Page 18: Modbus Rtu Protocol
MODBUS RTU PROTOCOL 3.1 INTRODUCTION TO MODBUS Model 6180 inclinometers use the industry standard Modbus Remote Terminal Unit (RTU) protocol to communicate with the chosen readout method. As the name suggests, Modbus was designed to work on what is known as a bus network, meaning that every device receives every message that passes across the network. -

Page 21: Data Reduction
DATA REDUCTION 4.1 INCLINATION CALCULATION The output of the 6180 Inclinometer Sensor is a corrected angle of inclination. The standard sensor has a full range of ±90° and a calibrated range of ±15°. Register values for the Gauge Factor and Offset are factory-written to the Modbus registers for each sensor using calibration data. -
Page 22: Troubleshooting
TROUBLESHOOTING Maintenance and troubleshooting of Model 6180 In-Place Inclinometers is confined to periodic checks of the cable connections. The sensors are sealed and there are no user serviceable parts. Should difficulties arise, consult the list of possible solutions shown below. Refer to Appendix C for Modbus error codes. -

APPENDIX D. CRBASIC PROGRAMMING D.1 SAMPLE CR1000 PROGRAM The following sample program reads one 6180 sensor string with three biaxial sensors. The string in this example communicates with the CR1000 through the control ports C1 and C2, which are setup as COM1. A RS-485 to TTL converter required. - Page 30 'Use Modbus command to retrieve A Axis and B Axis Degree Readings ModbusMaster (ErrorCode,ComC1,115200,Count,3,A_Axis_Degrees(Count),&H101,1,1,10,0) ModbusMaster (ErrorCode,ComC1,115200,Count,3,B_Axis_Degrees(Count),&H103,1,1,10,0) 'Use Modbus command to retrieve Thermistor Celsius from string ModbusMaster (ErrorCode,ComC1,115200,Count,3,Celsius(Count),&H107,1,1,10,0) 'Delay before proceeding to next reading Delay (1,1,Sec) Next 'Call Table to store Data CallTable Test NextScan EndProg 22 | CRBASIC PROGRAMMING | GEOKON...
