Harry Posted March 16, 2020 Report Share Posted March 16, 2020 I am working with a unitronics vision 570 PLC. I am doing a burn upload project and then when I try to verify , there are two cross marks in verification. These crosses are against PLC DLU memory backup. Sp any suggestions on how to fix that?

MVP 2023 Flex727 Posted March 16, 2020 MVP 2023 Report Share Posted March 16, 2020 I haven't run across this before, but as a general rule when I have issues with downloading I do the following: - Confirm the version of VisiLogic that you are using matches what version was originally used to download the project. - After making sure you have a saved version of the project, download a BLANK project to the PLC. - Download your original project again. - Now try Burn Upload Project again.
