Security
information
Siemens provides products and solutions with industrial security functions that
support the secure operation of plants, solutions, machines, equipment and/or
networks. They are important components in a holistic industrial security
concept. With this in mind, Siemens’ products and solutions undergo continuous
development. Siemens recommends strongly that you regularly check for
product updates.
For the secure operation of Siemens products and solutions, it is necessary to
take suitable preventive action (e.g. cell protection concept) and integrate each
component into a holistic, state-of-the-art industrial security concept. Third-party
products that may be in use should also be considered. For more information
about industrial security, visit http://www.siemens.com/industrialsecurity.

Preface
This documentation provides the user with sample applications with which he/she
can access data on SIMATIC BATCH System via function calls to COM API. The
samples show you how to use the COM API Interfaces. The sample applications
mainly focus on the description of the procedure for accessing data, not on creating
and describing the sample applications.
Used technologies
The sample applications are written in Visual Basic 6.0, C++ and C#
programming language.
SIMATIC BATCH COM API uses XML for input and output parameters.
Functional scope
Reading and writing data from/to SIMATIC BATCH System
Notifications on objects: API and SIS events
Controlling batches with archiving
Restriction
Siemens AG 2014 All rights reserved
To limit the scope of this document, it does not include a complete description of:
Programming languages
SIMATIC BATCH COM API
(see main documentation SIMATIC BATCH COM API)
SIMATIC BATCH system
SIMATIC PCS 7
Required knowledge
Basic knowledge of VB 6.0, C++ and C# is required to understand the functional
description.

VB 6.0 sample application
The sample software shows, how to use the COM API interface. You may also use
the sample applications to verify that the COM API interface runs in your
environment.
2.1
The sample source code
The source code is provided only as a supplement to the documentation and
demonstrates the use of the COM API interface. The source contains comments.
Siemens AG 2014 All rights reserved
NOTE
This sample application is not supported by Siemens AG as a fully functional
program. It is provided because we believe it may be useful to you. The sample
application is considered a sample code. We regret that Siemens is unable to
provide support or assistance in the event of specific problems using the sample
application.
The sample code does not have any implemented error handling or a user safety
prompt. Although we have created the sample code carefully, we cannot guarantee
a problem free usage. Therefore, we cannot accept any liabilities. You are free to
use the sample applications and/or modify the source code or use the source code
or parts of it in your programs. There is no licensing fee or restrictions for the usage
of the sample source code.

1. Start: Initialize the COM API interface with the "Init" button. The session handle
will be displayed.
2. Shut down COM API: To close the COM API session, press the "Exit" button.
Then shut down the application with exit button from the menu bar.
3. Browse functions: Use the browse buttons on the left side of the combo
boxes to navigate inside the project. Use the combo boxes to choose or edit
the field. The content of the fields are used as input for other browse functions.

About the source code of the sample
The source code is provided only as a supplement to the documentation and
demonstrates the use of the COM API interface. The source contains comments.

NOTE
This sample application is not supported by Siemens AG as a fully functional
program. It is provided because we believe it may be useful to you. The sample
application is considered a sample code. We regret that Siemens is unable to
provide support or assistance in the event of specific problems using the sample
application.
The sample code does not have any implemented error handling or a user safety
prompt. Although we have tested the sample code carefully, we cannot guarantee
a problem-free usage. Therefore, we cannot accept any liabilities. The sample
code is limited due to error handling and user confirmation dialogs. It is not
possible to claim that this is completely free of side effects. Though the sample
code is carefully tested, we can not guarantee that it will never bring any harm by
proper or improper use in your system. That's why any liability for damage of any
kind is hereby denied. You are free to use the application sample and/or modify the
source code or use the source code or parts of it in your programs. There is no
licensing fee or restrictions for the usage of the sample source code.
3.2
What does the notification sample application do?
The COM API notifies the client application about changes in the SIMATIC BATCH
system. The tool enables you to see the content of the incoming notification.
Notifications can be filtered according to the notification - or object type.
