■ 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 />
