Bottom layer communication: M-BUS/485 collector and measurement meter transmit data by M-BUS/485 line with 4 channels, and can connect the meter according to any topological structure. Build in backup battery, could works for 48 hours normally, and the data can be saved for 10 years if power is cut off.
Middle layer communication: Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and collector can be about 3km at wide open area.
Upper layer communication: Communication methods indicate below can be selected between concentrator and management center:
(a) GPRS Communication Mode
(b)Telephone Line Communication Mode
(c) RS232 Communication Mode
(d) Ethernet Communication Mode

The application of INVT-CHV series inverters in the papermaking industry and its steady speed performance prove that the INVT-CHV has a PG vector (closed loop vector) frequency conversion speed regulation scheme that can meet the various requirements in the papermaking process. Requirements such as speed setting, speed fine adjustment, acceleration/deceleration control, speed/torque switching, load sharing, and winding control can all be solved.
INVT-CHV series high-performance vector inverters provide a perfect solution for papermaking machinery, reducing energy consumption, increasing production efficiency and saving users more cost.
The INVT CHV series of high-performance inverters will be used more and more widely in the paper industry.
INVT-CHV inverters from INVT are successfully used in many paper mills in Tianjin. Because the INVT-CHV frequency converter has the characteristics of large starting torque, strong overload capability, fast dynamic response and high speed precision, it can fully meet the requirements of its production process and greatly improve the economic benefits of the enterprise.
