Section 11. Utilities Installed with LoggerNet Admin and LoggerNet Remote

Once the data tables to be exported are specified, the user selects an output

socket port and the export utility will begin “listening” for a request from a

remote application to send data. When the connection to the application is

established, data export is initiated.

The options that determine the operation of Data Export are set from the dialog

box opened from Data Export’s Edit | Options menu item. There are five

options as described below:

Listening Port Number – The Listening Port Number is the port number that

Data Export will monitor for a request for data. The default port number is

1200; this can be changed to any valid four-digit port number.

Starting Options – There are two options for choosing what should be the first

record exported when data export is first started. If the

Get All Data option is

chosen, Data Export will attempt to export all available data from the data

cache for the specified datalogger tables.

When Start with Newest Record is

chosen, export will begin with the most recent record. In this instance, no

historical data will be exported from the data cache. Note that this setting

applies only to the first time data export is initiated for a table. Subsequent data

export sessions will begin exporting after the last known exported record.

Collection Options –Holes are discontinuities in data that is being collected

via data advise. There are two options for Data Export behavior when a hole is

encountered. If

Wait for Any Holes is selected Data Export will wait until data

holes are filled or become uncollectible before exporting the next record. Thus,

the utility attempts to export data in record order. If

Collected Order is

selected, Data Export will export records as they are collected by the

LoggerNet server. With this option, it is possible that data records are exported

out of order.

Data Format – This is the format in which the data should be exported. If the

RTMS Format option is selected, the data is formatted to be received by an

RTMS compatible computer. RTMS (real-time monitoring software) is a

format developed by CSI for communication between OS/2 operating systems

and table-based dataloggers. If

Standard Format is selected, the data is

formatted as an ASCII comma separated record format that includes header

information. The protocols for both formats are described in later in this

section.

Resending Options – If a message is exported and there is no response or an

incorrect response is received from the remote application, Data Export will

resend the data. The Resending options are used to set the time interval on

which the data will be resent

(Time to Wait before Resending the Data) and

the number of times Data Export will attempt to send the data and receive a

valid response (

Number of times to Resend the Data).

You can run multiple instances of the Data Export application by specifying a

different initialization directory for each instance. This is done by adding the

directory information to the command line of the shortcut that starts the

application. An example of this command line would be:

c:\Program Files\…\SocketDataExport.exe directory pathname
