globelog Logger V 1.0
2 Overview
Your globeLog has the following memory:

Data memory (“Flash”), 2 MB (for upto approximately 400,000 readings).
The Flash memory has a large memory capacity which, from the point of view of the user, is the most
important feature: it contains all the retrieved readings.
Your globeLog has been built and designed with the basic principles of reliability and stability in
mind. This is partly reflected in the fact that all the memory areas are designed in such a way that
your readings cannot be lost even in the case of a sudden loss of power. As soon as the power supply is restored to your logger it will resume operation operation without any loss of data and without
having to be reconfigured.
Another basic principle behind your globeLog is the integrity of the stored readings. Volatile data
memories are very sensitive to external influences such as radiation, lightning strikes, moisture, and
interference peaks. This is why we have kept this memory area as small as possible. In “sleep” mode
only the RTC uses a small volatile memory area as a counter. The RTC is constructed so as to ensure
that if data is lost it will resume operation automatically within a maximum of a few hours. The RTC
has a small independent battery that supplies enough power for a few years.
Years of experience and testing have gone into the technology and components used to construct
your globeLog, which makes this device a very reliable feature of your sensor network, even in the
most extreme conditions. Compared with a modern computer, your globeLog has an unbelievably
little memory but is still capable of performing complex calculations, managing its power supply very
efficiently, and even controlling a GPRS modem for the purposes of allowing a totally wireless transmission of the measurement data. In addition to this it also monitors its functions continuously by
means of processes that run in the background (so-called “Watchdogs”) to ensure the safety of the
readings under all circumstances.
In order to make your globeLog as robust as possible, however, we have had to forfeit a certain degree of technical sophistication. For example, your logger cannot process several tasks simultaneously. Your logger is a so-called “single-task system”, in other words this means that the user might
find that from time to time the logger might appear to not respond immediately when running the
globeLog Control software. If this occurs, simply wait a moment and then try again.

18.
The parameter dialogue is divided into three areas: “Global Parameters” (1), “Sensor
Power and Bus Settings” (2), and (3) in which the SM modules and channel configuration can
be changed and transferred to the logger.
19.
The “Global Parameters” area (1) contains the following setting options:

Period: frequency of the measurements. In the example, every 10 minutes, starting at
00.00 (midnight).

Period Offset: shifts the starting time forward from 00.00. A figure of 3 min
combined with a period of 6h, for example, would mean that your globeLog would
take measurements at 00.03 a.m., 06.03 a.m., 12.03 p.m. and 18.03 p.m.

Name: name of your globeLog.

Clock Adjust (sec): adjusts your globeLog’s time.

HK-Counter: this figure determines how often the HK (house-keeping) parameters of
your globeLog are to be saved along with the readings. A figure of 6, as shown in
the example above, means that with every sixth measurement cycle the HK
paramerters are saved as well.

Log HK: here you can specify which HK parameters are to be measured.

Parameter Set: ID string of the current configuration.

Internet GPRS: see section “GPRS configuration”.
The “Sensor Power and Bus Settings” area (2) contains the following setting options:

Power Up Wait (msec): the time that your globeLog waits for the measurement bus
after the power has been switched on before giving the connected modules and
sensors the command to measure. The reason for this is that every module and every
sensor requires a little time for initialisation.

Mode: serial or parallel communication with the probes. Parallel communication up
to a maximum of 3 modules on the measurement bus. Serial operation is
recommended.

Sensor Min/Max (sec): minimum/maximum time in seconds after switching on the bus
before your globeLog sends the command to the modules to commence measuring.
21.
Area (3) contains the buttons to access the configuration of the SM module and
sensor channels and to transfer the altered configuration to your globeLog. More details can
be found in the section “Configuring the SM module and and sensor channels”.
