the PB is released before the timeout period (3s). 2. Re-trigger the buzzer timer for another 3 seconds if the PB is released and pressed before the initial 3 second period has timed out. The solution is not readily seen because normally one would think that the trigger/re-trigger logic would apply only to the timer. This is not possible because an extended pulse timer cannot be re-triggered until it has timed out. A standard TON will not work because releasing the input PB before the timer has timed out will cause an immediate reset of the timer and the buzzer will turn off. However, a solution is possible: use a re-triggerable timer (TON) but latch the buzzer output directly from the PB press. Test the logic below. I think it will do what you wish. I don't have a 224 CPU to test. Let me know if this is what you are trying to do. EDIT 5 JULY 2019: I just tested this in the simulator. It works. Change the timer preset (PT) value to  300.
  11. Remote connection using eWon

    I've never used eWon but isn't that a Chinese product that connects to Chinese servers? Given the uncertainty of their security, I would suggest using Siemens Sinema.
  12. S7 200 SEG INSTRUCTION

    Analysis: the integer value stored in VB50 (decimal "1") is sent to the 7-segment display (QB5) when bits M0.3 AND M17.1 are both true (high, ON, 1). The 7-segment display must see segments b and c both equal 1; all other segments must equal 0. The S7-200 manual (p325) shows the relationship between the integer value to be displayed and the corresponding segments that must be ON for the correct value to be seen on the 7-segment display. The 7 segments are ordered from "a" to "-", with segment "a" being the LSB of the byte and "-" being the MSB of the byte. In the network example you provided, only integers 1, 2, 3, 4, and 0 are displayed on the 7-segment display. These integer values can be directly converted to a decimal value that will turn on the corresponding segments of the 7-segment display. The resulting code is shown below. It is a direct replacement of your network 76 without inventing a module to act as the "SEG" instruction. Nice, quick, simple, and easy. Just what the doctor ordered! :) Edit 18 June 2019: The absence of the "SEG" instruction for the 12## series CPUs is not due to the TIA Portal programming software. Rather it is because of the CPU (hardware) you are working with. The "SEG" instruction is available in TIA Portal when working with 15## and 3## series CPUs. I suspect the instruction is also available for the 4## series CPUs but I cannot confirm this because I don't have any current projects in TIA Portal that use this series of hardware.  The TIA Portal software only allows access to instructions compatible with the hardware you are programming.  
  13. Controlling Cylinder Stroke Length

    1. How is the cylinder actuated: pneumatic, hydraulic, electrically driven? 2. How is position being determined?
  14. How to replace a safety output card (1734-OB8S)?

    What makes you suspect the card is defective?
  15. problem with keyence

    If the program has been set to read protect you will not be able to upload the program from the CPU into the KV LadderBuilder software. I seem to remember, however, that you can still go onlline and monitor. It's been a long time since I've dabbled with the Keyence KV series and I don't have one handy with which to test my recollection. I've never used the Keyence Backup Tool software so I can't help you in any way with that. If you have hardcopy (printout) of the PLC program, search through it for the MEMSW instruction. This is the instruction that enables/disables read and write protection of the PLC program (and a number of other things, also). This instruction is detailed in volume three of the "User's Manual". The discussion begins on page 3-92. If you do not have a manual it is available from the dowload section of this site.
