Security enhancement

Programs are copy-protected by the upload restriction setting and an eight-character password.

The setting to inhibit the uploading of PLC programs to PCs protects your programs from unauthorized copying. (If this setting is released, programs in the PLC are forcibly cleared.)

An eight-character password has been adopted. (The conventional four-character password is also available.) Approx. 218 trillion passwords can be set by combining eight alphanumeric characters, making it nearly impossible to crack the password set.

Debugging performance enhancement

Up to 512 steps can be rewritten simultaneously in RUN mode.

This improvement allows efficient program debugging without stopping the operation.
