Namespace: OSIsoft.AF.PI
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182
Syntax
public void SwitchMember( PICollectiveMember member )
Public Sub SwitchMember ( member As PICollectiveMember ) Dim instance As PICollective Dim member As PICollectiveMember instance.SwitchMember(member)
public: void SwitchMember( PICollectiveMember^ member )
member SwitchMember : member : PICollectiveMember -> unit
Parameters
- member
- Type: OSIsoft.AF.PIPICollectiveMember
The preferred member of the PICollective selected for the connection. If the member is not available, then the connection will failover to another member.
Remarks
This method will change the currently connected member of the collective to the specified member if the current Priority settings allow a connection to this member. This method will not modify the current failover behavior of the PICollective established with the initial connection to the collective.
A direct connection can be made to a collective member using one of the PICollectiveMember.Connect Overload methods. If the current connection to a collective member is a direct connection, then this method will establish a normal failover connection before switching members.
