Emi Posted March 10, 2020 Report Share Posted March 10, 2020 Hi there , can anyone give me some tips , hints or examples about this topic. I am sure anything will be a great help. I made a program with a few displays where are one or two keypad entry variable . I just want to scroll between the displays to see the values of variables ( this I all ready made with keypad force entry) and when I want to modify the values of variables a password entry will appear. In this case the variables will be protect against changes made by unauthorized persons . Best regards. Quote Link to comment Share on other sites More sharing options...
AlexUT Posted March 10, 2020 Report Share Posted March 10, 2020 You published your question in "Jazz, M91 PLCs and U90Ladder" branch. What PLC model do you use? B.R. Quote Link to comment Share on other sites More sharing options...

Emi Posted March 10, 2020 Author Report Share Posted March 10, 2020 Actually I work on that to implement on my project, but until now I didn't manage to do it . I'm stuck at validation password and enter the new variable parameter. My condition is when the display is not equal whit the main display and" Enter "key is press (SB 53) it jumps at password display . At this point I'm stuck because I can't enter any password and I think there is a condition in my program to influence that . Thanks anyway for your support and the fast reaction on my topic.

Did you find a password to unlock the JZ 20 ? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted April 15, 2020 MVP 2023 Report Share Posted April 15, 2020 Define "unlock". EMI was working on trying to enter a user-defined password. What problem are you having? Joe T. Quote Link to comment Share on other sites More sharing options...
Emi Posted April 21, 2020 Author Report Share Posted April 21, 2020 Hi there ESK and sorry for so much delay. but I think you don't have the same problem. I actually put a password for enter the variable set by me. I didn't discover some password to unlock the plc , that because was new and i did the programming . If your Jazz is not new and have already a program installed which is protected by a password you need to contact the supplier who make the program or the equipment. good luck.
