  1. How to adjust the resolution of a timer on FB

    The time base is dependant on the timer number,  
  2. Corrupt program?? GX works2

    I find that this issue occurs if the USB stick is removed without first using Windows to shutdown the stick and wait for it to tell you it is safe to remove it, if you just pull it out after use then when plugged back in any PC or laptop, Windows reports there is an error with the stick and requests you 'fix it', Just ignore the message and carry on, It's just Windows nanny operating system kicking in Steve
  3. MOV H400 K4M60? Hexadecimal

    The K4 in the instruction represents 4 nybbles (group of 4 bits = nybble) therefore K4 signifys 16 bits The instruction is moving Hex 10 into M60 to M75, (K4M60), as the binary pattern of hex 10 is 0000000000010000 then M64 becomes true.  
  4. Tools - Options - Online change and uncheck 'Execute online change by complie'   Steve
  5. fx3uc-64mt/d

    It would appear that it depends which polarity the COM is connected to as to wether the inputs source or sink examine the diagrams closely with regards to the COM terminals.
  6. Hi all, Just been given a task of modifiying the program in a Pacdrive C400 controller, (a new one on me). According to Google, the original manufacturer was a German Company ELAU, who have subsequently been obtained by Schneider. It would appear the programming software was EPAS-4, but there is no reference to this on the Schneider website and I can't find any definative answer to the programming package I need to obtain to be able to view/modify the program. Any info would be appreciated. Steve
  7. Pacdrive C400

    Thanks for that, I have dug deeper and found that the current software is probably Schneiders EcoStruxure Machine Expert V2.0 LogicBuilder. There is a 42 day free trial (Rockwell please note), so have downloaded and installed (2.5hrs) to check out. Steve
  8.   This should help, Schnieder info
  9. FX3U-4AD SCALING

    Welcome, As a start I would check out the  Analogue Manual Section B there is a mass of info along with a practical programming example to get your teeth into.   Steve
  10. Check this website for info, appears to be just a USB printer setup. https://www.se.com/in/en/faqs/FA346456/
  11. Timer IC

    you will have to explain further what you mean by the term 'IC' what do you refer to when you say IC
  12. Timer IC

    assuming you mean a timer intergrated circuit a simple well documented unit would be a 555 timer ic, for use with a minimal number of discrete components
  13. You can choose whether  D200 to D511 are latched or not, the 'fixed latched' are just as stated fixed.  
  14. Download the manual no. JY997D16601 and look at the 'devices in detail' it explains how to configure 'D' registers and which ones are battery backed etc. Steve
  15. Mitsubishi FX2N PLC to GOT 1000 HMI

    I believe that the GOT1000 serial port you refer to may actually be a rs422 to rs232 converter plugged into the HMI, if you look carefully I think you'll find it's removable (well it is on my GOT1504).
  16. Set Status bit S:1/8 to '1' this clears the major/minor fault bits on power up, unfortunately this needs to be set offline in the program then downloaded to the processor, I would be more concerned as to what is causing the faulting of the processor and solve that issue.
  17. Lacthed Memory Turned Off?

    Check for something like K2M100, where the M100 in this example represents your latched bits, the example shown actions M100 through to M115, the K2 represents 2 nybbles (2 x 4bits) also check the used devices list. are the addresses being written to by a HMI or external equipment?
  18. FX2N program

    You don't need to type in |STL|, just the S20, So F5 to get | | then enter S20   Steve
  19. How to make a recipe?

    If your post is correct you are using the GOT Special Internal device (GS) these only have a range of 0 -2047 (depending on the display type), You should be using GD (range of 65535) Steve
  20. Try %MW100:X0 to %MW100:X15 Steve  
  21. I've not used the latest software or HMI's, but with the GOT1000 & GOT2000 with RS232 you have to set enable the 5Volt power supply in the HMI utility setup for the comm port. Steve Sorry should have read the post carefully didn't see it was a proface. On the same note - try selecting it to VCC, I think this is similar to the GOT's.    
  22. For One shotting a p/button take a look here :-10 ways to toggle a relay using one p/button Steve
  23. FX3U (le3u) countdown timer?

    For a simple countdown display for a HMI or anything else for that matter, just subtract the timer (counter, whatever) accumulated time (value) from the preset. Steve  
  24. SER Intsruction Help

    SER instrustion is a search function, in your example D2504 is the start of the search array, D2601 is the value it is searching for, D2501 is the position within the array it found the match, D2600 is the number of elements in the searched array. The values in D2504 and D2601 are changing because somewhere in your program they are being indexed either directly or indirectly, you would need to find these to understand what is being achieved with this coding.   Steve
  25. The .ACH extension was used for the Allen Bradley 6200 software, if this is the case RSlogix500 should still be able to open it.   Steve
