Appendix A. CRBasic Programming Instructions DNPUpdate Determines when the DNP slave will update arrays of DNP elements. Specifies the address of the DNP master to send unsolicited responses. Syntax DNPUpdate(DNPAddr) DNPVariable Sets up the DNP implementation in a DNP slave CR3000. Syntax DNPVariable(Array, Swath, Object, Variation, Class, Flag, Event Expression, Number of Events) ModBusMaster Sets up a datalogger as a ModBus master to send or retrieve data from a ModBus slave. Syntax ModBusMaster(ResultCode, ComPort, BaudRate, ModBusAddr, Function, Variable, Start, Length, Tries, TimeOut) ModBusSlave Sets up a datalogger as a ModBus slave device. Syntax ModBusSlave(ComPort, BaudRate, ModBusAddr, DataVariable, BooleanVariable) A.19 Calibration Functions Calibrate Used to force calibration of the analog channels under program control. Syntax Calibrate(Dest, Range) (parameters are optional) FieldCal Sets up the datalogger to perform a calibration on one or more variables in an array. Syntax FieldCal(Function, MeasureVar, Reps, MultVar, OffsetVar, Mode, KnownVar, Index, Avg) FieldCalStrain Sets up the datalogger to perform a zero or shunt calibration for a strain measurement. Syntax FieldCalStrain(Function, MeasureVar, Reps, GFAdj, ZeromV/V, Mode, KnownRS, Index, Avg, GFRaw, uStrainDest) LoadFieldCal Loads values from the FieldCal file into variables in the datalogger. Syntax LoadFieldCal(CheckSig) 525
