PakBus Over TCP/IP and Callback, 8.2.2 Default HTTP Web Server

Page 168 highlights

Section 7. Installation • DHCP client to obtain an IP address • DNS client to query a DNS server to map a name into an IP address • SMTP to send email messages 7.8.2.1 PakBus Over TCP/IP and Callback Once the hardware has been configured, basic PakBus® communication over TCP/IP is possible. These functions include sending and retrieving programs, setting the CR800 clock, collecting data, and displaying at the most current record from the CR800 data tables. Data callback and datalogger-to-datalogger communications are also possible over TCP/IP. For details and example programs for callback and datalogger-todatalogger communications, see the network-link manual. A listing of networklink model numbers is found in the appendix Network Links (p. 545). 7.8.2.2 Default HTTP Web Server The CR800 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. 169), 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 CR800 drives. To copy files to these drives, choose File Control from the support software menu. 168

DHCP client to obtain an IP address
DNS client to query a DNS server to map a name into an IP address
SMTP to send email messages
7.8.2.1 PakBus Over TCP/IP and Callback
Once the hardware has been configured, basic PakBus
®
communication over
TCP/IP is possible. These functions include sending and retrieving programs,
setting the CR800 clock, collecting data, and displaying at the most current record
from the CR800 data tables.
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. 545).
7.8.2.2 Default HTTP Web Server
The CR800 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. 169),
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 CR800 drives.
To copy files to these drives, choose
File Control
from the support software
menu.
