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)
