MC协议(MELSEC通信协议)是用于CPU模块或外部设备（个人计算机或显示器等）对MC协议对应设备进行访问的协议。
如果是通过MC协议的控制步骤可进行报文的发送接收的设备，则可以通过MC协议进行通信。
FX5的串行口的情况下，可以使用MC协议的QnA兼容3C/4C帧进行通信。
能够通过个人计算机、显示器等，使用MC协议读取、写入CPU模块的软元件。
通过读取、写入软元件，能够利用个人计算机、显示器等对CPU模块实施动作监视、数据分析、生产管理等。
supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus interface cards (card types can be different),
Each card is connected to a fieldbus 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 in and out with power.
The field controller PS has the following features:
o
Flexible: it supports all international standard open fieldbus and can be mixed
4 high-speed fieldbuses can be connected at the same time (max. 12 MBD)
Simple project: only use the same tool CBF (control build f) software for configuration, debugging and diagnosis
