uploaded, indicating that "the program does not exist".

need to input the correct password when uploading the PLC program; if you check "download
program needs to be decrypted first", you also need to input the correct password when
downloading the new program to the PLC. Under this mode, you can not modify the clock
information of the PLC, and the confidentiality is stronger.
