Program Execution; Application Program Licensing And Protection - ABB ACSM1 Firmware Manual

32

Program execution

The application program is loaded to the permanent (non-volatile) memory of the
memory unit (JMU). When the loading finishes, the drive control board is
automatically reset, and the downloaded program started. The program is executed
in real time on the same Central Processing Unit (CPU of the drive control board) as
the drive firmware. The program can be executed at the two dedicated time levels of
1 and 10 milliseconds, as well as other time levels between certain firmware tasks.
Note: Because the firmware and application programs use the same CPU, the
programmer must ensure that the drive CPU is not overloaded. See parameter
CPU

Application program licensing and protection

Note: This functionality is only available with DriveSPC version 1.5 and later.
The drive can be assigned an application licence consisting of an ID and password
using the DriveSPC tool. Likewise, the application program created in DriveSPC can
be protected by an ID and password. For instructions, refer to the DriveSPC user
manual.
If a protected application program is downloaded to a licensed drive, the IDs and
passwords of the application and drive must match. A protected application cannot
be downloaded to an unlicensed drive. On the other hand, an unprotected
application can be downloaded to a licensed drive.
The ID of the application licence is displayed by DriveStudio in the drive software
properties as APPL LICENCE. If the value is 0, no licence has been assigned to the
drive.
The parameters that are created using the DriveSPC parameter manager with hide
flags can be viewed or hidden by parameter
must be the same as the drive APPL LICENCE. A wrong password code will hide the
visible application parameters again.
Notes:
• The application licence can only be assigned to a complete drive, not a stand-
alone control unit.
• A protected application can only be downloaded to a complete drive, not a stand-
alone control unit.
