Automation Wrapper and Compatibility. I would like to use an Automation Wrapper. Is there a unique Automation Wrapper compatible with all specifications? I would appreciate somo help.. Thanks in advance. The automation wrapper is for VB6. There is no real market need for 1. If you really want support you will need to buy a commercial toolkit.

Sorry I have not fully understood You mean than I have to use the. Randy Thank you very much for your help and sorry that I am a bit confused.

In addition, spelling, grammer, formatting and minor clarifications were added to improve the quality of the specification. Revision 2. Also correct an error in the property definitions in Appendix D were off by 1.

LocaleID for SetState to make it clear the behaviour is optional. This now clearly implies that the method outputs specifically the ppErrors returns are defined in this case. Other adjustments to the text were to make error returns more consistant across functions.

Clarify GetItemID behavior. Specifically: 0 is an allowed value. Also add section 4. Although changes were made throughout the document, the following areas are or particular importance: This is now refered to as the OPC Data Access Specification as there are other OPC efforts underway. The Automation Interface specification has been separated into a separate document. All previous 1.

Async and exception based connections should now be done using ConnectionPoints rather than. A new convenience interface is defined.

A ShutdownRequest capability is added via a Connection point on the Server object and a Client side IOPCShutdown interface that allows the server to request that all clients disconnect from the server. This interface will also be used by other OPC server types.

This interface provides several common LocaleID related functions. Synchronous Interfaces Therefore, the developer of the respective component is expected to be fluent in the technology required for the specific component. OPC Data Access 3. Different vendors may provide OPC Servers. Vendor supplied code determines the devices and data to which each server has access, the data names, and the details about how the server physically accesses that data. Specifics on naming conventions are supplied in a subsequent section.

At a high level, an OPC server is comprised of several objects: the server, the group, and the item. The OPC group object maintains information about itself and provides the mechanism for containing and logically organizing OPC items.

The OPC Groups provide a way for clients to organize data. For example, the group might represent items in a particular operator display or report. Data can be read and written. Exception based connections can also be created between the client and the items in the group and can be enabled and disabled as needed. The OPC Items represent connections to data sources within the server.

Therefore, there is no external interface defined for an OPC Item. Associated with each item is a Value, Quality and Time Stamp. Note that the items are not the data sources – they are just connections to them.

The OPC Item should be thought of as simply specifying the address of the data, not as the actual physical source of the data that the address references. The architecture and design makes it possible to construct an OPC Server which allows a client application to access data from many OPC Servers provided by many different OPC vendors running on different nodes via a single object. A revised automation interface may be provided with release 3.

This is shown below. The OPC Specification specifies COM interfaces what the interfaces are , not the implementation not the how of the implementation of those interfaces. It specifies the behavior that the interfaces are expected to provide to the client applications that use them. Included are descriptions of architectures and interfaces that seemed most appropriate for those architectures.

There are several unique considerations in implementing an OPC Server. The main issue is the frequency of data transfer over non-sharable communications paths to physical devices.

Thus, we expect that the OPC Server will either be a local or remote EXE which includes code that is responsible for efficient data collection from a physical device.

OPC servers must implement the custom interface, and optionally may implement the automation interface if defined. It is also expected that the server will consolidate and optimize data accesses requested by the various clients to promote efficient communications with the physical device.

For inputs Reads , data returned by the device is buffered for asynchronous distribution or synchronous collection by various OPC clients. The primary intent of OPC Data Access is to provide the interfaces for data acquisition accessing services in support of the vertical architecture serve data from a device to a client application on a higher level computer. Companion interfaces are being added to provide needed functionality to extend the accessing of data.

This includes the ability to share server data between devices on different industrial networks. OPC Common Definitions and Interfaces contains common rules and design criteria and the specification of interfaces which are common for several topics including Data Access.

It provides the mechanism for communicating the structure of the data as well as the actual values of the data. The types of sources available are a function of the server implementation. These groups allow clients to organize the data they want to access. A group can be activated and deactivated as a unit. A group also provides a way for the client to subscribe to the list of items so that it can be notified when they change.

The client sees only the interfaces. Thus, the objects described here are logical representations which may not have anything to do with the actual internal implementation of the server. The following figure is a summary of the OPC Objects and their interfaces. Note that some of the interfaces are Optional as indicated by [ ]. Only the server specific information is persistently stored. All client configuration information Group and Item Definitions must be persistently stored by the respective client application.

All Handles that are defined in the system are not guaranteed to have the same value between sessions of the client and server conversation. It is important to distinguish the address space of the server also known as the server configuration from the small subsets of this space that a particular client may be interested in at a particular time also known as the groups and items.

The details of how these client specific groups are maintained are discussed in detail in this specification. The persistent storage of groups is the responsibility of the respective clients. The details of how the server address space is defined and configured are intentionally left unspecified. For example the server address space might be:. Entirely fixed e. Configured entirely outside of the OPC environment e.

Automatically configured at startup by an intelligent server which can poll the existing system for installed hardware or interfaces. Automatically configured on the fly by an intelligent server based on the names of the data items the client applications are currently requesting.

It is expected that this server address space is stable and is managed within the server. The clients will define and manage the relatively small lists of items called groups as needed from time to time. The clients direct the server to create, manage and delete these groups on their behalf persistence of the groups is the responsibility of the client application.

Such groups can contain requests for data from only one particular OPC Server object. In order to access data, a client application will need to specify the following:. The vendor specific OPC Item Definition the name of the specific data item in the servers address space. It is beyond the scope of this specification to discuss the implications of this on the architecture and user interface of the client program. For example, most applications want to insure that the value, quality and time stamp attributes of a particular item are in sync.

Also, a reporting package might want to insure that a group of several values read together as part of a Batch Report are in fact part of the same batch. Finally, a recipe download package would want to insure that all of the values in the group were sent together and that the recipe was not started until all of the values had been received.

These are just a few examples where synchronization is important. The short answer is that OPC itself cannot insure that all of these synchronization tasks can be accomplished. Additional handshaking and flag passing between the client application and the device server to signal such states as ready and complete will be required. There are also things that need to be specified about the behavior of OPC servers to assure that OPC does not prevent this sort of synchronization from being done.

It will be seen later that OPC allows explicit reads and writes of groups of items or of individual items as well as exception based data connections OnDataChange. Without jumping ahead too far it is possible to make some general observations about these issues and about server behavior. In general, OPC Servers should try to preserve synchronization of data items and attributes that are read or written in a single operation.

Synchronization of items read or written individually in separate operations is not required. Use OPC Recipe. No limit on the number of items as data source and target.

The driver rebuilds the connection if the device level group fails to add, similar to a shutdown notification, status, or watchdog failure.

Fixed an issue where consecutive writes of the same value could result in bad tag quality. Resolved an issue where removing invalid items could result in a hang of the runtime. Asynchronous Read and Write methods are the default and remain the optimal choice for most applications.

Resolved an issue that could cause tag reads using ReadMaxAge to always read from cache. Login name. Automation Wrapper and Compatibility. I would like to use an Automation Wrapper. Is there a unique Automation Wrapper compatible with all specifications?

Previously we would keep attempting to read the tags, expecting an initial update. In the case that the tag is invalid, we won\’t receive an update, and should report the tag is Bad: Out of Service. Improved performance of ATG. The driver now removes all items from the underlying server when the DA Client\’s device is configured as disabled. Fixed issue where the driver returned an invalid read value when an item did not receive an update from the DA Server. We now continue to process the read request until we have a valid return value.
