Siemens S7-1200 2015版样本

通信11 S7-1200 可实现 CPU 与编程设备、HMI 和其它 CPU 之间的多种通信。

警告PROFINETPROFINET 用于使用用户程序通过以太网与其它通信伙伴交换数据：●在 S7-1200 中，PROFINET 支持 16 个最多具有 256 个子模块的 IO设备，PROFIBUS 允许使用 3 个独立的 PROFIBUS DP 主站，每个 DP 主站支持 32个从站，每个 DP 主站最多具有 512 个模块。

●S7 通信●用户数据报协议 (UDP)●ISO on TCP (RFC 1006)●传输控制协议 (TCP)通信PROFINET IO 控制器作为采用 PROFINET IO 的 IO 控制器，CPU 可与本地 PN 网络上或通过 PN/PN耦合器（连接器）连接的最多 PROFIBUS和PROFIBUSPROFIBUS 用于使用用户程序通过 PROFIBUS 网络与其它通信伙伴交换数据：●借助 CM 1242-5，CPU 作为 PROFIBUS DP 从站运行。

●借助 CM 1243-5，CPU 作为 1 类 PROFIBUS DP 主站运行。

●PROFIBUS DP 从站、PROFIBUS DP 主站和 AS-i（左侧 3 个通信模块）以及PROFINET 均采用单独的通信网络，不会相互制约。

AS-i通过 S7-1200 CM 1243-2 AS-i 主站可将 AS-i 网络连接到 S7-1200 CPU。

CPU 至 CPU S7 通信您可以创建与伙伴站的通信连接并使用 GET 和 PUT 指令与 S7 CPU 进行通信。

TeleService 通信在通过 GPRS 的 TeleService 中，安装了 STEP 7 的工程师站通过 GSM 网络 Internet和与具有 CP 1242-7 的 SIMATIC S7-1200 站进行通信。

该连接通过用作中介并连接到Internet 的远程控制服务器运行。
