ATV 61变频器多泵卡主要任务是使用一台ATV61 变频器来控制整个泵装置，目的：
– 任何流量下系统中均保持恒定的压力
– 通过ATV61 对泵设备进行简单的设置和诊断。
在单靠一台变速泵不能自行满足完整的流量范围的情况下, 系统采用一台变速泵和多台定速泵( 最多4 台)。使用一个PI 调节器进行泵的控制。由压力传感器提供系统反馈。
ngineering, friendly interface and simple maintenance;
2. Industria1 “system communication
Industrial ial “the system uses the international standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and other countries
International standard fieldbus, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa
Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices.
The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber cable and mixed media) and 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.
