  1. Glad to report that problem here has been solved!! As it turns out, the problem is VMWare and U90s inability to communicate properly in that environment. Installed U90 in the non-VM Win 10, and once we were able to run it with admin privileges (grrr, corporate computing systems...) it communicates like it should with any of the 4 USB to serial adaptors we'd amassed. I have not seen any reference by Unitronics to U90's compatibility with VMs.
  2. Thanks for the response Ausman. I too most certainly miss the dedicated serial port in a laptop. We don't have any such beast left here, so adaptors are our only way. I have connected to a myriad of brands and types of devices with this particular MOXA adaptor and laptop, and this is the first potential problem device. I didn't know there was a battery inside this PLC, no mention of it in documentation I've seen. I will look for another USB-serial adaptor with Prolific chip and have another go. Edit - looking at Shentek adaptors, they all say FTDI chip. No good?!
  3. Thanks for response kratmel. Checked project - password not set.
  4. A fair few years ago we installed U90 on a laptop running XP to support a M91-2-R1 we have installed in a small filling machine. Used software and DL and UL on and off for years with no issue. Laptop had dedicated serial port. Life was good. Then filling machine sat dormant for a few years. Now filling machine is being re-commissioned and our new laptop is running VMWare, where we can still use our old XP environment. For the life of me, I am unable to establish an RS232 connection to UL or DL to PLC. Yesterday - running U90 version 6.01 in WIn XP 0n VMWare, Moxa UPort USB to serial converter, checked device mgr, Moxa is COM2. In M90 OPLC settings, tried every possible setting and unable to establish a connection, However using Controller>Operating System>Check Current OS, set to COM2 communications is established and reports PLC OS is up to date. Using Tools>UniDownloader Designer>Get OPLC Information, Get Com Parameters and Get PLC status all establish comms and reports PLC info as it should. What is it about M90 OPLC settings>PC Communication Port Settings that just refuses to connect even though other comms dialogs clearly work fine. I'd think this rules out a hardware problem?! Today I DL the latest revision of U90 and installed in a Win 7 environment in VMWare. In this Win 7 OS, the Moxa port adaptor is COM3, and I have exactly the same issue. PLC OS check and UniDownloader Designer can both establish comms with PLC, but M90 OPLC is just unable to establish a connection. In both instances, I'm running U90.exe as admin. I'm at my wits end. Can anybody help?
