对Modbus适配器模块NMBA-01的安装与启动指南进行了介绍。
Modbus是一种异步串行协议。Modbus协议不规定物理接口，典型的物理接口是RS-232和RS-485。NMBA-01使用RS-485接口。
NMBA-01 Modbus适配器模块是ABB传动装置的一个可选件，它实现了传动装置和Modbus系统之间的连接。在Modbus网络中，传动装置被认为是从机。通过NMBA-01 Modbus适配器模块，我们可以：
·向传动装置发送控制命令（起动，停止，允许运行等）。
·向传动装置发送速度或力矩给定信号。
·向传动装置中的PID调节器发送给定信号和实际值信号。
·从传动装置中读取状态信息和实际值。
·改变传动参数。
·对传动装置进行故障复位。
·进行多传动控制。

lder without additional software. The interface card can be configured redundantly (separated between each other

Redundant basic unit pm802f) and can be plugged in and out and replaced online.

Fi830f: PROFIBUS DP interface card, as the master station, can connect 126 PROFIBUS DP slave stations, and the communication rate can reach 12mbd

One PS can plug in 4 fieldbus interfaces, connect 496 fieldbus devices, and one city (subsystem) of industrial “system can

Connect 4960 fieldbus devices (10000 i/0).

Fi820f: two serial interfaces are provided to connect the serial protocol equipment. The maximum transmission rate is 38.4kbd and can be configured. Its Standards Association

Modbus Different physical interfaces can be selected for different connection schemes, RS422, RS485, RS232. All interfaces are electrical isolation

Away. And the redundant operation is realized by two redundant field controllers.

Fi8i0f card is a triple can bus protocol interface card (rate 1mbd) used to connect industrial ial “conventional process control station

The i/0 protection unit of the PS is used to receive process signals from the rack mounted i/0 modules supported by the PS. Each field controller PS can only be configured

-Block fi810f card. — The two fi810f interface cards on the redundant PS. can be switched redundantly.

 

S800 and S900 are distributed i/0 for process control stations. They communicate with their controllers through Prof ibusdp Fieldbus

Communication, which can be installed in the controland PA three levels, DP communication rate can be as high as 12Mb. The CAN (DIN/IS011898 standard) bus
The biggest feature is its super sturdiness and data security. The system of course also supports Modbus. The communication with the intelligent field instrument is through
IART protocol or field bus (31. 25Kb ProfibusPA and FF bus).
The system communication between the operation management level and the process control level is realized by Di giNetS network (Industrial Ethernet/IEEE802.3 standard),
Users can choose the communication transmission medium (ordinary cable or optical fiber) and network topology according to the actual situation of the application.
