Introduction 1.1 Product Overview RS-FS-N01 wind speed transmitter, compact and lightweight, easy to carry and assemble, design cups can be efficiently obtain information about the wind speed, high-quality aluminum alloy housing, external spray plating process, has good anti-corrosion, anti- Erosion and other characteristics, to ensure long-term use of the transmitter without rust phenomenon, at the same time with the internal smooth bearing system to ensure the accuracy of information collection. Is widely used in greenhouse, environmental protection, weather stations, ships, docks, breeding and other environmental wind speed measurement. 1.2 Features Range: 0- 30m / s, the resolution of 0.1m / s Anti - electromagnetic interference treatment Using the bottom of the outlet way, completely Du air plug rubber pad aging problem, long-term use is still waterproof The use of high-performance imported bearings, rotating resistance is small, accurate measurement Aluminum case, mechanical strength, high hardness, corrosion resistance, long-term use in outdoor rust Equipment structure and weight have been carefully designed and distributed, the inertia is small, responsive ModBus-RTU standard communication protocol, easy access, 1.3 Main Specifications 10 ~ 30V DC DC power supply (default) Transmitter circuit operating -20 ℃ ~ + 60 ℃, 0 % RH ~ 80% RH temperature 485 (modbus) protocol Baud Rate: 2400, 4800 (default), 9600 Data bit length: 8 Communication Interface Parity mode: none Stop bit length: 1 Shandong RenKe Control Technology Co.,Ltd. 4 www.temperaturehumiditysensor.com Manual wind speed transmitter (485 type) The default ModBus Address: 1 Support Function code: 03 Be configured with software provided by the parameter settings configuration 485 Resolution 0 .1 m / s Measuring range 0 ~ 30m / s Dynamic Response Time ≤ 0.5s Start the wind speed ≤ 0.2m / s 2. Installation instructions 2.1 Equipment installation check Equipment List: ■ transmitter equipment 1 ■ four mounting screws ■ certificate, warranty card, service card, etc. ■ 12V / 2A 1 water supply station (optional) ■ USB to 485 (optional) ■ 485 terminating resistor (optional) 2.2 Interface Description Wide voltage power input 10 ~ 30 V can. Note that the signal line 485 when the terminal A \ B two lines can not be reversed, the address bus between multiple devices must not conflict. 2.3 Electrical wiring Line color Description Electricity brown A positive power supply (10 ~ 30 V DC) source black Negative power supply through yellow 485 -A letter blue 485 -B Shandong RenKe Control Technology Co.,Ltd. 5 www.temperaturehumiditysensor.com Manual wind speed transmitter (485 type) 2.4 Description field wiring When a plurality of types of devices 485 connected to the same bus, the field wiring have certain requirements, refer to the specific data packet "485 field wiring device manual." 2.5 Installation Using mounting flange, threaded flange connector tube so that the lower portion of the wind speed sensor is firmly fixed on the flange, the chassis Ø65mm, open Ø6mm four mounting holes are circumferentially Ø47.1mmusing only bolts to securely in the bracket On the whole set of instruments, to maintain the best level, to ensure the accuracy of wind speed data, flange connection easy to use, able to withstand greater pressure. 2.6 Considerations 1. Never disassemble, but can not touch the sensor core, so as to avoid damage to the product. 2. The device as far away from the interference power, in order to avoid inaccuracies in the measurement, such as inverter, motor, installation, disassembly must disconnect the power transmitter into the water cut-off can lead to irreversible changes in the transmitter. 3. Prevention of chemicals, oil, dust and other directly against the sensor, not the condensation, long-term use in extreme temperatures to prevent thermal shock. 3. Configure the software installation and use 3.1 Software Selection Open the data package, select "Debug Software" --- "485 parameter configuration software" to find Open it. 3.2 parameter settings ①, select the correct COM port ( "My Computer - Properties - Device Manager - Port" inside view COM port), a figure below lists several different names drive 485 converter. Shandong RenKe Control Technology Co.,Ltd. 6 www.temperaturehumiditysensor.com Manual wind speed transmitter (485 type) ②, just take a single piece of equipment and power-up, click on the software testing baud rate, the software will test the current baud rate and device address, the default baud rate is 4800bit / s, the default address is0x01. ③, the address needs to be modified according to the use and the baud rate, and can query the current state devices. ④, if the test is unsuccessful, recheck the wiring and equipment 485 driver installation. 4. Communication Protocol Shandong RenKe Control Technology Co.,Ltd. 7 www.temperaturehumiditysensor.com Manual wind speed transmitter (485 type) 4.1 The basic parameters of Communications Ed code 8-bit binary Data bits 8 Parity bit no Stop bit 1 Error CRC (cyclic redundancy code) checking 2400bit / s, 4800bit / s, 9600 bit / s can be set, the default setting Baud rate is 48 00bit / s 4.2 Frame format definition data Using M odbus - RTU communication protocol, in the following format: Initial structure ≥ 4 byte time address code = 1 byte function code = 1 byte Data area = N bytes Error checking = 16-bit CRC End structure ≥ 4 byte time Address code: for the address of the transmitter, the communication network is the only (factory default 0x01). Function Code: The host command functions such directions, the transmitter has used only the function code 0x03 (read data register). Data area: data area is the specific communication data, note data of 16bits endian! CRC code: two-byte checksum. Host query frame structure: address code 1 byte function Register start code address 1 byte Register Check length 2 bytes code low 2 bytes Check code high 1 byte 1 byte Slave Answer Frame Structure: address code function code Valid bytes Shandong RenKe Control Technology Co.,Ltd.

Common Problems and Solutions 5.1 device can not connect to a PLC or PC possible reason: 1) computer has multiple COM ports, port selection is not correct. 2) device address error, or there is a duplicate device address (factory default all 1). 3) The baud rate, parity, data bits, stop bits error. 4) The master polling interval and response wait time is too short, it is required more than 200ms provided. Shandong RenKe Control Technology Co.,Ltd. 9 www.temperaturehumiditysensor.com Manual wind speed transmitter (485 type) 5) 485 has turned off, or A, B line reversed. 6) the number of devices or the wiring too long, to be near the power supply, plus booster 485, while increasing 120 Ω termination resistor. 7) USB drive switch 485 is not installed or damaged. 8) equipment damage. 6.
