IDEC SmartRelay memory cartridge (card)
243
IDEC SmartRelay Manual
6.1 Security function (CopyProtect)
We principally distinguish between memory cartridges (card)
with and without circuit program/copy protection.
Unprotected memory cartridge (card)
You can edit circuit programs without restrictions, and ex-
change data between the memory cartridge (card) and the
IDEC SmartRelay.
Protected memory cartridge (card)
A circuit program is protected when it is transferred from a
protected memory cartridge (card) to the IDEC SmartRelay.
To execute this circuit program in IDEC SmartRelay, the pro-
tected memory cartridge (card) must remain inserted during
RUN, i.e. the circuit program stored on the memory cartridge
(card) can not be copied to other IDEC SmartRelay devices.
Over and above that, a protected circuit program is write-
protected.
A circuit program with password protection is no longer pro-
tected after the correct password has been entered, i.e. you
can then edit the program and remove the module.
Note
You need to assign a password when you create the circuit pro-
gram for a protected module (card) to be able to edit it at a later time
(see Chapter 3.6.5).
