get

OPC Toolbox object properties

Syntax

Val = get(Obj,'PropName')
get(Obj)
Val = get(Obj)

Description

Val = get(Obj,'PropName') returns the value Val of the property specified by PropName for the OPC Toolbox™ object Obj.

If PropName is a cell array of character vectors containing property names, get returns a 1-by-N cell array of values, where N is the length of PropName. If Obj is a vector of toolbox objects, Val is an M-by-N cell array of property values where M is equal to the length of Obj and N is equal to the number of properties requested.

get(Obj) displays all property names and their current values for the toolbox object Obj.

Val = get(Obj) returns a structure, Val, where each field name is the name of a property of Obj containing the value of that property. If Obj is an array of toolbox objects, Val is an M-by-1 structure array.

Examples

Obtain the values of the Status and Group properties of an opcda object, and then display all the properties of the object:

da = opcda('localhost','Dummy.Server'); 
get(da, {'Status','Group'}) 
out = get(da,'Status') 
get(da)

Tips

As an alternative to the get function, you can directly retrieve property values using dot-notation. The following two lines achieve the same result.

t = get(daObj,'Timeout');
t = daObj.Timeout;
