LoggeR
Data Logger Manual
The
Logger is a serial data storage device capable of
storing two, four or eight 16-bit values per
record by 16380 records. The logger was designed
to accomodate PLC users who have internal data
that needs to be archived for later analysis. All
timing, and date stamping is determined by the
PLC program. The logger simply stores what it is
sent. The storage capacity represents 56 days of
data at 5 minute intervals, longer or shorter if
the PLC decides so. If the PLC has a real time
clock, the time and date can be formatted and
used to show when the values were recorded (This
takes two 16 bit records to store the time and
date).
A
generic Excel spreadsheet with a serial
communications macro is included to make saving
the archived data easy. Hitting one button on the
sheet will dump all of the saved data directly
into the spreadsheet for further calculation,
analysis, and graphing. Data can also be
retrieved using almost any terminal program, and
saved to a text file.
The
serial Data Logger Module fits into a plastic
channel, which can be mounted directly to a panel
or on a 35mm rail (with the appropriate
brackets). The serial input connects to a serial
port on the PLC, and the serial out connects to a
laptop or other computer when the stored data is
to be retrieved.
