RION/solar tracking tilt angle sensor inclinometer sensor solar tracker angle tracking sensr/MCA416M - 1

1) MODBUS protocol stipulates that it should be over 3.5 byte time between two data frame(Eg. Under 9600 baud rate, the time is 3.5* (1/9600) *11 =0.004s ). This sensor increase the time to 10ms for a enough margin, so please set 10ms time interval at least between each data frame. Host send command--10 ms interval--slave response command--10ms time interval-host send command... 2) MODBUS protocol stipulates broadcast address-content relate to 0. This sensor also capable of receiving broadcast address content but without response. So broadcast address 0 could be used as(below is reference only): 1. Set all the addresses of inclinometers mounted on BUS with this Model NO as one address. 2. Set all the inclinometers mounted on BUS with this Model NO to be relative/absolute zero. 3. Test all inclinometers mounted on BUS. Host inquires angle command by sending 3) 0 address to BUS, if the communication light flashes, then communication is in proper function. 4) for sake of system reliability, when set address and relative/absolutive command, it should be send two times continuously, which means two successful sending with continuous responses by slave, that is no data frame between the two inquiries, or the command will be locked till power off. Set as below: Send set address command--stand by for slave response set success command--send again set address command(no other command between)--stand by for slave response set success command--successful revision After power-up, two set commands mentioned above could be only set once, if need reset, please set after power on again. 5) the communication light will flash once when proper communications accumulate to a ceratin times. 1. Data frames format: RTU Mode. Communication Parameter:Baud rate 9600 bps. Data frames:1 Start bit,8 datas,even parity check,1 stop bit. 2. Read angle data: Modbus FUNC 03H. Host Computer Inquiry Command Read the measured data command applicaton example Host computer sending ^ Slave computer response Slave Computer Response Inclinometer Address FUNC Data Length Data word 1 upper 8 bits Data word 1 lower 8 bits Data word 2 upper 8 bits Data word 2 lower 8 bits Data word 3 upper 8 bits Data word 3 lower 8 bits Data word 4 upper 8 bits Data word 4 lower 8 bits CRC Note:Slave computer response data domain of the frames is50H , 46H , 00H , 00H , 23H , 20H , 00H , 00H The X axis is the 1 -4th byte of the data field, the Y axis is the 5th-8th byte of the data field, and the low byte is first. The representation of the angle is the point number representation. One point corresponds to 0.01°, and 0.01 *(point-offset) is the angle. If the measurement range is + -90°, the total number of points is 18000 points, so 0 corresponds to -90°, 18000 corresponds. + 90°, 9000 corresponds to 0.Take the above data frame as an example: the angle conversion process is as follows:1) Get the current angle points, the low byte is first, the X axis is 4650H, and the Y axis is 2023H.2) Convert to decimal, X axis: 4650H ^ 180000, Y axis: 2023H ^ 8227.3) Subtract the offset 9000 (note: this value is an amount related to the measurement range), X-axis: 18000-9000 = 9000, Y-axis: 8227-9000 = -773.4) Get the final angle, X axis: 9000 * 0.01 = 90.00°, Y axis: -773 * 0.01 = -7.73° Read the measured data command applicaton example Host computer sending ^ Slave computer response Assuming that the sensor of this example has a measurement range of + -45 degrees, the total number of points is 9000 points.Therefore, 0 corresponds to -45°, 9000 corresponds to +45°, and 4500 corresponds to 0°. The angle conversion process is as follows: 1) Get the current angle points, the low byte is first, the X axis is 0000H, and the Y axis is 2300H.2) Convert to decimal, X axis: 0000H ^ 0, Y axis: 2300H ^ 8960.3) Subtract the offset 4500 (note: this value is an amount related to the measurement range), X-axis: 0-4500 = -4500, Y-axis: 8960-4500 = 4460.4) Get the final angle, X-axis: -450 * 0.01 = -45.00°, Y-axis: 4460 * 0.01 = 44.60°. 3.Setting inclinometer relative/absolute ZERO: Modbus FUNC 06H Setting relative/absolute ZERO command Note: 0010 is register address, the register control inclinometer output is relative ZERO or absolute ZERO. If nonzero (As example as above, was written in 00FFH) , the output is relative ZERO. On contrary if zero (will change the fiveth and sixth bytes to 00H), then is absolute ZERO,. the last two bytes is CRC checksum . 4. Setting inclinometer address: Setting inclinometer addresss code command CHINA RION TECHNOLOGY INCLINOMETER | TILT SWITCH | DIGITAL INCLINOMETER | ELECTRONIC COMPASS ACCELEROMETER | GYROSCOPETHE SYSTEM | INERTIAL MEASUREMENT UNIT ATTITUDE AZIMUTH COMBINATION SYSTEM | GYRO SYSTEM | GPS POSITIONING SYSTEM [ V1.0 ) Note: 0011H is register address, the register control inclinometer address.Above example, the inclinometer address is changed to 0004H, the last two bytes is CRC checksum.
