SIMATIC DP，CPU 1516PRO-2 PN 用于 ET 200pro， 中央处理器，带 主存储器 1MByte 用于 程序及 5MByte 用于数据， 第 1 个接口：PROFINET IRT 带 3 端口交换机， 第 2 接口：PROFINET RT， 10 ns Bit 高性能， 防护等级：IP65/67， 需要 SIMATIC 存储卡， 需要连接模块 SIMATIC ET 200pro is a very rugged and powerful 模块型 distributed I/O system with IP65/67 degree of protection, for installation outside the control cabinet directly at the machine. The modules can either be plugged directly into an ET 200pro CPU or connected to a central controller via PROFINET or PROFIBUS. It is also possible to connect to the central controller wirelessly via WLAN, which allows the use of the SIMATIC ET 200pro for electric monorail systems, automated guided vehicles, in building management, and in warehouse logistics. Due to its comprehensive range of modules, it is especially useful where a fine-模块型 configuration with different functions is required in harsh ambient conditions. The separation of module and bus/power connection technology allows a module to be swapped during operation (so-called "hot swapping"), which ensures the availability and productivity of the machine in connection with the detailed diagnostics. The system provides a very wide range of modules. In addition to various digital and analog input and output modules with a wide range of characteristics, a number of fail-safe modules for applications up to SIL 3 / PLe are also available. The ET 200pro system provides integrated solutions especially for motor control in the form of motor starters and frequency converters, which are also available as fail-safe variants. An IO-Link master and a module for connecting RFID component devices via the RS 232 / 422 interface round out the portfolio.
