DanT Posted September 3, 2020 Report Share Posted September 3, 2020 Hi; If program Upload is password protected, you cannot upload it without the password. If they set the Properties to Block PC Access, then you are out of luck -- all communications is blocked -- You will have to get a new JAZZ PLC and program it with a new program - Your Way. BUT If the Block PC Access, has NOT been Set, then You can download your new program overtop and replace the previous program. ( The password required for the old program will also be gone with the old program) DanT Quote Link to comment Share on other sites More sharing options...
