9.4 Changing data
The user must enter the correct password before he can change the machine data
for SI functions to the system. After data for SI functions has been altered, a new
acceptance test must be carried-out on the SI function(s) involved and then re-
corded and confirmed in the acceptance report.
Change report
Changes made to NCK machine data important for Safety Integrated are recorded
in a display data. The times that these changes were made are displayed in axial
MD 36996: $MA_SAFE_CONFIG_CHANGE_DATE[0...4].
This MD can neither be overwritten by manual entry nor by loading an MD archive.
It can only be deleted by booting the control from the general reset mode (switch
position 1).
This data is updated when the following changes are made to the NCK machine
data:
S When a modified safety MD configuration is activated
(NCK safety MD have been changed and acknowledged by correction of
$MA_SAFE_DES_CHECKSUM).
S When MD $MA_SAFE_FUNCTION_ENABLE is changed from values not equal
to zero to zero, or from zero to values not equal to zero. These changes mean
that the safety functionality of an axis is completely enabled/disabled. Other
changes to MD $MA_SAFE_FUNCTION_ENABLE always change MD
$MA_SAFE_ACT_CHECKSUM, which themselves have to be acknowledged
by changes to MD $MA_SAFE_DES_CHECKSUM.
S When MD $MA_SAFE_FUNCTION_ENABLE is changed by reducing the sa-
fety option. If the scope of axial safety functions is enabled for more axes than
are set in the safety option data, the function enable for the excess number of
axes is automatically cancelled again when the control boots.
S Loading an MD archive that is different to the currently active NCK-MD set.
S When upgrading (corresponds to downloading an MD archive)
S Series commissioning (corresponds to downloading an MD archive)
Limitations and constraints
Changes to the MD configuration are only noted when the change becomes active,
i.e. after altering MD $MA_SAFE_DES_CHECKSUM and a subsequent power on.
This MD is calculated - also for axes that were not released for Safety Integrated.
