Logging

Lynx can save site data directly to your computer and
store it in a database for use in reports. This is called
Logging, and it allows you to generate detailed reports
using the Report Writer. For more on logging, see Chapter
7.

Lynx can log site information in two different ways, which
may be used simultaneously or independently:

To set up your logging preferences:

1. If logging is desired, check the E

2. Choose a logging method:

nxx.. This is the simplest and most efficient way to log your site data, and it is

especially beneficial when you use a full-time PC connection the remote site. Real-time information is
taken from the I/O units and saved to the Lynx database at the interval specified. This method requires
that Lynx is running on your computer at the time of the log in order for the information to be saved at
the correct time. If Lynx is running, but you are not already connected, Lynx will automatically establish a
connection at the specified logging time, take the log, and disconnect when finished. You will be prompted
before Lynx disconnects from one site to log another site (for unattended operation, this prompt can be
disabled from the W

time, it will continue to retry the connection until a successful connection is made.

nxx.. The advantage to logging with onboard captures is that you

may not need to connect to the remote site as frequently to download the same volume of data as
logging directly. This may be significant if you are using a dial-up modem that requires a toll call to
connect, or the phone line is in high demand for other purposes. With this method, Lynx will download
captures already stored in the I/O unit’s memory and store the information in the database. To make use
of this method, set up a capture schedule as part of the I/O unit’s Timed Events configuration (see page
34), and coordinate the logging interval to download those captures as frequently or infrequently as
practical. For example, you could program each I/O unit to take a capture every hour, and set the logging
interval to download those captures only once or twice a day.

IIM

T!! Each unit can hold a maximum of 192 captures. Once this capacity is reached, the unit will

completely clear its capture buffer before storing additional captures. To avoid losing capture data before your
computer downloads it, check C

Clleea

arr C

pttuurree Q

Quueeuuee a

afftteerr d

nllo

diin

ngg to permanently erase the captures from the

unit after Lynx saves the data.

Note: Logging using captures relies on captures already stored on the unit; it will not actually take new captures. You
have to separately set up captures to occur as timed events (see page 39).

3. In the interval field, specify how often Lynx should take data for the log (in hours or minutes). Then assign

the time at which you would like the next log to take place. This affects the “log offset.” For example: if
you specify hourly logging and set the Next Log time to 2:15, the next log will occur at 2:15, and
subsequent logs will be taken at fifteen minutes past each hour. When logging multiple sites, you may wish
to stagger the Next Log times when you set up each site.

4. Click Next. The Site Wizard will confirm that you have successfully set up the site in Lynx.
