  1. PID control advice?

    Base on your diagram ,it is possible but not quite accurate, since 10 minutes is long time  feedback. If "NO" other issue why not bring your acid dose closer to Alkaline dose. to reduce the response time.
  2. S7-1214C All LED Blinking

    Is that a brand new CPU, no previous program installed? if yes then the LEDs are normal, once you download the program and you meet all conditions you will only see the green status LED only. Your problem is that you are not establishing the network connections. Please check your firewall settings and antivirus settings. check also your LAN connections, your IP address from the PC and PLC should not be the same. in your picture the RX /Tx should be blinking, indicating a data signal exchange. try to ping also, if the CPU will response, then 100% you can download the new program.
  3. Need some help about S7-200 smart PLC

    a big possibility the file has been corrupted. try to open another file (program) and see if it can open.
  4. MicroWIN, problem: "Class not registered"

    I'm using virtual machine or VMware in that case...
  5. MicroWIN, problem: "Class not registered"

     Classes are registered during the installation of the software in the registry. If you get an error code " class not registered " there maybe something wrong in the installation or you may have installed incompatible software.

    Hi, check this out... https://www.steute.com/en/wireless/products/wireless-inductive-sensors.html https://www.steute.com/en/wireless/products/wireless-universal-transmitters/rf-io.pdf
  8. thank you, got it.   now i need to replace my math instruction to + instead of +B. 
  9. Hello Omron programmers, have a nice day to you all. I just need your help in this, i hope you have explanation.  I added a few sequence to the machine with compare instruction D2255 and D2259 as memory data. I really wonder what’s going on. D2255 a decimal value of 9, when it transferred to compared instruction it’s 9, but when D2255 become 10 or above, when it transferred to compared instruction it will become 16 or above, there is an additional of 6 to the decimal value when it more than 9. I attached the photos of it for more details. Can somebody please help me? Thank you.            
  10. High Speed Counter Problem

    hi, try to replace your encoder. i don't know what's exactly the history of your machine. if that's an old encoder and working before, a big possibility that is defective, or connections and cable issue.  if your encoder is new and not exactly the same spec as the original one , then try to check again its specification and the hardware configuration in the plc. You might use different plc, but in  s7-1200 sometimes you might adjust the input filters, or sometimes i might use word math instruction to create some factors for specific application or just to meet a certain requirement. 
  11. Siemes CPU216 2BD23-0XBD Issue

    Hi, you input 1800 value direct from microwin to the cpu not from HMI, i am right? i wonder what is the status of your CPU. is there any alarm on the CPU?
  12. Siemens S7-1200 1211C, should I buy it?

    This CPU is great for practice. it package also with Analog input i think, just add Signal Board (SB) for additional analog output. That would be cheaper. 
  13. simulator for S7-200 Siemens Simatic PLC

      Shehza2002, the simulator of s7 200 is a third party software not developed by siemens. the simulator key was already given above (6596), and you can download it legally for free in CNET and other website.  I recommend also the FACTORY IO 3D simulator. it's compatible also to a many brand of PLC's. https://factoryio.com/
  14. By using Prosave you can't edit the program and you can only downloaded it to the same model of HMI, unlike back up transfer you can edit the program and you can also change the device. You can only do back up transfer if the previous programmer enable the back up transfer option the last time he downloaded the program, if not then you can only use Prosave. This is what i experience in wincc 2008 flex.
  15. HELP! Wiring 1214C DC/DC/DC CPU

    Hello, the Photo is a little bit dark,  I can't read the marking. anyway Please try to check the attached picture, it might help you.
  16. Downgrade Firmware HMI TP1200 Comfort

