Appendix G: The automated test equipment (ATE) interface
OUI control in MATLAB The OM4000 OUI software communicates with other programs via port 9200 on
the computer running the OUI software.
NOTE.
Ensure that the OUI is running before using this interface.
To get an up-to-date listing of methods for the OUI basic service type the
following: methods(obj) MATLAB should return the same functions (See
page 168,
OUI control in MATLAB .) and any new functions that have been added.
These functions are self-documented when they are generated.
By enabling the MATLAB help window, you can fi nd out the function’s
parameters by typing the function name followed by a “(“ and waiting for the
help to pop up.
Initialize the interface in the MATLAB desktop command window with the
following commands:
url = 'http://localhost:9200/Optametra/OM4006/
WCFServiceOM4006Basic/?wsdl';
createClassFromWsdl(Url);
obj = WCFServiceOM4006Basic;
Where:
The fi rst speci fi es the URL or path to a WSDL application programming interface
(API) that de fi nes the web service methods, arguments, and transactions for the
OUI web service.
The second creates the new class based upon that API and builds a series of
M-Files for accessing the OUI basic service.
The third instantiates the object class name and opens a connection to the OUI
basic service.
These commands only need to be run anytime the service interface (available
methods) changes.
To get an up-to-date listing of methods for the service, type the following:
methods(obj)
Matlab should return the same functions (See page 168, OUI control in MATLAB .)
and any new functions that have been added. These functions are self-documented
when they are generated. By enabling the MATLAB help window, you can
fi nd
out the function’s parameters by typing the function name followed by a “(“ and
waiting for the help to display.
