Property Tags

Tag Properties are available as additional tags that can be accessed by any Data Access client by appending the
property name to any fully qualified tag address. When using an OPC client that supports item browsing, users can
browse tag properties by turning on Include tag properties when a client browses the server under OPC
Settings. See Also:

Statistics Tags

Statistics Tags are used to provide feedback to client applications regarding the operation of the channel
communications in the server. When diagnostics are enabled, there are seven built-in statistics tags available. See

Automatic OPC Tag Database Generation

This server's Automatic OPC Tag Database Generation features have been designed to make setting up the OPC
application a plug and play operation. Communications drivers that support this feature can be configured to
automatically build a list of OPC tags within the server that correspond to device-specific data. The automatically
generated OPC tags can then be browsed from the OPC client. The OPC tags that are generated depend on the nature
of the supporting driver.

If the target device supports its own local tag database, the driver will read the device's tag information and then use
the data to generate OPC tags within the server. If the device does not natively support its own named tags, the driver
will create a list of tags based on driver-specific information. An example of these two conditions is as follows:

1. If a data acquisition system supports its own local tag database, the communications driver will use the tag

names found in the device to build the server's OPC tags.

2. If an Ethernet I/O system supports detection of its own available I/O module types, the communications driver

will automatically generate OPC tags in the server that are based on the types of I/O modules plugged into the
Ethernet I/O rack.

Automatic tag database generation's mode of operation is completely configurable. Parameters set in the following
dialog allows users to configure how the server and its associated communications driver will handle automatic OPC tag
database generation.


The Automatic tag database generation on device startup setting is used to configure when OPC tags will be
