10.2.1 Program password protection
ou can protect your circuit program from unauthorized access with a password. IDEC
strongly recommends you use the password-protection to prevent unauthorized reading or
editing of your circuit programs.
For more information about assigning and changing a program password, refer to Section
Password for circuit program protection (Page 70).
10.2.2 Program copy protection
The Copy Protect function provides protection for the circuit programs on micro SD cards. A
circuit program is protected when you transfer it to a protected memory card.
This additional security feature allows you to bind the circuit program with a specific memory
card.If you copy a protected circuit program to another memory card, IDEC SmartRelay
cannot recognize the program and reect loading it after you insert the card.
To execute this circuit program in IDEC SmartRelay, you must leave the card in the IDEC
SmartRelay Base Module during RUN mode that is, you cannot remove the card to copy the
program to other IDEC SmartRelay devices.
A circuit program with password protection is no longer protected after the correct password
has been entered that is, you can then edit or copy the program and remove the card.
