  1. I don't think the FX3s Supports bit level actions on Data files, ie D1.0 is not allowed, you could convert the D file to M bits by (MOV)ing D file to K4M0 using the M bit then convert back to D file (MOV k4M0 D0) or conversely use the GOT display to do the donkey work utilising scripting.   Steve
  2. Got Simple vs Siemens S7-300

    The example from the help file appears to be incorrect, The data blocks in s7-300 are natively byte wide (8 bits), the GOT registers on the other hand are 16 bit wide, so it requires 2 bytes of the Siemens DB to make up a 16 bit integer in the GOT. DB1.DBX0.0 - > DB1.DBW0.b0 DB1.DBX0.7 - > DB1.DBW0.b7 DB1.DBX1.0 - > DB1.DBW0.b8 DB1.DBX1.7 - > DB1.DBW0.b15 etc., etc.
  3. FX2N-16EYR Error Output

    Or if you are using 16 bit devices you can use [= d200 d300 m200], [> d200 d300 m200],[< d200 d300 m200] etc. which will only use the one result bit (eg M200), the compare function CMP would be required for 32 bit compare. The manual is quite intuitive,  
  4. VFD Analog output to LOGO!

    Extract from the manual,   abb VFD.pdf
  5. VFD Analog output to LOGO!

    It would appear that the VFD does not have an analogue voltage output , only a 0 to 20mA current output. You can modify the Logo input to read current, or you could use a 500 ohm resistor to convert to 0 -10V.   Steve
  6. GX works 3 - new version change log

    If you generate an account with Mitsubishi Automation and register your software, it will verify your version and it will notify you by email whenever there is an update, it does this with software and documentation with links to download (free of charge).   Steve
  7. if you generate a virtual machine, you can reinstall it on there for another 21 days Note! you can only upload the screens and data from the HMI if the project source code was downloaded with the runtime files. The runtime files are compiled and not editable. Steve
  8. panel meter

    I think you are getting confused with the preview function, this is not a simulation only a graphical overview of your screen. That said, you can click on the panel meter graphic and modify the displayed value, but it will not dynamically follow your numeric input. To have it dynamically change the panel meter graphic in line with your numeric input you need to simulate it, which if installed will be accessable under the 'tools' dropdown. Steve  
  9. Overlap Window Title

    You need to right click on the 'Windows Screen' not the 'New' and use the 'Window Dialog Wizard' to generate a new window.   Steve
  10. GX Developer

    I believe GxDeveloper is an outdated software for Mitsubishi PLC's, though it will run a large majority of the older processors, the current software would be GXWorks, this is what is required for your processor.   Steve
  11. you can generate your own oneshots, something like these,     Steve  
  12. Problems opening a file in studio5000

    RSlogix5000 and studio5000 are revision specific, it depends on what the program revision is as to what revision of studio5000 you need installed on your PC For example if the program is written in version 20 then you need version 20 installed on your PC to open it, even if you have a later version installed, say version30 it still won't open it, it has to be version 20 Steve
  13. 1747-SN relates programming question

    You could try posting in PLCtalk.net, http://www.plctalk.net/qanda/forumdisplay.php?f=2 The guy's on there are far more AB Savvy, there are ex (or current) AB employees amongst the moderators. Steve
  14. Not able to select parameter

    Welcome, To save us trying to second guess your problem, could you give more info ie what piece of equipment are these parameters relating to? Steve
  15. 1747-SN relates programming question

    I'm not sure about the *QMS part but the S:15 is split into low byte and high byte where the low byte contains the NODE number of the Processor and the high byte contains the baud rate of the com port, is the QMS a symbol for a memory store? Steve
