  1. I see no picture attached. However, I think what VisiLogic does is omit zeroes in the OS version number so that what you actually have on the PLC is 4.004. If VisiLogic is asking you to upgrade the OS, then you must in order to download a new project. Be prepared for it to take several minutes. Also, I have had it fail on occasion, but just repeat the procedure and it will be fine the second time.
  2. What do you mean by "reset"? If you mean erase the program that's in there, then downloading a new program will do that automatically.
  3. Think about what ladder logic is all about. It's a high level language where each ladder rung is intended to encompass a single line of code. It's not just a blank slate with some random lines drawn. Separate lines of code belong in separate ladder rungs. You tried to put 4 lines of code in a single ladder rung. Sometimes you can get away with it, but it's fraught with risk and is very poor form.
  4. If it's just a toggle button to turn a pump on or off, you don't need ANY ladder logic at all. Simply assign the output to a binary text switch and check the Toggle box.
  5. See above on where to find the info in the Help file. While you could certainly map the I/O directly to MBs in the program, it is not automatic. The Help file provides the addressing for the MODBUS Master to find the I/O coils. They would be addressed just like any other coils, just higher up in the address table. Being a MODBUS Slave is not sufficient to be able to read data from the PLC. You must have a SCAN_EX function block running in the program to scan for incoming MODBUS requests.
  6. The digital I/O on the expansion modules is numbered sequentially starting at I-32 for inputs and O-32 for Outputs. All the information you need to know is in the help file. Search on MODBUS Slave Addresses. Click on MODBUS,IP, then Slave Addressing. There you'll find the addresses for the different operands in the PLC, including the addresses for the I/O. You'll need access to the PLC program unless the program is already set up to be a MODBUS Slave.
  7. @Cara Bereck Levy, best as I can tell, this has not been done.
  8. It's a short comedy skit with IT folks repeating "Have you tried turning it off and back on again" over and over again to all of their support requests.
  9. Then you should be able to adjust the settings to allow you to connect over Ethernet. And yes, I have had that procedure solve the problem in the past.
  10. Try downloading a BLANK program, Initialize & Reset, check for touchscreen functionality, then download your program again.
  11. Moved to a more appropriate forum.
  12. @viscoelastic and @Joe Tauser - Thank you! All is good now. I was able to find the "InstallShield Installation Information" folder and deleting it solved my problem.
  13. Thanks, @viscoelastic. That folder does not appear to exist on my computer. I poked around a bit and did find an InstallShield folder elsewhere (under Common Files), but nothing seemed relevant to VisiLogic.
  14. I have a brand new Windows 10 desktop computer and cannot get VisiLogic to install. Here is the error message: Any idea what might be the problem? FYI, I have turned off UAC and attempted the install using "Run as Administrator".
  15. Apparently someone on this forum has good reading comprehension. It certainly isn't me!
  16. I'm sure my quick action is what saved me. The power supply I normally use in my office is 4.2 A (100W). Sometimes when setting things up for a quick test I get in a hurry and don't triple check the connections, but I've modified my bench with a bunch of pre-wired 5.5mm barrel connectors so that reverse polarity is no longer possible.
  17. I have reversed the 24V power supply leads on my test bench Vision PLCs (including V1210s) many times. Each time was for only a few seconds, as it was immediately obvious, but that has never caused damage to any of my PLCs.
  18. The V700 has equivalents to all the Ethernet System Bits. In this case Socket Status Request #22 would return the value of 23. Go to the help file and read the topic "Vision700 - Using Ethernet".
  19. I am programming a V130 PLC using VisiLogic 9.8.80. I have placed a Password variable on the screen for the user to enter a numeric password. However, when the screen appears, the user must press “Enter” before entering the password in order to make the variable “Active”. It’s the only variable on the screen. According to the Help file (see below) the display should load with the variable “Active”, but it does not. What do I need to do to make the variable default to “Active” when the screen is first loaded?