      Just try this perhaps it will work, you have similar problem in one of my colleague. This procedure solve his problem. - Open the Control Panel of the computer - Check in the top right corner if "viewed as" (or similar) is set to small or large icons (not category) - Open "Set PG/PC-Interface (32-Bit)" - In the Drop-Down menu on top, check that the access point is set to S7ONLINE - In the list below are all network interfaces of the computer listed. Search there for the ethernet-adapter, with which the panel is connected to the PC and select it. CAUTION, there are 3 entries for the Ethernet-Interface, select the one that ends with ".TCPIP.1" (NOT .TCPIP.Auto.1) - Hit ok ProSave: - Set on the general tab the connection to Ethernet or PN/IE - Set on the general tab an IP-adress for the panel, which is in the same subnet then the computer - In the OS Update tab, check the box for reset to factory settings, enter the MAC adress of the panel and click on update (panel should be started before) If it still doesn't work now, disable all firewalls and anti virus softwares, because some of these softwares don't let neccessary packages pass, that are needed for establishing the connection.      
  17. array and string

    String is very useful if you want to send character from PLC to be display to the HMI.   In small application you don’t need an array, but for larger application array is great option, especially when you want represent multiples values in single variables.  Example in data block an array of [1..30] real - Temperature.  So instead of writing individually to access all those 30 temperature value, just do it in an array to save time, space and easy to remember during your programming.
  18. S7 300 Profibus fault

    Is there any FM card or any other module in the slot under the station IM 153?  In my experience. example the FM  card will alarm due to the encoder was faulty. Your IM 153 will goes to System fault or SF alarm, and that will appeared to your diagnostic buffer. So try to consider also the module under your IM 153, maybe one of those module in the station cause the alarm. 
  19. FX3sa-20MR

    Hello everyone, Have a nice day to all. We just received a small machine from china, and definitely we done a lot of modification to add  safety and other sequence, to adapt this machine to the existing line. I'm familiar with siemens and omron, and this is my first time for mitsubishi PLC. FX3sA-20MR, can somebody pls. help me what software do i need to download and programming cable to communicate with the PLC. Thank you in advance...
  20. from the software of your HMI try to search if the s7-300 plc is available. i mean try to check the compatibility first. what model of delta HMI you have and the model of s7-300?  we can use profibus or MPI protocol or even profinet.  
  21. S7 300 Profibus fault

    You need seimens step 7 software and  try to troubleshoot online.  go to the diagnostic buffer, and it will display which module or any that causing the problem. or go to the hardware configuration and online, you can see from there the modules condition, the module failed to communicate will be mark with x. is your CPU SF led is ON? what is the condition of the CPU? any red led is on. i mean the BF? SF?. try to secure the software, it will not take time troubleshooting if you have the software. 
  22. Siemens SIMATIC S7-1200 connection problems

    Hello DRQ, First you need to set your PC IP address.  then you can follow this video. https://www.youtube.com/watch?v=9UkMBaDn_ec https://www.youtube.com/watch?v=-Au6m45GIvA  
  23. wincc flexible

    Hello, If you have this type of HMI; SIMATIC HMI KTP1000 BASIC COLOR PN (6AV6647-0AF11-3AX0). You can configure it from  WINCC FLEXIBLE 2008 SP2. Definitely you can find this software for free in the net  if you are a resourceful enough.     
  24. wincc flexible

    hello PV550, You can't view the tag screen only or the whole project you can't open? Because in wincc flexible, base on my experience. we can't open the project if we use prosave to back up the program, we can only download them back to the same model of HMI. if the previous programmer is kind enough to enable the back up transfer during the last time he downloaded the program, then that is the only way i know to do the "back up transfer" and edit the program.
  25. wincc flexible

    I apologize for my sentence Crossbow. this is really what i mean for Donne: https://support.industry.siemens.com/cs/document/38612895/service-pack-2-for-wincc-flexible-2008?dti=0&lc=en-US. you can update your wincc for free. i already update mined and its working now. if you have 64bit OS, maybe wincc flexible SP3 will do. take it from here: https://support.industry.siemens.com/cs/document/58860033/update-for-wincc-flexible-2008-service-pack-3?dti=0&lc=en-WW
