■ Overview<br />

One outstanding feature of modern process control systems is<br />

that they use standardized, modular software functions for the<br />

automation and visualization of process engineering processes.<br />

With the software library "PTE400 V6", you receive a collection of<br />

tried and tested technological function blocks for the rational<br />

and cost-effective generation of SIMATIC <strong>PCS</strong> 7 user software<br />

for process automation and visualization. These blocks have a<br />

high level of standardization, cover a wide range of functions<br />

and meet the requirements of virtually every industry, e.g. chemical,<br />

pharmaceutical, food, beverages and tobacco, oil and gas,<br />

water supply and treatment, and cement.<br />

Block variants with different levels of functionality and faceplates<br />

allowing central modification permit flexible adaptation to<br />

project-specific requirements and special customer needs.<br />

You can benefit from the great potential for rationalization and<br />

the numerous advantages offered by standardization in terms of<br />

validation and in the phases of bidding, engineering, commissioning,<br />

qualification and operation, while retaining all the necessary<br />

flexibility.<br />
