6.1 Security function (CopyProtect)
The secuirty function provides copy protection for circuit
programs on memory cartridges or combined memory/
battery cartridges.
Unprotected memory cartridges
You can edit circuit programs without restrictions and
exch
ange data between the memory cartridge or combined
memory/battery cartridge and the device.
Protected memory cartridges
A circuit program is protected
when it is transferred from a
protected program memory cartridge or combined memory/
battery cartridge to IDEC SmartRelay.
To execute this circuit program in IDEC SmartRelay, the
protec
ted cartridge must remain inserted during RUN; that
is, the circuit program stored on the cartridge cannot be
copied to other IDEC SmartRelay devices.
Over and above that, a protected circuit program is write-
pr
otec
ted.
A circuit program with passwo
rd protection is no longer
protected after the correct password has been entered; that
is, you can then edit the program and remove the memory
cartridge or combined memory/battery cartridge.
Note
When you create the circuit program for a memory cartridge or
combined memory/battery cartridge, you need to assign a
password to be able to edit it at a later time (see Chapter 3.6.5).
