Section 4. Setting up Datalogger Networks
To add a terminal server to the pool, type in the address of the terminal server
port in the Terminal Server field and press the Add button. The address
consists of an IP or DNS address followed by a colon followed by the TCP port
number (e.g., 192.168.7.14:10001 or
[2620:24:8080:8600:85a1:fcf2:2172:11bf]:10001). After the terminal server
has been added to the pool, there will be check box next to it in the Terminal
Server Pool box. Select this check box to use serial control protocol (RFC
2217).
To delete a terminal server from the pool, select it in the Terminal Server Pool
box and press Remove.
When a TerminalServerPool is added, LoggerNet will search for
other TerminalServerPools in the network map and add all of the
terminal servers specified in the existing TerminalServerPools to
the new TerminalServerPool.
4.2.5 Setting Up Scheduled Data Collection
4.2.5.1 Data Collection Scheduling Considerations
One of the goals in datalogging applications is to retrieve the data from the
datalogger’s memory to a computer so that it can be analyzed further.
LoggerNet can be used to retrieve the data from the datalogger manually, on
demand, or you can set up an automatic data collection schedule. When the
schedule is enabled and LoggerNet is up and running, the LoggerNet server
will initiate calls to the datalogger on the defined schedule and collect its data.
Remember that what data is collected, and how it is stored, is configured on the
datalogger’s Data Files or Final Storage Area tab. When the data is collected,
it is stored to a file (unless the No File option is chosen when setting up what
data to collect), and it is also stored in LoggerNet’s data cache. LoggerNet
client applications, such as the Numeric and Graphical Displays or RTMC,
retrieve their information from this data cache.
In some cases, LoggerNet client applications display only data that has been
collected. In other cases, LoggerNet initiates the retrieval of data to display.
These cases are described below:
Numeric Displays and Graphs (opened from the Connect Screen)
Mixed Array Dataloggers
Final storage data from mixed array dataloggers is retrieved only when
data collection from the datalogger occurs (initiated manually from the
Connect Screen or based on a schedule). Therefore, the final storage
information on the data displays will be updated only as often as data
collection is performed for these dataloggers. Input locations do not have
to be scheduled for collection to be displayed. When connected, these
values are updated based on the update interval of the display (but limited
by how fast measurements are actually being made in the datalogger).
