opchdaserverinfo

Query host for installed HDA servers

Description

S = opchdaserverinfo('HostName') queries the host named HostName for the OPC HDA servers installed on that host. 'HostName' can be a host name, or IP address, specified as a character vector or string.

S is returned as a vector of OPC HDA ServerInfo objects, containing the following read-only properties.

Property Name	Description
Host	The host name passed to getServerInfo
ServerID	The programmatic Server ID to use when constructing an HDA Client object associated with the server
Description	A text description of the server
HDASpecification	A character vector denoting the HDA specification supported. Currently, only 'HDA1' is returned in this property.

Using the ServerInfo objects in S, you can find a particular server based on the Description property using findDescription(S,'StartText'), or you can construct a client by passing the relevant element of S to the opchda function.

Examples

Find a list of HDA servers on the local host.

sInfo = opchdaserverinfo('localhost');

Locate the specific server with a description containing the character vector 'Matrikon'.

mIndex = findDescription(sInfo,'Matrikon')

Construct an OPC HDA client for that server.

hdaClient = opchda(sInfo(mIndex))
