9.4 STANDARD DATALOG
The standard datalog format allows up to 16 Status Display Module (SDT) datapoints and 24 Pa-
rameter Module (PAR) datapoints to be logged. The number of SDT datapoints to be included in
the datalog is specified by the value of datapoint B328 (maximum is 16, one for each SDT data-
point in the standard datalog). The number of PAR datapoints to be included in the datalog is
specified by the value of datapoint B329 (maximum is 24, one for each datapoint pair). The se-
lected SDT datapoints are configured by the user for status indicator display attributes and so are
the selected PAR datapoints, which are configured to access the values from specified point loca-
tions.
The general format of the standard datalog is illustrated in Figure 9-2. It is divided into three sec-
tions: header, status block, and parameter block. The first line of the standard datalog has the
header, which contains the Unit Tag Name, Time, and Date. The month for the date is entered as
a numeric value from 1 to 12. The status block follows the header and it contains information de-
rived from the SDT modules’ Name, State, Mode, and Alarm Enable values. Each line in this block
contains up to four SDT entries which are allocated in the following order: SDT1.8 NAME, SDT1.7
NAME, . . . SDT0.1 NAME. The parameter block appears in the standard datalog after the status
block. It contains information derived from the PAR modules. Each line in this block contains up
to two PAR entries which are allocated as follows: PAR7.3 NAME, PAR7.3 DESIGNATOR,
PAR7.2 NAME, PAR7.2 DESIGNATOR, . . . PAR0.1 NAME, PAR0.1 DESIGNATOR.
The value configured into datapoint B330 selects the channel to which the standard datalog is di-
rected. If a 4 is entered into datapoint B330, then the standard datalog is directed out of DDI-A. If
a 3 is entered into datapoint B330, then the standard datalog is directed out of DDI-B.
Datapoints B328 through B330 can be summarized as follows:
Datapoint Standard Datalog Function
B328 Determines the number of SDT datapoints presented in the datalog
(maximum is 16).
B329 Determines the number of PAR datapoints (datapoint pairs) presented in
the datalog (maximum is 24).
B330 Determines the output channel: 4 = DDI-A, 3 = DDI-B.
A standard datalog configuration and printout example are given in Figure 9-3.
