Data Logging and Communications Set up
Data logging facilities are a standard in all
“C” series controllers, and with the Data Log
interval set to 30 mins - over 4 weeks of data
logged on a 24/7 basis, can be stored before it
is over written. See Set Data Logger Screen on
page 15.
Down loading the Data Log
The data in the data log can be retrieved in a
numbers of ways namely -
1. The data log can be down loaded locally to
a laptop using the
Free
HyperTerminal pro-
gram available in Microsoft Windows pro
-
gram, via a Serial cable attached to a laptop
and to the DB9 connector fitted internally in
the controller.
2. If a GSM modem and a SIM data card have
been fitted, the data log can be retrieved re
-
motely by again using HyperTerminal.
Both of these methods retrieve the data log in text
format which will need further importation into an
Excel spreadsheet for trending and graphing for
reporting means.
3. Using AquaGuard 2 (30 day trial version) or
AquaGuard 2 + Activation Key, allow for the
data to be download into a database and with
direct importation into an Excel spreadsheet
- CWT_Graphs.xlt template to automate the
graphing, summary, and trending charts, and
speed up reporting. Use of a serial cable
and a laptop allows for local download as in
No. 1 above.
4. Where a GSM modem with a SIM data card
has been fitted - full remote control is avail
-
able using AquaGuard 2 software as in 3
above, plus alarms to 3 phones, and remote
start up of disinfection, or changes to set
points - all from the PC or laptop in your of-
