Unregister SWAP Assets

There are several ways to unregister SWAP Assets within the Registry Module: - Remove Agent Method within the Registry Module - Unregister Method from the Common Information Model (the method callback is provided within the open62541-server-template) - Json Configuration of the open62541-server-template. However, this approach automatically unregisters the agent when shutting down the server, so that no code example will be provided. The code example is available at Registration. The server must just be shut down for the un-registration.

First, the Registry Module must be started:

/*build and start the registry module*/
git clone https://github.com/FraunhoferIOSB/swap-it-registry-module
cd swap-it-registry-module
mkdir build && cd build
cmake ..
make
./swap-it-registry-module

as well as a swap-asset, which registers itself:

cd build
./tutorials/unregister

Unregistering with the Remove Agent Method

First the asset can be removed from the registry module with the remove agent method inside the registry module:

The Method requires three arguments:

agent_url: the web-address of the server

agent_port: the port of the server

service_name: Name of the Service offered from the server

Now, its possible to set the values and execute the method:

agent_url: localhost

agent_port: 4840

service_name: GetPartsFromWarehouse

Finally, the server is removed from the registry module:

Unregistering with the unregister Method

Similar to the registering approach, assets can be removed as well from the server side. Here, the open62541-server-template provides a corresponding unregister method callback,

The method requires the following arguments:

The Method requires two arguments:

Registry URL: URL of the registry module

Resource URL: URL of the server

Both arguments can be set with:

Registry URL: localhost:8000

Resource URL: localhost:4840

Finally, the server is removed from the registry module:
