Globalization and incessantly increasing competitive pressures are forcing companies to continuously increase productivity and shorten product time to market. To this end, it is necessary to continuously optimize engineering procedures and the process, and to simultaneously consider new industrial requirements and directives.

Today, many systems and plants must be expanded and modernized to ensure that companies can continue to provide products meeting market requirements. However, since the installed basis of hardware, application software and know-how of the operating and maintenance engineers represents an enormous value, the safeguarding of investments for companies operating the plants is always assigned a high priority during all modernization plans.

Experience has shown that the success of migration is largely determined by providing a technical solution that optimally matches the customer requirements and the customer’s plant. Minimization of the technical and financial risks together with safeguarding of investments for as long a period as possible are always fundamental aspects. The different lifecycles of the various system components must also be considered, which currently vary from 5 years for PC-based workstations, 15 years for controllers, up to 25 years or more for input/output components and wiring. Therefore Siemens does not consider its task to simply be the complete replacement of an existing system, but in close collaboration together with customers and their system integrators of an individual, future-oriented solution based on the state-of-the-art SIMATIC PCS 7 process control system - always under the directives:

APACS+/QUADLOG 移植组态示例

通过用西门子的 SIMATIC PCS 7 OS 操作和监视系统对基于 APACS+/QUADLOG 控制器的过程控制系统进行移植，用户可以保留已有的成熟功能，同时通过具体升级改造大幅提高功能与性能。当前的操作员和工程系统可配置为现代化的 SIMATIC PCS 7，同时保留 APACS +/ QUADLOG 控制器和嵌套的 I/O 层次。通过这种策略，客户可高效而经济地移植现有系统，无需更换任何控制器、I/O 设备及其布线，也不会有与系统配置相关的任何投资损失。

另外，SIMATIC PCS 7 AS 410 自动化系统在控制器级提供了优异的备选方案，尤其适用于工厂扩展。这些通过工业以太网模块 (IEM) 的控制器 - 控制器通信以及可通过双通道与 APACS + / QUADLOG 控制器和 AS 410 系统通信的 PCS 7 / APACS + 操作员系统支持。

移植至 SIMATIC PCS 7 后，APACS+ 用户还可以受益于全集成自动化（TIA）所提供的大量优点，以及，该系统已经提供的、用来与公司信息网络实现集成的相关功能。这些功能包括与 SIMATIC IT 制造执行系统的接口、基于万维网的监控功能或者与其它 IT 应用的 OPC 数据交换功能。

除了上述技术方面的优势外，良好的未来兼容性也是支持 APACS+/QUADLOG 移植的一个重要依据。这得益于西门子持之以恒地致力于产品研发投资，以及，对 SIMATIC 系列产品提供长期的全球性服务与支持。

采用Zui新的西门子 DBA 技术，可以快速、可靠地实现您的用户程序。据此，可以保护您对当前系统的组态进行的投资。
