3.2.6 Operation with a Web browser
The 9099 includes a webserver that provides example webpages for the Watlow
F4 and EZ-Zone Temperature Controllers and a general purpose Control page.
The F4 and EZ-Zone were used for the example pages as they are widely used
in environmental test chambers and in industrial processes.
CAUTION - Not all of the example page controls and functions may be
implemented in your chamber or process. Check with your manufacturer
to see which ones are applicable to your chamber or process.
The F4 or Ez-Zone page is reached by clicking on the appropriate button on
the Welcome (index) page. Refreshing the F4 or Ez-Zone page will fetch new
readings from the Temperature controller. Checking a box or entering a value
and 'updating' the page will send the value to the Temperature Controller.
The general Control page is also accessed by clicking a button on the Welcome
page. The Control page provides current ESR and Modbus Error Register
contents so the user can immediately tell if his commands caused an error. Any
of the 9099 commands can be entered in the Device Command textbox and
executed by clicking the Send button. Responses are automatically displayed
in the Device Command window.
The 9099 uses its current Modbus device address value when accessing the
Modbus slave device. The Modbus device address can be set with a web browser
on the 9099 Configuration page or with the Modbus “C" command.
The webserver has access to its Status reporting Structure but does not have a
way to handle Service Requests so the user has to query the Status and ESR
Registers to check for errors if the red ERR LED is illuminated.
3.2.7 Operation from the GPIb bus (9009 Only)
The 9009's GPIB interface is fully IEEE-488.2 compatible and responds to all
of the IEEE-488.2 Common Commands. The GPIB Interface has access to
all of the 9009's SCPI and Modbus commands and to the its Status Reporting
Structure. Service Requests can be used to report 9009 and Modbus errors by
asserting the SRQ line on the GPIB bus. The handling of the Modbus slave
device is the same as described in paragraph 3.2.2.
