SIMATIC HMI设备TP177A、TP177B、OP177B（WinCC flexible）操作说明（中文）
177 系列面板是对已广为人知的 170 HMI 设备进一步发展而来。 全新的 TP 177A、TP 177B 和 OP 177B 面板有助于提高基于文本或图形的项目的使用效率，适用于机器和工厂中从简单到中等级别的 HMI 操作和监视任务。 如以往一样，可以组态使用亚洲字符集和西里尔字母字符集的项目。 TP 177A 可垂直安装的能力以及 TP 177B 的非易失性报警缓冲区，使得开辟新应用领域成为可能。 另外，TP 177B 和 OP 177B（取决于型号）还提供了连接 PROFIBUS 和 PROFINET 的接口。
TP 177B 4″ 提供了 4.3″ TFT 宽屏格式显示屏。与相似的 4:3 格式显示屏相比，该显示屏将 HMI 设备的可视区域扩展了大约 25 %。HMI 设备也提供了四个具有触觉反馈的功能键。与直观的触摸操作组合使用，设备可实现最高的操作效率。除了 MMC 卡外，TP 177B 4″ 还支持 SD 卡和 USB 记忆棒。
OP 177B 还提供了一项附加功能。 现在，除了覆膜键盘外，还可使用广泛应用的触摸屏来操作 OP 177B。 功能键可组态成特定画面的系统按键。
TP 177A、TP 177B 和 OP 177B 面板具有调试时间短、用户存储器容量大以及高性能等特征，并且这些面板为基于 WinCC flexible 的项目进行了优化。

fieldbus international standard in the world, divided into FMS, DP and PA
Level 3, DP communication rate can be as high as 12Mb. Profibus is used to connect intelligent devices such as distributed I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.

The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface
1EC870-5 protocol communication interface (Telecontrol)
4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible: supports all international standard open fieldbuses and can be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
