$ java -jar target/opcua-server-0.0.1-SNAPSHOT-jar-with-dependencies.jar

server_1


 start : start opcua server / create Node  -> first of all, you should input this command for testing

 getnode : get node information

 getnode2 : get node information with browse name

 quit : terminate server

 help : show menu
  • client
$ java -jar target/opcua-server-0.0.1-SNAPSHOT-jar-with-dependencies.jar

client_1


   start : start opcua client / connect with opcua server / intialize Service Provider

   quit : terminate client

   provider : get the provider list

   browse : browse all nodes with root node

   browse_m : multiple browse with several target nodes

   read_s : read attribute for server node

   read_t : read attribute for target node

   read_gp : multiple read attribute for target nodes

   write : write attribute to target node

   write_gp : multiple write attributes to nodes

   sub : subscription 

   sub_modify : modfiy subscription

   sub_delete : delete subscription

   endpoint : get endpoints from the server

   auto : run test automatically

   help : show menu

input start CNC in OPC-UA Server.
Then update value of the 'cnc100' node server_8

input sub command in OPC-UA Client. And then, input the alias of the provider which indicate target node.
Then request subscription to target node. you can receive changed value from the target node. client_7 client_8
