Remote control OPC ip address

Question

I am new with OPC UA world and I need to getting start with this. I have a company in witch there is a new machinery that is an opc server. This machinery is actually linked in internet with dhcp. In particular, I need to understand:

For remote control on the same network I only need to take the ip address (eventually static) and I can monitor and write values of the server, is this right?

Answer 1

OPC UA server provide different endpoints, typically in the form of opc.tcp://myOPCUAServer:12345/path those endpoints can be discovered using the local IP address or DNS name. Your OPC UA stack typically provide functionality to list all the endpoints, like DiscoveryClient.GetEndpoints() and than select one for you CoreClientUtils.SelectEndpoint() .

Often endpoint support different connection settings like Security Policy (eg Basic256Sha256), Message Security Mode (eg SignAndEncrypt) and User Authentication (Anonymous, Username/Password, Certificate). Your client connection would need to support the same, in order to connect.
