Section 7. Installation 7.6.3.4 Using Variable Pointers A pointer is the memory address of a variable. Use a pointer as a convenient way to reference the memory location of a variable rather than referencing it by name. This is useful in a Function() instruction function when parameters are local to the function and changes to them have no effect on original arguments.

Page 198: Predefined Constants
Section 7. Installation Constants, in memory, are four-byte signed integers or floating point numbers of up to about 500 characters in length (length limited to the maximum command line length). (p. 576) CRBasic syntax does not have a provision for declaring a data type for a constant, so the compiler infers data type based on the format of the constant value expression, which is usually a single scalar.
Page 199: Declaring Aliases And Units

Page 200: Multi-Statement Declarations
Section 7. Installation Binary format (1 = high, 0 = low) is useful when loading the status of multiple flags or ports into a single variable. For example, storing the binary number &B11100000 preserves the status of flags 8 through 1: flags 1 to 5 are low, 6 to 8 are high.

Section 7. Installation Multi-statement declarations can be located as follows: Prior to BeginProg, • After EndSequence or an infinite Scan() / NextScan and before • EndProg or SlowSequence • Immediately following SlowSequence. SlowSequence code starts executing after any declaration sequence. Only declaration sequences can occur after EndSequence and before SlowSequence or EndProg.

Page 207 Section 7. Installation Data Output Processing Instructions Data-storage processing instructions (aka, "output processing" instructions) determine what data are stored in a data table.

Section 7. Installation 7.6.3.16 Programming Expression Types An expression is a series of words, operators, or numbers that produce a value or result. Expressions are evaluated from left to right, with deference to precedence rules. The result of each stage of the evaluation is of type Long (integer, 32 bits) if the variables are of type Long (constants are integers) and the functions give integer results, such as occurs with INTDV().

Page 225 Section 7. Installation argument TRUE is predefined in the CR6 operating system to only equal -1, so only the argument -1 is always translated as TRUE. Consider the expression Condition(1) = TRUE Then... This condition is true only when Condition(1) = -1. If Condition(1) is any other non-zero, the condition will not be found true because the constant TRUE is predefined as -1 in the CR6 system memory.
Page 226 Section 7. Installation Using TRUE or FALSE conditions with logic operators such as AND and OR, logical expressions can be encoded to perform one of the following three general logic functions. Doing so facilitates conditional processing and control applications: 1. Evaluate an expression, take one path or action if the expression is true (= –1), and / or another path or action if the expression is false (= 0).
Page 227: String Expressions
Section 7. Installation Logical Expression Examples The NOT operator complements every bit in the word. A Boolean can be FALSE (0 or all bits set to 0) or TRUE (-1 or all bits set to 1).

This standard deviation is calculated using Campbell Scientific's wind speed weighted algorithm. Use of the resultant mean horizontal wind direction is not recommended for straight-line Gaussian dispersion models, but may be used to model transport direction in a variable-trajectory model.

Section 7. Installation Note Cup anemometers typically have a mechanical offset which is added to each measurement. A numeric offset is usually encoded in the CRBasic program to compensate for the mechanical offset. When this is done, a measurement will equal the offset only when wind speed is zero; consequently, additional code is often included to zero the measurement when it equals the offset so that WindVector() can reject measurements when wind speed is zero.

Section 7. Installation 7.7.12.6.1 FieldCalStrain() Shunt Calibration Concepts 1. Shunt calibration does not calibrate the strain gage itself. 2. Shunt calibration does compensate for long leads and non-linearity in the resistive bridge. Long leads reduce sensitivity because of voltage drop. FieldCalStrain() uses the known value of the shunt resistor to adjust the gain (multiplier / span) to compensate.

Installation Measuring Multiple PRTs (PT100 Resistance() Basic-Circuit Series) If you connect only one PRT to a [U] [Ix] terminal configured for current excitation, the previous procedure serves well. However, if multiple PRTs are measured from a single excitation terminal, the sum of voltages output from all PRTs connected to one excitation terminal must not exceed 5000 mV, which is the input limit (InLim) for the CR6.

Section 8. Operation records could be collected since it took 50 ms, or 5 records, to stop the CPU from storing its 5 records beyond when the card was stopped. 8. Note that only the CRD: drive will keep storing until all its records are filled; the CPU: drive will stop when the programmed number of records are stored.
