The following topics describe the Data Source fields. For details about<br />

setting up analog, digital, and string tag types, see the Help.<br />

Specifying Device as the data source<br />

An HMI tag with Device as its data source receives its data from a<br />

source external to <strong>RSView</strong>. The data can come from:<br />

• Allen-Bradley ® or SoftLogix 5 programmable controllers through<br />

RSLinx.<br />

• network devices through an OPC or DDE data server.<br />

• another Windows program through an OPC or DDE data server.<br />

For details about creating HMI tags for use with DDE<br />

communications, see Appendix B, Setting up dde communications for<br />

hmi tags.<br />

To create a tag with Device as the data source<br />

1. Click Device.<br />

2. In the Address box, specify the name of the tag in the OPC server,<br />

or specify the DDE item.<br />

You can click the browse button to select the address of the OPC<br />

tag.<br />
