4.1.2.2
Output type
Per output driver you can specify which type of data you want to output: 1) All logged data since the previous
successful transmission, 2) Just the last know sampled actual values or 3) a heartbeat message.
The primary output is normally chosen for transmission of the logged data.
A heartbeat can be used to indicate thru an alternate output that a system is still a live or to have an entry
point in time to do a remote configuration if not possible thru the primary output (see: chapters remote
configuration).
4.1.2.3
Data format
This defines the data format of the transmitted content/file. This can be our native TXT format, JSON or a
CSV (comma separated value) format which can easily be picked up by third party applications like
Microsoft Excel. The column order of the CSV file, follows the order of the parameter list (see: chapter
“Parameter overview”) . We prefer native or JSON format as it can contain data as well is diagnostic info.
4.1.2.4
Data filter
The logger records Log Data (measurements) as well as system Diagnostics. With a data filter you can
specify which you want (or both) to include in the transmission.
4.1.2.5
Max payload
In circumstances like a network outage a data log file will grow bigger and bigger and depending on the
application to several megabytes or more. If the payload becomes bigger than 1MB the logger will chop
the transmission up in several parts. In areas with unstable coverage you can trim down the maximum
payload setting to an appropriate value.
4.2 Parameters
All through the configuration-settings of the data logger, you will encounter parameters to setup your
logger. They are used on all ports (analog, digital, serial) and are generic in use. This section describes
the use and properties of parameters. Below a screenshot of some parameter-settings are shown.
