Naming rules

When entering data references for an I/O attribute in Application Server, the following naming rules are used to create or rename points in the Telemetry Server:

• If a point with the specified name and address does not exist in the specified group and outstation, a new point is created with specified name. If a point name is not specified in the reference, the default naming convention is used to generate the point name. Typically, this is <PointType>_<Address>.

• If the point name is specified in the data reference, the point name must be enclosed in square brackets [ ].

• If a point with the specified name and address already exists in the specified group and outstation, the existing point is used.

• If a point with the specified address but a different name is found in the specified group and outstation, the reference generates a configuration error. The point with specified address is not changed and a new point is not created. See Configuration errors for more information.

• If a point with the specified name exists in the specified group, but is attached to a different outstation, the reference generates a configuration error. The named point is not changed and a new point is not created. See Configuration errors for more information.

• If a point with the specified name exists in the specified group and outstation but has a different point address, the reference generates a configuration error. The named point is not changed and a new point is not created. See Configuration errors for more information.

• If any other database object with the specified name exists in the specified group, the reference generates a configuration error. A new point is not created. See Configuration errors for more information.

• If the point name is invalid, for example, if it contains invalid characters, is too long, or has some other error, the reference generates a configuration error and a new point is not created. See Configuration errors for more information.
