Reference

Setting the tags configured on the CPU in the "Properties > General > Tag declaration" parameter group.

Meaning of the tag declaration

To access tags of the CPU using a Web browser and Java applet, the CP must be aware of the names, addresses, and access rights of these tags.

In the symbol list in the tag declaration, you can see the currently known tags with their symbolic names, the corresponding operands and the assigned access rights.
