8.6.3.1 PakBus Over TCP/IP and Callback
Once the hardware has been configured, basic PakBus
®
communication over
TCP/IP is possible. These functions include the following:
• Sending programs
• Retrieving programs
• Setting the CR1000 clock
• Collecting data
• Displaying the current record in a data table
Data callback and datalogger-to-datalogger communications are also possible over
TCP/IP. For details and example programs for callback and datalogger-to-
datalogger communications, see the network-link manual. A listing of network-
link model numbers is found in the appendix Network Links
(p. 652).
8.6.3.2 Default HTTP Web Server
The CR1000 has a default home page built into the operating system. The home
page can be accessed using the following URL:
http:\\ipaddress:80
Note Port 80 is implied if the port is not otherwise specified.
As shown in the figure, Preconfigured HTML Home Page (p. 291), this page
provides links to the newest record in all tables, including the Status table, Public
table, and data tables. Links are also provided for the last 24 records in each data
table. If fewer than 24 records have been stored in a data table, the link will
display all data in that table.
Newest-Record links refresh automatically every 10 seconds. Last 24-Records
link must be manually refreshed to see new data. Links will also be created
automatically for any HTML, XML, and JPEG files found on the CR1000 drives.
To copy files to these drives, choose File Control from the datalogger support
software
(p. 512) menu.
