I am using my PLC, which supports the OPCUA Transfer Subscription service, along with Ignition Client as the OPCUA client. I want to trigger a Transfer Subscription request from one session to another session. Can anyone provide guidance on how to achieve this?
You cannot. Subscriptions are transferred if the connection is lost and a new session is subsequently established. Otherwise there is no way or need to transfer subscriptions.
Does that mean the server automatically transfers the subscription to the new session?
The Client initiates the transfer after reconnecting, not the Server.
So if I am using induction client then how to send transfer request ?
You don’t, it happens automatically when the client reconnects after a connection loss. You can’t trigger it on your own.
