I was working with a UniLogic project when the computer shut down. Reopening the project with VisiLogic gives me the following error: "This project was created with an later version of UniLogic, and cannot be downgraded. Please open this project with a newer version of UniLogic" Now I'm not able to open the project and I use the latest version available: 1.18 rev 60
Hi, I have purchased two Jazz R16 PLCs, and trying to reprogramm them to my needs, the only problem I have got is that after I switch power off, all the data saved in the PLC is gone or restored to defaults. Also while I am recompiling the programm and trying to download the program to PLC, I see the power up values - retain values grayed out. What should I do to enable it? I have opened the Jazz, and have seen the Letium battery on board, so I beleave it is good battery, also SB8 return a 0 value. How can it be that the values does not been saved?
