  1. FX3S not responding to HMI.

    Did you try to update GX Developer, which is a part of GX Works2, and to use it for upload/download?
  2. FX3S not responding to HMI.

    altctrdelighted, it is not necessary to create difficulties there where all could be done simply. Use the PLC programming cable, instead of USB.
  3. You did not specify with what PLC are you working... The HOURS instruction is as a tool.
  4. The Structured Text and the Structured Programming are completely different concepts.
  5. FX3S not responding to HMI.

    With this topic you can know, how to get an update versions for any Mitsu soft: http://forums.mrplc.com/index.php?/topic/31180-fx3s-err-light-flashing/#comment-146588
  6. FX3S not responding to HMI.

    The guidance: Connect to the old FX1S, upload its program/parameters/data table to your PC and save the project. Also upload and save the program from HMI. Check the uploaded PLC program for correct compilation. If it's compiled without errors, then go to the item 4, if not, go to the item 3. Find a completely similar device, upload its programs (from PLC and HMI) and compare the uploaded programs with previous uploads. If they are quite equal, then errors of the program, uploaded from your old PLC, can be repaired, if not, then the action was not successful and it is need to find another similar device... Convert and recompile the program for FX3S PLC.  Connect to the new FX3S , upload its program/parameters/data table to your PC and save the project. Download the convered and recompiled project to the FX3S completely (program/parameters/data). Test the correct operation of your device.

    What's with that old FX1S PLC? Did you try to connect with it and to upload its program/data?
  8. Rolling Average / exponential smoothing

    P.S. Also SFTWLP & MOVP might be used.
  9. Rolling Average / exponential smoothing

    For QCPU the WSFLP can be replaced with combination of DSFLP and MOVP instructions.  http://www.automationsystemsandcontrols.net.au/PDF's%20Mitsubishi/Manuals/QPLC/QCPU%20Programming%20Manual%20(Common%20Instruction).pdf pages 59, 422, 
  10. Rolling Average / exponential smoothing

    Now the lib is open)   FB_Rolling_Average.SUL
  11. Rolling Average / exponential smoothing

    It's locked with password?
  12. TOTAL FLOW OR TOTALIZER

    A total flow is calculated as follows: Qn = (Vn + Vn-1)*dT/2 + Qn-1 , where - Qn is a total flow at current measurement; - Qn-1 is a total flow at previous measurement; - Vn is an instantaneous flow at current measurement; - Vn-1 is an instantaneous flow at previous measurement; - n is a number of measurment (starting from 1) - dT is a time interval of measurements. It's a constant.   For example: If V0= 0, V1= 0, V2= 2, V3= 4, V4= 8, V5=8, V6=4 [m3/h] and dT= 0,1s , then Q0= 0, Q1= 0, Q2= 1/36000, Q3= 1/36000 + 3/36000 = 4/36000 =1/9000, Q4= 4/36000 + 6/36000 = 10/36000 =1/3600, Q5= 10/36000 + 8/36000 = 18/36000 =1/2000, Q6= 18/36000 + 6/36000 = 24/36000 =1/1500 [m3]  
  13. Rolling Average / exponential smoothing

    Yes, it could be adapted. Just need to search the instructions with similar fuctioning in Q/L Programming Manual.
  14. Rolling Average / exponential smoothing

    This is library for FX, which you can adapt for Q. FB_Rolling_Average.SUL
  15. Convert 7 digit ascii (hex) to 32 bit Dword (dec)

