ERASE operation:
• If the position is empty, an error message is displayed.
• If the position is in use, confirm that the existing data is to be
permanently erased before doing so.
SEND operation:
• If the position is empty, an error message is displayed.
• If the position is in use, send the data to the RS232 port in a
report format.
6.10.2 Data Log
Process data may be stored for a single tag for later upload to a
personal computer via the BetaLOG HART Windows application.
We recommend that you use PN: 1920049 (Lemo to USB Cable) for
use with the BetaLOG HART Software . It incorporates a USB/Serial
adapter using an FTDI chipset. This combination provides consistent
and reliable communications between the LC-110H and PC. The
USB Drivers are included on the BetaLOG HART Software CD.
Data may be logged in multiple sessions, but all sessions must be
from the same HART device as determined by the long tag name. A
different logging interval may be selected for each session. Each
data sample contains the LC-110H measurement, device mA, and all
four process variables.
The data logging capacity is 9810 records less 2 overhead records
for each session. The number of sessions is limited to 99.
Records free: 9810 ♥

Battery: 7.6 V
The ♥ symbol in the upper right corner flashes to indicate a working
HART connection.
The number of free records is shown on the first line. If data has
already been logged, the tag number is shown below it.
The present battery voltage is displayed at the bottom to allow the
user to decide whether the batteries should be changed before
starting the log. The log is stopped before the LC-110H is turned off
when the battery reaches its low voltage automatic shutoff limit of 5.6
volts.
