GE Fanuc 90-30系列PLC Modbus RTU 主站通讯用户手册（中文）说明了Modbus® RTU 主站的操作。
Modbus 串行通讯协议是一项开放标准，用于PLC之间以及相关设备间的数据通讯串行通讯,串行通讯协议是一种开放的 数据通讯标准 。 Modbus 串行通讯标准提供两种传输模式，一种是使用专用的可打印字符 (Modbus ASCII), 另一种是使用二进制数 (Modbus RTU)。
90™-30 系列中的IC693CPU363 以及 VersaMax® 的CPU 模块 IC200CPU001, IC200CPU002, IC200CPU005 和IC200CPUE05目前均支持Modbus RTU 主站通讯。

Braking performance. The system can connect not only conventional i/0, but also PROFIBUS, FF, can, MODBUS and other field bus devices. System tool
It has high flexibility and excellent scalability, whether it is the control of small-scale production devices or the large-scale integrated control of the whole plant, even
The industrial “system can cope with the field equipment maintenance management and cross plant production management control applications
As an important member of industrial “family, AC800F system fully embodies industrial” initiated and led by ABB in technology
Information technology) a new trend.
The system is divided into two levels: operation management level and process control level. At the operation management level, not only the traditional control system monitoring operation function is realized
Can (operate and display, print, trend display and alarm), and also complete system hardware diagnosis and data exchange between different systems
Yes. The process control level realizes various loop adjustments including complex control (various PID, ratio, Simith, etc.) and high-speed logic control
Control, sequence control and batch intermittent control functions.
The internal communication of the process control station (between the controller and various intelligent devices such as i/0 or field instruments) adopts the international standard field general
Line. The field controller supports various field buses such as PROFIBUS, which is the most widely used open field bus in the world
Line international standard, divided into FMS, DP and PA, DP communication rate can be as high as 12MB. Can (din/is011898 standard) bus
The biggest feature is its super robustness and data security. The system also supports MODBUS. The communication with intelligent field instruments is through
IART protocol or fieldbus (31.25kb profibuspa and FF Bus).
The system communication between the operation management level and the process control level is realized by the di ginets network (Industrial Ethernet /iee802.3 standard),
The user can select the communication transmission medium (ordinary cable or optical fiber) and network topology structure according to the actual situation of the application.
