Special Message #15: Enable HE Stack
Special message #15 enables the Historical Event Recording Stack. After
special message #15 is triggered, messages designated as stackable messages
are stored in the Historical Event Stack as they are triggered.
When the DL20 enters run mode, this is the default condition. It is not
necessary to trigger special message #15 to enable the Historical Event
Stack. It is usually used to turn on the Historical Event Stack after it has
been turned off by special message #16.
Special Message #16: Disable HE Stack
Special message #16 disables the Historical Event Stack. After special
message #16 is triggered, messages designated as stackable are not stored as
they are triggered. The Historical Event Stack remains disabled until power
is cycled or until special message #15 is triggered.
Special message #16 is useful when your application has a set-up or test
mode and messages are being stored in the Historical Event Stack having to
do with production counts. You may not want to stack messages with
production counts in them while in the set-up mode or when manufacturing a
few test parts. To do this, trigger special message #16 when the machine is
in the test mode. Now as the operator goes through a few practice sequences,
triggering messages such as part dimension xx inches, or batch temperature
was xx for xx minutes, these messages are not recorded in the HE Stack.
When the operator is ready to make an actual production run, he switches the
machine over into the production mode. At this time, special message #15 is
triggered so messages are stacked again.
