Types of data servers<br />

In <strong>RSView</strong> <strong>Supervisory</strong> <strong>Edition</strong> , you can create two kinds of data<br />

servers:<br />

• an OPC data server.<br />

• an RSLinx Enterprise data server.<br />

If you are using RSLinx for <strong>RSView</strong>, RSLinx Gateway, or a third-party<br />

OPC data server for communications, create an OPC data server.<br />

RSLinx Gateway, or any data server that conforms to the OPC-DA 2.0<br />

standard. RSLinx for <strong>RSView</strong> and RSLinx Gateway provide enhanced<br />
