Section 4. Setting up Datalogger Networks
4.2.4.4 Datalogger
Dataloggers have several different tabs. Similar to the serial port, a hardware
tab is completed to specify communications settings. There are also tabs to
define the data to be collected, how often data should be collected, whether to
automatically update the datalogger’s clock, and a tab to send a program. Note
that not all dataloggers will have all the settings described below.
4.2.4.4.1 Hardware Tab
Standard
Communications Enabled – Before communication can take place, all
devices in the chain must be enabled. When this box is selected, the datalogger
is enabled for communication.
Call-back Enabled – Enabling call-back tells LoggerNet to watch for a call-
back from this datalogger. The parent PakBus port will be set up to receive
incoming calls.
The communication port (i.e., the root device) must be configured for call-back
as well. Enable the root device’s Call-Back Enabled check box to accomplish
this.
Maximum Time On-Line – This field is used to define a time limit for
maintaining a connection to the device. (This may be useful in avoiding costly
communication costs, in the event that a connection to a station is inadvertently
maintained for a long period of time.) Maximum Time On-Line applies to both
scheduled connections and manual connections. However, for manual
connections from the Connect Screen, it is always best to manually disconnect
rather than relying on LoggerNet to disconnect for you.
When the device is contacted on a schedule, communication with the device
will be terminated once this time limit is exceeded. A value of 0 in this field
indicates that there is no time limit on maintaining a connection to the device.
When the device is connected in the Connect Screen and the time limit
approaches, a dialog box is displayed warning the user that Max Time On-Line
is about to be exceeded. The dialog box has
Reset Max Time and Don’t Reset
buttons. If the Reset Max Time button is pressed, the Max Time On-Line
counter will be reset. If the Don’t Reset button is pressed or if no button is
pressed, the connection will be terminated when Max Time On-Line is
reached.
The format for this field is 00 h(ours) 00 m(inutes) 00 s(econds).
