Data logging
The data logging feature allows you to record the status of I/O
registers on a regular basis. Data is saved to non-volatile memory,
and can be retrieved at a later time. You can enable data logging
on 215U-2 version 2.0 modules with the purchase of a feature key
license (see “Feature license keys” on
page 31
).
Data is logged to an internal data file in “.csv” format. Each row of
the file is a single record, consisting of a timestamp and values of
all of the configured log items at that time. When the file reaches a
configured maximum number of rows, the file is “rolled,” that is, the
file is compressed and archived and a new log file is created.
The amount of memory available for storing logged data depends
on the device type. The available data logging memory is indicated
in the log files. When the memory is full, the oldest data log file is
deleted.

You need Administrator or Manager privileges to configure data and
event logging.
Figure 45. Data and event logging configuration
Data log configuration
The configuration example in see
Figure 47
will log six registers in
each log record.
Table 20
shows an example of the logged data for
this configuration.
Scan Rate
Enter the rate that you want data to
be recorded (fastest rate is every 5
seconds).
Records per File
Enter the maximum number of records
you want in a file (up to 3,000 records
per file). When the maximum is
reached, the file is archived and a new
data log file is created.
Data Log Record
Each entry in this table specifies a
block of registers to be included in the
log. To add an entry, click Add Entry
and fill in the Name, First Register, and
Count information. Select the Enable
checkbox to enable data logging for
the block. You can configure up to 100
register blocks. Use Delete to remove
an entry that you no longer want.
For a configuration example, see
Figure 47
and
Table 20
.
Enable
When this checkbox is selected,
data logging is enabled for this block
of registers. When it is cleared, a
placeholder symbol “-” is stored to the
log file.
Name
Name to appear in the column heading
within the log file to identify data for
this entry. If no name is entered, the
register number is used as the column
heading.
First Register
Address of the first register to be
logged.
Count
Number of registers to be logged.
Event Log Configuration
These settings apply only to modules
that have the 915U-AT (Audit Trail)
feature key enabled. Event Logging is
discussed in a separate document.
