The second generation of our company SM5100 ZigBee DTU is a simplified version of the RTU, it may be using ZigBee communication digital sensor data into standard ModBus RTU data or a standard ModBus TCP data (can be customized) in specified registers for use by PC, which deals with two aspects of communication:
1. downstream data: with sensor communication using standard modernization project of shengli communication protocol or oil A11 items using standard communication protocols (can be customized);
2. uplink data: station control center or other control devices such as PLC communications using standard standard Modbus RTU or ModBus TCP (customizable) protocol or the passthrough mode (test).
Uplink data communication protocol standard Modbus RTU or ModBus TCP standards (customizable)-based (communications data link layer), refer to the GB z-19582.1-2004 specification for industrial automation network based on Modbus Protocol;
The products matching the criteria of digital sensors can be widely used in the Internet industry, including industrial automation, environmental protection, agriculture, forestry, water, coal, petrochemical, and other fields.
