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。
network topology can be selected for the system bus
Due to the adoption of tcp/ip protocol, the system can also realize ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.
PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also 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
