Totally Integrated Automation with SIMATIC PCS 7

The SIMATIC PCS 7 process control system is a significant com- ponent of Totally Integrated Automation (TIA), the unique basis offered by Siemens for uniform and customized automation in all sectors of the production, process and hybrid industries. Using TIA, Siemens is the only company able to offer uniform automa- tion technology on one single platform for all applications of pro- cess automation, starting with input logistics, covering produc- tion or primary processes as well as downstream (secondary) processes, up to output logistics. This is suitable for optimization of all operating sequences of an entire company, i.e. from the ERP (Enterprise Resource Planning) level and MES (Manage- ment Execution System) level to the control level, right down to the field level.

Integrated in a holistic automation solution for a production site, automation of the primary processes is the prime task of SI- MATIC PCS 7. On the other hand, secondary processes (e.g. fill- ing, packaging) or input/output logistics (e.g. raw material distri- bution, storage) are frequently implemented using the PLC- based or PC-based components of SIMATIC.

The advantages of Totally Integrated Automation, in particular the uniform data management, communication and configura- tion, are already evident during planning and engineering, but also during installation and commissioning, everyday operation as well as maintenance, repairs and modernization.

Uniform data management means that all software components access a common database. Within a project, inputs and modi- fications are therefore only necessary at one point. This reduces the work required, and simultaneously avoids potential faults.

Once symbolic identifications have been introduced, they are understood by every software component. Data consistency is also guaranteed even if several persons are working simulta- neously on a project. Parameters defined in the engineering sys- tem can be transferred beyond the network limits down to sen- sors, actuators or drives in the field.

Uniform communication from the corporate management level down to the field level is based on internationally recognized standards such as Industrial Ethernet or PROFIBUS, and also supports the global flow of information via the Internet. Since the hardware and software components involved also use these communications mechanisms, connections are extremely easy to configure, also cross-system or over different networks.

The use of an engineering system with a uniform and matched range of tools minimizes the configuration overhead. The engi- neering tools for the application software, the hardware compo- nents and the communications functions can be called from a central project manager (SIMATIC Manager). This is also the ba- sic application for creation, management, saving and documen- tation of a project.

Compatibility of further developments is guaranteed within TIA. This also guarantees that the company’s investments have a se- cure future, and allows the company to modernize and expand the plants throughout the complete lifecycle.
