  1. Floating license

    Just to follow up... "Borrow" seemed more trouble than it's worth, for a single user (mostly as my vendor has no idea what the "borrow" license is).  In the end, I just put the license on the laptop and just have to keep it turned on while I work on the desktop.
  2. interger as a coil in codesys

    You should get a type mismatch error doing that. You can address a bit in an int and use it for coils: (int).00 = first bit, (int).01 = second bit.
  3. Floating license

    Hi Bob!  Thanks!
  4. Floating license

    Hi, I got the floating license so I could have copies on my desktop computer (for development) and the laptop (for installations). Is this possible?  The laptop won't have access to the office network when on sites. Thanks, Larry
  5. Portable VPN

    I've found some devices that connect via Amazon AWS.  A few can connect to the 'net via RJ45, Wifi, cell, or USB (for phone tethering).  I'll buy a couple of those and see how they work out...
  6. Portable VPN

    I've considered going the TeamViewer route as a last resort, and for this upcoming service it seems I'll have to go that way.  I'm not a big fan of TeamViewer, though, do you have an alternate favorite? Thanks!
  7. Portable VPN

    Hi All, I'm looking for a vpn device that I can mail to a client, have them pop their sim card in it or connect it to wifi, and it'll allow me to connect via ethernet to their plc, etc... I'm thinking something like the Phoenix mGuard, but I have no experience with that and don't know if it's any good. Anyone done this? Thanks, Larry
  8. Old Medoc and a F1/F2 plc

    Use Medoc 2.40, it's a win32 text mode app.  Works fine with usb serial ports.
  9. Wago 750-881

    Set the dip switches back to the default.  If they are set to an address, the 881 will use it. Also, download the "Wago ethernet settings" utility.  It's a better way to set up the PLC.
  10. F940GOT firmware

    Well, since no one else answered this... As I recall (and this has been a while), I was using the SW2D5C software, and that included the OS, which may or may not be newer than the OS that shipped on the screen. When you download, there is an option to install the OS.
  11. Unbricking an FX3G

    Revisiting this, while these plcs look really clean inside, looking at them again under a powerful magnifier, I found corrosion everywhere. I suspect they got exposed to concentrated ammonia or chlorine gas. Thanks for your suggestions!

  13. Unbricking an FX3G

    That's another problem, my long-time local MEAU distributor is no longer an MEAU dist, and the new guys know nothing (and stock nothing). The MEAU tech support guy wanted me to send it to them, but I suspect that'd be a waste of the shipping fee.
  14. Unbricking an FX3G

    Yes, I tried switching to stop. Bear in mind that the code worked fine for a year and then it bricked. It's the same code I have running on a couple hundred installations, all with no problem. On site, it's connected to two FX2N-4DA modules, but those seem to be working. There's a third, new plc in place now that's working fine, no changed to code, config, nor wiring.
  15. Play Music with PLC? or what else?

    You could just use one of these with a PLC, cheap and easy to connect: https://www.gilderfluke.com/index.php?main_page=product_info&cPath=1_3&products_id=33&zenid=2i4daoque795uddppgbff8k8j187imo7
