Hello, This is probably not the place to look for parts but I thought I would try. I am coming up short on (12) expansion modules ( IO-DI8-R08) or (IO-DI8-T08) and I am having a hard time locating some within my needed time frame. My dealer is saying 4-6 weeks from Unitronics. Anyone know of a stocking supplier to check out within the US? Thanks.

Sorry, I meant multiple downloads per site but not simultaneously. I often have multiple PLC's per site that all run the exact same program, so if I update one PLC, I also need to update all the other PLC's that run the same program.

I was sure it seemed to help right after you advised me to try it...but then the next day I wasn't sure anymore. Obviously I never know how strong the internet connection is on the other end so that might make all the difference. P.S. Thanks for the advice, I'm still learning things every day about Unitronics so every tidbit of info is valuable to me! This forum has been a huge help for me over the past several years.

Just to clarify, I was referring to downloading over WAN. It seems maybe in your application you are downloading within the same network. I have no issues either downloading within LAN. I have many PLC's online and I do updates remotely without being at the jobsite. This is a great selling feature and it works great most times. However with doing multiple downloads per site, the connection usually is not stable enough to do more than one at a time without doing a computer reboot. Doing a computer reboot almost always works, but I don't know why it does...? Even with putting SI 101 at a 10 power up value, I still have issues with getting the (210) error message.

Hello, Has anyone had difficulty downloading a program remotely using TCP/IP (Call)? Usually the first attempt may or may not work, 50/50 chance it seems. ( Communication Driver Error 210 Message Appears) I learned that if the first attempt does work, the 2nd download will not. The only way I have gotten around this issue is to shut down Visilogic and do a restart on the computer. After restart, the program will usually let you do another download but rarely a 2nd one without another restart. Also, I always need to be lightning fast on the prompts that appear (around 1 second max) or the 210 error message will come on again. I tried to lengthen all the timeouts to maximum values but it makes no difference. Any suggestions? Thanks!

Thanks Guys! That worked and saved me many hours of HMI construction! For some reason if I opened the 91 version in 65 and saved it; it still refused to open in 65. So I tried to export the HMI displays while having it open in 65 but when I tried to import the displays to my new 65 version, they still refused to import. But, if I copied the display, opened my new 65 version I was making, then add new display and pasted the display, it worked fine. I just had to do that many times but it was well worth the bother. Thanks again! I agree Flex, that the optimum would be to get to the bottom of the 91 version issue(s). Unitronics Support was totally awesome on working with us on it. I felt bad calling again and again with all of our complications we were having with it but they patiently worked with us through it all! Seems the flashing screen problem could mostly be resolved by going into the registry editor and deleting all the (vlp_auto_file) but we never could quite get to the bottom of the file explorer crashing problem. File explorer would crash consistently after attaching a program file to an email, or, saving a program to a cloud based file storage application like Google Drive. Sometimes it would crash without us knowing why. We now have one laptop specifically for 91 version so if it crashes beyond our expertise to repair it, we have nothing of much value on the laptop. I understand there are other folks using 91 version without the issues we were experiencing so maybe the biggest problem is our own unique way of running the system...

Hello, I had to update my trusty 9.8.65 Version to the new 9.8.91 Version to accommodate a Servo + VFD application. This 9.8.91 version gave us many challenges with our windows laptops, (i.e. File Explorer Crashes and Flashing Screens.). We have since gone back to 9.8.65 but not before I had finished several other projects in the 9.8.91 Version. My question now is if I can transfer my HMI screens back to 9.8.65 from 9.8.91? I was able to transfer all the ladder code back but the HMI refuses to be transferred because of the version differences. Any suggestions? Thanks.
