Page 29: Grounds
A good earth (chassis) ground will minimize damage to the data logger and sensors by providing a low-resistance path around the system to a point of low potential. Campbell Scientific recommends that all data loggers be earth grounded. All components of the system (data loggers, sensors, external power supplies, mounts, housings) should be referenced to one common earth ground.

Page 92: Working With Data
16. Working with data 16.1 Default data tables By default, the data logger includes three tables: Public, Status, and DataTableInfo. Each of these tables only contains the most recent measurements and information. The Public table is configured by the data logger program, and updated at the scan interval set within the data logger program.
Page 93: Collecting Data
16.2 Collecting data The data logger writes to data tables based on intervals and conditions set in the CRBasic program (see Creating data tables in a program (p. 85) for more information). After the program has been running for enough time to generate data records, data may be collected by using data logger support software.

Page 104: Data Memory
Measurement data is primarily stored in data tables within serial flash. Data is usually erased from this area when a program is sent to the data logger. Final-data memory for the CR300 series is organized in 4 KB sectors. Each sector is rated for 100,000 serial flash erases.
Page 105: Flash Memory
When writing to files under program control, take care to write infrequently to prevent premature failure of serial flash memory. Internal chip manufacturers specify the flash technology used in Campbell Scientific CPU: drives at about 100,000 write/erase cycles. While Campbell Scientific's in-house testing has found the manufacturers' specifications to be very conservative, it is prudent to note the risk associated with repeated file writes via program control.

18.2.1 Voltage ranges for current measurements The data logger measures the current through the use of a 100 Ω resistor. Thus, like a single- ended voltage instruction, it requires a voltage range option. In general, use the smallest fixed- input range that accommodates the full-scale output of the transmitter. This results in the best measurement accuracy and resolution.

Page 118: Pulse Measurements
18.5 Pulse measurements The output signal generated by a pulse sensor is a series of voltage waves. The sensor couples its output signal to the measured phenomenon by modulating wave frequency. The data logger detects the state transition as each wave varies between voltage extremes (high-to-low or low- to-high).

Page 124: Communications Protocols
19. Communications protocols Data loggers communicate with data logger support software, other Campbell Scientific data loggers, and other hardware and software using a number of protocols including PakBus, Modbus, DNP3, and TCP/IP. Several industry-specific protocols are also supported. See also Communications specifications (p.
Page 125: General Serial Communications
Refer to the manual of the sensor or device to find its protocol and then select the appropriate options for each CRBasic parameter. See the application note Interfacing Serial Sensors with Campbell Scientific Dataloggers for more programming details and examples.
Page 126: Modbus Communications
How to Access Live Measurement Data Using Modbus Using Campbell Scientific Dataloggers as Modbus Slave Devices in a SCADA Network Because Modbus has a set command structure, programming the data logger to get data from field instruments can be much simpler than from some other serial sensors. Because Modbus uses a common bus and addresses each node, field instruments are effectively multiplexed to a data logger without additional hardware.
Page 127: About Modbus
Not only can intelligent devices such as microcontrollers and programmable logic controllers (PLCs) communicate using Modbus, but many intelligent sensors have a Modbus interface that enables them to send their data to host systems. Examples of using Modbus with Campbell Scientific data loggers include: ...
Page 128: Modbus Protocols
19.2.2 Modbus protocols There are three standard variants of Modbus protocols: Modbus RTU — Modbus RTU is the most common implementation available for Modbus. Used in serial communications, data is transmitted in a binary format. The RTU format follows the commands/data with a cyclic redundancy check checksum. NOTE: The Modbus RTU protocol standard does not allow a delay between characters of 1.5 times or more the length of time normally required to receive a character.
Page 129: Understanding Modbus Terminology
Campbell Scientific data loggers support Modbus RTU, Modbus ASCII, and Modbus TCP protocols. If the connection is over IP, Campbell Scientific data loggers always use Modbus TCP. Modbus server functionality over other comports use RTU. When acting as a client, the data...
Page 130: About Modbus Programming
Campbell Scientific data loggers can be programmed to be a Modbus client or Modbus server - or even both at the same time! This proves particularly helpful when your data logger is a part of two wider area networks.
Page 131: Function Codes
Different devices support different functions (consult the device documentation for support information). The most commonly used functions (codes 01, 02, 03, 04, 05, 15, and 16 ) are supported by Campbell Scientific data loggers. Most users only require the read- register functions. Holding registers are read with function code 03.
Page 132: Modbus Information Storage
In a 16-bit memory location, a 4-byte value takes up two registers. The Modbus protocol always refers to data registers with a starting address number, and a length to indicate how many registers to transfer. Campbell Scientific uses 1-based numbering (a common convention for numbering registers in ModbusClient() equipment) in the instruction.
Page 133: Coils
19.2.7.2 Coils Discrete digital I/O channels in Modbus are referred to as coils. The term coil has its roots in digital outputs operating solenoid coils in an industrial environment. Coils may be read only or read/write. A read only coil would be a digital input. A read/write coil is used as an output. Coils are read and manipulated with their own function codes, apart from the registers.

