  1. Glad your problem is solved. Thanks for reporting back.
  2. Also remember that any operand in the middle of a vector will not be found using the search function.
  3. Yes, the V700 supports MODBUS protocol over either serial or Ethernet. There are example projects that came with your VisiLogic installation that will show you how to set up MODBUS communications.
  4. What does? The V700 most assuredly does NOT communicate with Ethernet/IP. Perhaps you're connecting with MODBUS?
  5. It doesn't really delete anything. Just click OK and continue on. Since they're both TA24 models, all the digital I/O will be exactly as it was. You will have to re-assign the analog I/O, but that just takes a few seconds. Make sure you know the assignment in advance. What do you mean by this?
  6. There is an Upload program function in VisiLogic to allow you to upload the program from the PLC to VisiLogic, but unless the original programmer downloaded the program with the Upload project function enabled, it cannot be done. Just go to Connection / Upload while connected to the PLC and see if it lets you.
  7. The RJ11 port on the PLC is a standard serial port. Converting from USB to serial is fairly straightforward (I think), but I'm not a wiring guy. I have seen USB-to-RJ11 cables on the market. Yes, the RJ45 port is for connecting external I/O modules. Unitronics has a lot of documentation available online. I recommend reviewing it. Here is the User Guide for the V350-JT38: https://unitronicsplc.com/Documents/Vision/PLC/UG_V130_350_430-T38.pdf
  8. When I had this requirement, I purchased a UniStream USC-B5-B1 and used it as a gateway between the Vision PLC and the OPC client. The Unistream talked MODBUS TCP to the Vision PLC, collected all the data, then made it available to the OPC client. It was inexpensive and worked perfectly.
  9. Typically you can get the V700 for nearly the same price as the V570 + Ethernet card, as the V700 already has Ethernet built in. Yes, actually the keyboard and other items under control of firmware (as opposed to the application) are the same number of pixels, but the V700 screen is higher resolution. The higher resolution allows for more detail and sharper images, but there is that (IMO minor) tradeoff that Fernando mentions.
  10. Based on this, my first recommendation would be the V700. It has a 7" color touchscreen with a widescreen format. If you should decide you need a larger screen, then the V1040 (10" screen) or V1210 (12" screen) are available. With all the Vision PLCs you can access the PLC through Ethernet from a PC or your phone. The V700 can be in constant communication with 8 other devices simultaneously over Ethernet and also has serial comms, if needed.
  11. Yes, the Vision PLCs should be able to do what you want. Additional questions: - What is your budget? - What size HMI were you thinking? - Do you want touchscreen? - Do you want a color HMI? - Do have any communications requirements (e.g. Ethernet)?
  12. Digital inputs (and outputs) do not need to be "linked". You use them in ladder or HMI exactly like MBs. Regarding linking analog I/O, that is part of the firmware that performs the analog-to-digital or digital-to-analog conversion required to interact with the external world (the external world is all analog and the PLC is all digital).
  13. I'm having trouble making sense of your question. Digital Inputs are hardware. They correspond to specific terminals on the I/O module (in your case the I/O module is part of the PLC). How could they not be "fixed"?
  14. Of course. I password protect buttons and screens all the time. There are various ways to do it, but VisiLogic has a password HMI element built right in.
  15. I think I may start including this with all my code:
  16. I've never seen that option in any version of VisiLogic (since 7.0.1 when I started).
  17. Is your V1040 new, or does it already have a program in it? If there's already a program, it may have initialized COM1 as something incompatible with VisiLogic. Go into INFO Mode and check it. Also, screenshot your Connection window so we can see if that is set up properly.
  18. You can't take the requirement for an SD card out of the program?
  19. Didn't Unitronics get their start by developing automated parking garages? They had an elevator, of sorts, to move the cars around. I can't find that information on their website anymore, so perhaps I'm misremembering.
  20. That's certainly interesting - and something to note, but why would you want that window closed??? It's very important and constantly needed when writing your program.
  21. Seems like this is easily within the range of a 32-bit signed integer. It may be "easier" to work with floating point, but if they don't work then the harder path is necessary.
  22. It's still right there in the original post - hasn't moved.
