2Changes since Version 3

2.1Interface cancelations

The interfaces listed in the following section were changed in Version 4.0 of GINA. This ver- sion contains the new variant. Each section indicates the GINA version as of which the rel- evant interface or its old variant is no longer supported.

G_Exception eliminated

In earlier versions, GINA used the exception handling simulation of the Generic++ class library [11] on some platforms. To facilitate this, the GINA exception classes were derived internally from the Generic class G_Exception. This derivation process has had to be eliminated because of a compiler problem.

The message and name methods derived from G_Exception described in the Reference Manual are omitted from GINA Version 4.0 and later.

OQL

Version 3.0 of GINA sees the introduction of a new, improved interface for database queries which is a subset of ODMG-OQL. Up to this version, the new OQL existed in parallel to the old one and the user can decide the variant to be used.

Access via the old OQL will be eliminated as of GINA Version 4.0.

Entering special options in the mgen2 and mdiff generators

As of Version 3.3, special options (e.g. noansi, nohinfo) for the mgen2 and mdiff gen- erators can be defined in a file, i.e. you no longer need to specify them individually in the call. Instead, you reference an existing file using the -koption when you call a generator. All of the special options can be specified in this file.

As of Version 3.3, special options were supported both as call options and via a special op- tion file. As of Version 4, however, special options will only be read from a file.

Siemens V 4.0 also emphasizes the importance of automation and robotics. By integrating robotic process automation (RPA) into manufacturing workflows, companies can achieve higher levels of efficiency while reducing human error. This automation not only speeds up production times but also allows workers to focus on more complex tasks that require human ingenuity.

Additionally, Siemens V 4.0 supports advanced simulation and digital twin technology. Through the creation of virtual models of physical assets, manufacturers can simulate different scenarios, identify risks, and optimize design processes before implementation. This capability accelerates innovation while minimizing waste and resource consumption.

Another important characteristic of Siemens V 4.0 is its scalability. The platform can be tailored to meet the unique needs of various industries, from automotive to pharmaceuticals. This flexibility ensures that companies of all sizes can leverage its capabilities, driving global competitiveness.

In conclusion, Siemens V 4.0 is revolutionizing the manufacturing landscape through its comprehensive suite of features, including IoT connectivity, AI-driven insights, automation, and digital twin technology. By adopting this platform, businesses can transition toward more efficient and sustainable operations, ultimately preparing them for the future of industrial production.