Long holding it. 32-Bit floating point 32-bit floating point values use 2 registers each. This is the default FLOAT data type in Campbell Scientific data loggers. Select the appropriate ModbusOption to avoid post-processing.
Page 135: Error Codes
19.2.8.1 Error codes Modbus defines several error codes, which are reported back to a client from a server. ModbusClient() displays these codes as a negative number. A positive result code indicates no response was received. Result code -01: illegal function The illegal function error is reported back by a Modbus server when either it does not support the function at all, or does not support that function code on the requested registers.

Page 190: Avoiding Time Skew
22.3.3 Avoiding time skew Time skew between consecutive measurements is a function of settling and integration times, ADC, and the number entered into the Reps parameter of CRBasic instructions. A close approximation is: time skew = reps * (settling time + integration time + ADC time) + instruction setup time where ADC time equals 170 µs, and instruction setup time is 15 µs.

Page 202 effect when a large current is discharged nearby. The creation of an electromagnetic pulse can induce a surge that damages attached electronic devices. Another way ground loops affect a system is by allowing ground current to flow between devices. This can be either a DC or AC effect. For various reasons, the voltage potential between two different points on the surface of the earth is not always 0 V.
Page 203: Severing A Ground Loop
22.10.3 Severing a ground loop To avoid or eliminate ground loops, when they are detected, requires severing the loop. Suggestions for severing ground loops include: Connect the shield wire of a signal cable to ground only at one end of the cable. Leave the other end floating (not connected to ground).
Page 204 Note that the geometry of the electrodes has a great effect on the magnitude of this error. The Delmhorst gypsum block used in the Campbell Scientific 227 probe has two concentric cylindrical electrodes. The center electrode is used for excitation; because it is encircled by the ground electrode, the path for a ground loop through the soil is greatly reduced.

Rapid sampling is required. Single-ended measurement time is about half that of differential measurement time. Sensor is not designed for differential measurements. Some Campbell Scientific sensors are not designed for differential measurement, but the drawbacks of a single-ended measurement are usually mitigated by large programmed excitation and/or sensor output voltages.
Page 207: Ground Potential Differences
Connect shield wires to the terminal nearest the terminals to which the sensor signal wires are connected. If offset problems occur because of shield or ground wires with large current flow, tying the problem wires into terminals next to terminals configured for excitation and pulse-count should help.
Page 208: Minimizing Electronic Noise
High-quality power regulators typically reduce noise due to power regulation. Using the 50 Hz or 60 Hz first notch frequency (f ) option for CRBasic analog input measurement instructions often improves rejection of noise sourced from power mains. The CRBasic standard deviation output instruction, StdDev(), can be used to evaluate measurement noise.
Page 209: Filtering To Reduce Measurement Noise
So, V = (V+ + V–)/2 or the voltage remaining on the inputs when V = 0. The total voltage on the V+ and V– inputs is given as V /2, and V – V /2, respectively. 22.11.4 Filtering to reduce measurement noise The data logger applies an adjustable filter to analog measurements, reducing signal components at selected frequencies.

Page 212: Minimizing Settling Errors
22.11.5.1 Measuring settling time Settling time for a particular sensor and cable can be measured with the CR300 series. Programming a series of measurements with increasing settling times will yield data that indicate at what settling time a further increase results in negligible change in the measured voltage. The programmed settling time at this point indicates the settling time needed for the sensor / cable combination.

Page 215: Measurement Accuracy Example
22.11.6.1 Measurement accuracy example The following example illustrates the effect percent-of-reading and offset have on measurement accuracy. The effect of offset is usually negligible on large signals. Example: Sensor-signal voltage: approximately 2500 mV CRBasic measurement instruction: VoltDiff() Programmed input-voltage range (Range) : mV 2 500 (±-100 to 2500 mV) ...
Page 216 Remedies include: Connecting power grounds to power ground terminals (G). Automatic offset compensation for single-ended measurements when MeasOff = False. Using MeasOff = True for better offset compensation. Programming longer settling times. Single-ended measurements are susceptible to voltage drop at the ground terminal caused by return currents from another device that is powered from the data logger wiring panel, such as another manufacturer's communications modem, or a sensor that requires a lot of power.
Page 217: Field Calibration
Avoiding preceding a very small voltage input with a very large voltage input in a measurement sequence if a single measurement instruction must be used. 22.12 Field calibration Calibration increases accuracy of a measurement device by adjusting its output, or the measurement of its output, to match independently verified quantities.