    Certainly. What prevents you to use DDABIN instruction? Before the conversion, just move the datablock, given from the scanner, into an array of 6 words. Then, using the DDABIN convert the array into 2 integers (DWORD).
  16. Dear wlederer, 1. The PLC manufacturers has an interest in big sales. The structured programming reduce the time for project development and it's comissioning, especially if the project has a huge volume. Thus, the system integrators are able to implement more projects in the same time interval, i.e. they will use more SPS during the same period. Other words, the goal of investment is present for both sides (manufacturer and customer), both will get more money profit in annual. 2. You may ask, why the first item does not work?  The PLC manufacturer managers does not understand anything in PLC programming issues. The developers of programming software tool does not understand anything in it too. Only software engineer may know in what he is really need! That to obtain a good result in programming software development a close feedback from the PLC engineers is necessary. But the first pair is convinced that they are much more clever and coolest than the last. 3. Even if the PLC manufacturer has managed to create a successful development tool, it's not enough for the final effect (to increase the profit). It's need to organize an effective education for its customers, i.e. for the PLC programmers, working for system integrators. But how the manufacturer can do it, if he does not have an own department of automation project development thus own engineers (teachers) does not have an experience of implemention real projects?? In this case such education of wide circle of customers can be provided only with participation of talented PLC programmers, working for system integrators, that are alone learned and tested all possibility of the SW. But what system integrator would like to multiply competitors for himself??   I could share here with items 4, 5 etc. that prevents for Mitsu (and some other manufacturers) to create an excellent programming tool. And for customers does not allow to get and use a good programming tool, to get a good education and knowledge in effective using of new programming products and all their capabilities. But for whom these arguments will be useful?.. *** If you or somebody else there want to feel and understand in what are the benefits of structured programming, I could offer two way. The first is I can share the ready programs, written by me, that it might given a chance to learn and analyze the technique of programming alone. The issue for english speaking people is all comments in these programs are in Russian... The second is a tutoring. This way requires a time and serious efforts by my side. The advantage of this way is that together we will develop a new existing project(s). The drawback is that this way is costly for pupils, because a time of tutor and his nervous is the money.  For a PLC programmer has a meaning to pay from own pocket for this tutoring in case he'd like to rise his level higher and to leave from the current company to get a higher salary. For the employer has a meaning to pay for the tutoring in case he understand that such tutoring will bring him a greater money than he spent. In practice, the first category is not ready to pay, at minimum, due their current salary does not allow to pay for the tutoring, both and they are don't sure that it will allow to find a better job. The second category don't ready to pay, because: 1) they are don't feel and understand a huge difference between seminars and workshops, providing by PLC manufacturer, and a tutoring; 2) they are prefer official certificates by manufacturers in comparision to get a market superiority on which they are making money;3) they are not sure that when they will spend the money for study of the employe, they are not losing the spent money toghether with the employe... Kind regards,
  17. Hi ParaffinPower, Mitsu manufactures products that are quite reliable... in a technicial plane. The issue is a stupid management and bad documentations, a cheesy software. If to say about the management, I know two people (in Europe), which are qualified specialists and good guys. However they are workinkg under a very stupid leadership. I'm very, very angry to Mitsu management for a lot of issues, they created and continues to create. I'd with a great pleasant thrown the Mitsu to a bin, but I spent about 20 years of my life using this equipment.
  18. Heh, Ron_S, It's funny. But for me it is so melancholy....
  19. Dear wlederer, Yes, absolutely. The single thing, I don't understand how I can able to help you to estimate all advantages. It looks very difficult, in particulary if to take into account that my spoken English is not so good(
  20. wlederer, your conclusions are very and very strange. Everything is exactly the opposite.
  21. SCADA for FX3U

    The main thing, which I'm considering as critical, the MAPS doesn't work principally under home version of Windows. That does not allow to estimate preliminary, will it suitable for the current project. This fact has kicked me to find better product, and I found it...

  24. Array of SDT as I/O on FB

    1. It's imposible to answer, not seeing your program. 2. There is not neccessary to transfer an array to the FB. It's easier to define it in GVL and then to access to its elements inside the FB by array index.
  25. Accessing specific bits in a word.

    collinsd70,  INT_TO_BITARR 16 = MOV Dxxxx K4Myyyyy. It's just an IEC interpretation of MELSEC command instruction.
