OPC Client RDI Configuration

1 OPC Client RDI Configuration Tool

OPC is the industry standard method of obtaining data for commercial enterprise consumption from all

kinds of process control devices. The OPC Client
as part of an OpenEnterprise session, and is able to make use of any OPC Server conforming to OPC
Data Access 1.0a and 2.0x standards to collect signal data. The OPC Client RDI configuration tool
provides the SCADA engineer with a simple and intuitive way to configure the OPC Client RDI
component.

Additionally, the configuration tool is able to take a snapshot of the current OPC Client RDI
configuration from within an OpenEnterprise Database, and export this to an SQL script file which can
in return be imported in order to rebuild the database contents at a later date. The OPC Client RDI
Configuration tool is a member of the Toolbox suite of configuration editors, and is available from the
Toolbox window.

1.1.1 Initial Use of the Configuration Tool

RDI component runs on the OpenEnterprise Server

Note, that it is expected that the standard OPCClientRDIDef.sql file will have been included prior to
any configuration being performed using the OPC Client RDI Configuration Tool. This ensures that at
least one entry exists in the OPC Driver table, and the necessary entries are added elsewhere,
allowing the user to begin configuration of the OPC Client RDI.

However, if on start-up the OPC Client RDI Configuration Tool detects that no OPC Driver table
entries are defined, it will present the user with the option to automatically add these essential table
entries.

1.2 The OPC Client RDI Tables

The OPC Client Configuration tool inserts, modifies and deletes entries in a special group of tables that
define the OPC Client
Servers. The tables required for the OPC Client RDI component to function in this way form a
hierarchical relationship, which fulfills both the needs of the OpenEnterprise RDI, and also the OPC
architecture , as the following diagram attempts to illustrate.

RDI's connection with the OpenEnterprise database and the required OPC

For a more detailed explanation of the files used by the OPC Client RDI component, see the OPC
Client RDI help file.

1.3 The Main Interface

The configuration tool interface displays the configuration details as a branching tree. The branches
(or nodes) of the tree reflect the hierarchical relationship of the relevant tables. When the
configuration tool is initially opened, only the root node and OPC Client RDI Driver nodes are
displayed. To begin opening the 'tree' structure if some configuration already exists, click on the plus
sign to the left of the OPC Client RDI Driver node.

At each level, the [Add], [Modify] and [Delete] buttons enable the user to add, modify or delete items
below the selected node. A context menu providing the same functionality is also available.

1.3.1 File Menu

Options on the File Menu enable you to Export your OPC Client RDI configuration from the
OpenEnterprise database as an

SQL Script file, and then Import it back into a freshly built database.

to select a different Export file.

The OPC Client RDI configuration tool will then query the applicable tables and produce the required
script file. A message will inform the user that the Export file has been created.

import might cause on an already configured system, the Import functionality will only be available to

architecture required by OpenEnterprise device drivers.

This option allows you to delete the selected node, the database entry that it represents and any
dependant configuration - e.g. if an OPC Group entry is deleted, then all OPC Items that reference
that Group will be deleted also. A confirmation dialog will require you to confirm the deletion before it
takes place. At this stage it is possible to abort the deletion by selecting the [No] button. If the [Yes]

By default the Import or Export file will be named custom_<Component>.sql, where <Component>
indicates the OpenEnterprise configuration component from which the Import/Export is initiated, and
will be written to the standard OEToolbox export file directory. The Status file has a default name of
custom_<Component>.txt. If a file already exists in the directory with the filename specified, then the
existing file should be renamed such that .old is appended to the end of it, e.g.

When Importing or Exporting, this file will be selected automatically and placed in the File Name field.
The user will however have the ability to override both the name and location if they so require, using
the browse button, or by manually editing the filename.
