FDNA-01 DeviceNet 适配器模块是用来将ABB传动接入DeviceNet网络的可选设备。在DeviceNet 网络中，传动单元是一个从站点。通过FDNA-01 DeviceNet 适配器模块可以实现下列功能：
• 向传动单元发出控制命令( 起动、停止、运行允许等)
• 向传动单元发送电机转速或转矩给定值
• 给出传动的一个过程实际值或PID 控制器的过程给定值
• 从传动单元读取状态信息和实际值
• 修改传动参数值
• 对传动故障进行复位
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 appli
cations 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
