e. Update Acknowledgement: This sets the acknowledge that the group has
triggered and can be reset to rearm the triggered group for the next
triggered event.
f. Send on Connect: This setting controls whether to send data immediately
upon connection. Enable or Disable.
g. Update Policy: This sets the policy determining what values in a group are
sent when an exception is met:
i. Send Only Changes: This policy is most common and means that
upon each evaluation of the group, only parameters that have net
the exception will be time stamped and sent.
ii. Send All On Any Change: This policy that if any parameter meets
exception values, it will send all parameters in the group.
iii. Send All Each Time: This policy will cause all parameters to be sent at
each time period whether any exception is met or not. To be clear, all
parameters will be sent every time period.
h. Maximum Interval: This setting will cause the group to send each
parameter in a group at least this often. Note that this feature is
implemented on a per-parameter basis, such that it does not force the
entire group to be sent every so-many seconds, but rather forces additional
transmissions so that each parameter is sent at least that often. The timing
and contents of this transmissions will depend on whether each parameter
has already changed within the specified period.
i. Send Anchors: This feature causes not only the value that met the
exception for a parameter to be sent, but also the previous value it was
compared to during the evaluation. The values will be sent with sequential
time stamps. This is a feature that is similar to the OSIsoft Interface and
should be used with caution.
j. Scaling: This setting allows for normal or reverse scaling of each parameter
k. Buffering Mode: This setting enables or disables data buffering and allows
a selection for which medium is used for buffering. Data buffering is where
we store data and timestamps if a connection is not available.
i. To Memory: Buffers data in RAM memory, which is faster, but is
volatile, so if mCore loses power the buffered data will be lost.
