ProgContrSys Posted July 21, 2018 Report Share Posted July 21, 2018 Hi all, I have start to use the V700 with VisiLogic 9.8.65. During my programming I had problems with downloading. See the attached picture. Somebody has a solution for this issue? Thank a lot to all. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted July 21, 2018 MVP 2021 Report Share Posted July 21, 2018 Try downloading a blank project first, then try your project again. If you still get a failure, make sure the V700 has the latest firmware. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted July 21, 2018 MVP 2021 Report Share Posted July 21, 2018 I've had this happen - it seems to be caused by a communications / order of operation timeout. Are you downloading over the serial port or the Ethernet port? Joe T. Quote Link to comment Share on other sites More sharing options...
ProgContrSys Posted July 22, 2018 Author Report Share Posted July 22, 2018 Hi. I use unitroncs cable - USB to Serial communication. Time out for communication 1.5 Bit Rate has been set to 115200, 38400. During downloading a new empty project I have same issue. My program has not include any errors or warning. Same program has been downloaded to this PLC last week, and has been checked real time. But this problem come back time to time. Quote Link to comment Share on other sites More sharing options...

MVP 2021 kratmel Posted July 22, 2018 MVP 2021 Report Share Posted July 22, 2018 Try to use older version visilogic to download blank project. Try to use external usb to com converter for connection. Try to load the same project without any images (displays). Check all V700 power supply connection. As i see flash memory maybe corrupt :( Quote Link to comment Share on other sites More sharing options...
viscoelastic Posted August 1, 2018 Report Share Posted August 1, 2018 I have ran into this problem. It was the USB to Serial converter. Have you tried plugging the USB directly into the mini-b on the v700? also try knocking down your baud rate down and see if that works.
