removepublicgroup - Remove public group from server
Syntax
removepublicgroup(DAObj,'PublicGroupName')
Description
removepublicgroup(DAObj,'PublicGroupName') removes
the public group PublicGroupName from the server
that DAObj is connected to. DAObj must
be a connected opcda object.
If the public group has clients using that group, removepublicgroup issues
a warning; then it removes the group from the server only when all
clients have stopped using that group. No additional clients can connect
to that group after you call removepublicgroup.
Not all OPC data access servers support public groups. If you
try to make a public group on a server that does not support public
groups, you get an error. To verify that a server supports
public groups, use the opcserverinfo function
on the client connected to that server: Look for an entry 'IOPCPublicGroups' in
the 'SupportedInterfaces' field.
Examples
Connect to the server Dummy.Server and remove
the public group named PGroup:
da = opcda('localhost', 'Dummy.Server');
connect(da);
removepublicgroup(da, 'PGroup');
