Operation When Security Functions Are Enabled

This section describes the operation when security functions are enabled.

When a security key is set

When a security key is set to the boot target program file and the security key of the program file does not match with that of
the CPU module, a boot error occurs. Also, when no security key is written to the CPU module, a boot error occurs as well.
