已经开发出用于工业环境且符合 EMC 法定要求的 SIMATIC 产品及其组件。 但是，在安装控制器之前仍然需要进行 EMC 评估，以便确定可能存在的干扰源并在安装时考虑这些因素。
电磁兼容性 (EMC) 描述了电气设备在特定电磁环境中正常运行的能力。 不允许以不可接受的方式影响环境自身或电气设备。
电磁干扰可能以各种方式影响自动化系统。 最重要的干扰及其产生的原因如下：
● 电磁场对于系统产生直接的影响
● 由总线信号（例如，PROFINET）引起的干扰耦合
● 通过过程接线影响系统的干扰
● 通过电源和/或保护性接地到达系统的干扰 2010年4月西门子全球技术资源库发布了用于S7-1200 CPU的集成PN接口通过Modbus/TCP与PAC3200(CE-X22)进行数据交换的功能块库，本文主要介绍了ModbusTCP的通讯原理，并详细描述以Modbus slave软件为例模拟第三方设备如何使用该功能块库与S7-1200的集成PN接口进行Modus TCP通讯，希望通过本文档，能够给读者S7-1200CPU集成PN口的Modbus TCP通讯入门指导
Advanced process control systems for all process control applications. SIMATIC PCS7 V7.0 Product Overview (Chinese)
SIMATIC PCS7 V7.0 can not only automatically complete the production process from material input to product output in a unified and integrated way, but also integrate the existing electrical infrastructure into the process control system. This means that an integrated automation solution for the entire production site is also available with SIMATIC PCS 7 V7.0.
SIMATIC PCS 7 is seamlessly Integrated into TIA (Totally Integrated Automation) and includes a full range of collaborative products, systems and solutions to achieve a unified and customizable automation system for all production, process and cross areas. SIMATIC PCS 7 can be integrated into an enterprise’s hierarchical communication network through standardized interfaces based on international industry standards and internal system interfaces for direct data exchange. In this way, the process data needed to evaluate, plan, coordinate, and optimize running processes, production, and business processes can be accessed anywhere, anytime within the enterprise.
SIMATIC PCS 7 system supports SIMATIC IT connected to Siemens Manufacturing execution system. SIMATIC IT can detect the data of ERP layer and control layer in real time, establish the model of all production knowledge, and accurately define the operation process. SIMATIC PCS7 V7.0 Process Control System Introduction Guide – Beginners on the Road (Chinese)
Explain the fundamentals of SIMATIC PCS 7 software components and how they interact in the context of engineering and process patterns using easy-to-understand example projects.
SIMATIC PCS7 Process Control System Introduction Guide – Part 1 (Chinese)
A preliminary overview of the process control system enables you to create simple projects on your own. The project can be configured on an existing SIMATIC PC station.
The PCS 7 project includes the following objects:
? The hardware configuration
? block
? CFC chart and SFC chart
These objects will always be included, regardless of how many operator stations, modules, and networks there are. SIMATIC Process Control System PCS7 Time synchronization function manual (Chinese)
