When to Use Symbols?

The use of symbolic names is not mandatory. One exception to this is
communication over PROFInet or communication with a SIMOTION partner. Here
only symbols are used. You can either do without self-defined symbols or add
symbols at a later point in time. If you do not require symbols skip to the next step.

Creating and Using Symbol Files

A symbolic name space is created either directly with NCM PC / STEP 7 or suing
the “Symbol File Configurator” tool.

The Symbol File Configurator program creates a file containing the symbolic
hierarchical name space and the assigned runtime names.

The file created by the Symbol File Configurator is entered in the “Configuration
Console” program.

A symbol file must “fit in” with the configuration loaded on the PC station. To
resolve a symbolic name, the symbol file uses the runtime name. For this reason, if
you modify a connection name in the configuration, you must also adapt the
symbol file to the change. Otherwise the OPC client will not be able to use the
symbol.
