PRODUCT SETUP
An ObjectReference to the data set, which consists of the concatenation of the string "<LDName>/LLN0$" and the data
set name, is used in the datSet field of report messages, and it can be used by the client to discriminate Unbuffered
Report1 messages from other messages.
The performance of the report is determined by the performance of the selected dataset. When the selection is
TT3DataSet01, TT3DataSet02, ... it is possible that transient events can be missed.
Unbuffered Report1 ConfRev
Range: 0 to 4294967295 in steps of 1
Default: 1
The entered value sets the confRev value in Unbuffered Report1 messages, and it can be used by clients to discriminate
report messages of the expected configuration revision from messages of a different revision. The standard requires
that confRev be incremented each time the members or the order of the members is changed, and each time the data
set name is changed. The standard states that the value of 0 is reserved.
Unbuffered Report1 OptFlds
Range: The check box for an individual bit can be enabled or not
Default: All bits enabled / true
The OptFlds setting is bitstring that controls which of the optional fields are included in report messages. The options are
as follows. To reduce message size, uncheck any fields that are not needed.
– sequence-number
– report-time-stamp
– reason-for-inclusion
– data-set-name
– data-reference
5
– conf-revision
The OptFlds bits buffer-overflow and entryID also listed are not applicable to unbuffered reports even though the bits
exist in the protocol. They are unchecked by default.
Unbuffered Report1 BufTm
Range: 0 to 4294967295 in steps of 1
Default: 0 ms
The entered value sets the time interval in milliseconds for the buffering of events for inclusion into a single report.
Unbuffered Report1 TrgOps
Range: The check box for an individual bit can be enabled or not
Default: All bits enabled / true
The TrgOps setting is bitstring that controls which trigger conditions are monitored in this report. The options are as
follows. Uncheck any trigger conditions that are not needed.
– data-change
– quality-change
– integrity
– general interrogation
Unbuffered Report1 IntgPd
Range: 0 to 4294967295 in steps of 1
Default: 0 ms
The entered value sets the period in milliseconds for generating Unbuffered Report1 integrity reports. An integrity report
includes the values of all members of the referenced data set, whether a change has occurred or not.
