Fig. 12. Change configuration parameter page.
For safety configuration parameters an additional verification
step is required to commit the changes.
Safety parameters are grouped into blocks that include only
safety parameters, not a mixture of safety data and non-safety
data. All parameters within the safety group undergo a
verification process. A safety parameter group is identified on
the 833-3577 to indicate when the configuration parameters
are safety-related. Each safety parameter group is verified
one at a time until all have been verified. See Fig. 13.
Fig. 13. Safety verification.
Safety parameters can be viewed the same way non-safety
parameters can be viewed. If the user makes no attempt to
change a safety parameter, the user isn’t required to enter
safety verification mode.
A verification step is required for each safety parameter block
that is changed. The verification steps do not have to be
completed immediately; the user can traverse between
parameter groups before the verifications are done. A Verify
button is enabled that allows the user to conduct verification
sessions (the Verify button in Fig. 8 is not yet enabled
because the user hasn’t logged in).
NOTE: When the user proceeds with the safety parameter
configuration the 833-3577 requests that the 833-
3639 enter this mode. In this mode the 833-3639
unlocks the safety parameters in this group and
marks them unusable. Failure to complete the entire
safety configuration procedure leaves the 833-3639
in an un-runnable state.
All safety configuration parameters in the group should have
the same access level. If this condition isn’t so, the user is
asked to enter another password when a higher access level
is needed.
Successful entry of the 833-3639 into safety verification mode
is displayed and the lock icon will appear "unlocked" on the
page with the first safety block displayed. The user may begin
to change safety parameters (or any other parameters) at that
time. See Fig. 14. If the 833-3639 is already in an un-
configured state, then this warning doesn’t appear. All
parameters that need it should be changed during the edit
stage.
Fig. 14. Edit safety data.
If the user terminates the safety configuration session after it
has started (in the Edit or Confirm stages), the 833-3639 is left
in an unconfigured (unrunnable) state.
The user can terminate the session by pressing the Menu
button or by attempting to leave the Verification page with the
Home or Back buttons (top-left and -right screen corners,
respectively). The user is warned that leaving the session at
this point leaves the 833-3639 in an unrunnable state and
confirms whether the user still wants to do so.
The settings of all parameters in each safety block must be
confirmed to commit them in the 833-3639.
When the user is done changing safety parameters, pressing
the Confirm button begins the confirmation stage. The settings
for all safety parameters in each changed block are presented
and confirmed by the user (see Fig. 15).
