优势
Efficient engineering
The seamless integration of SIMATIC Controllers into the common TIA Portal engineering framework permits the integrated storage of data, the smart library concept, and a uniform operating philosophy. This makes the use of universal functions particularly easy.
Variety of diagnostic options
An efficient error analysis and fast error localization with the new uniform display concept – plain text information on the error message in TIA Portal, on the HMI, and in the web server – shortens commissioning times and minimizes production downtimes. SIMATIC S7-1200 offers you a diagnostic functionality that is already integrated in the system, without the need for any further programming.
Innovative design
The SIMATIC S7-1200 Basic Controller can be perfectly adapted to the automation task at hand thanks to its comprehensive expansion options. The modular board concept permits an easy expansion of the controller without changing the physical size. Device replacement is simple, without rewiring through terminal strips.
Safety Integrated
Fail-safe automation is as easy to program as standard automation, and PROFIsafe devices are connected via PROFINET.
Technology Integrated
Simple Motion Control applications, fast counting and measuring tasks, as well as closed-loop control systems (PID) are integrated and can be implemented without additional expansion boards.
Security Integrated
Secured communication, know-how protection, copy protection and access protection prevent manipulation, opening and duplication of blocks by unauthorized persons, and thus protect your algorithm or process.
应用
SIMATIC S7-1200 控制器具有高速计数器、脉宽调制、脉冲序列输出、速度控制和定位等集成技术工艺功能，
适用于温度控制、泵和风机控制以及包括包装机械在内的传送带技术。
