7.8 Programming

Short Cut is the best source for up-to-date datalogger programming code.

Programming code is needed,

•

when creating a program for a new datalogger installation

•

when adding sensors to an existing datalogger program

If your data acquisition requirements are simple, you can probably create and

maintain a datalogger program exclusively with Short Cut. If your data

acquisition needs are more complex, the files that Short Cut creates are a great

source for programming code to start a new program or add to an existing

custom program.

Short Cut cannot edit programs after they are imported and edited

in CRBasic Editor.

A Short Cut tutorial is available in Section 4, Quickstart. If you wish to import

Short Cut code into either Edlog or CRBasic Editor to create or add to a

customized program, follow the procedure in Appendix A.1, Importing Short

Cut Code into a Program Editor. Programming basics for CRBasic and Edlog

dataloggers are provided in the following sections. Complete program

examples for select dataloggers can be found in Appendix B, Example

Programs.

7.8.1 CRBasic Programming

The

SDI12Recorder() measurement instruction programs CRBasic

dataloggers (CR200(X) series, CR800 series, CR1000, CR3000, and CR5000)

to measure the CS470/CS471 sensor. This instruction sends a request to the

sensor to make a measurement and then retrieves the measurement from the

sensor. See Section 8.1, SDI-12 Commands, for more information.

When using a CR200(X), the

SDI12Recorder() instruction has the following

syntax:

SDI12Recorder(Destination,OutString,Multiplier,Offset)

For the other CRBasic dataloggers, the

SDI12Recorder() instruction has the

following syntax:

SDI12Recorder(Destination, SDIPort, SDIAddress, “SDICommand”,

Multiplier, Offset)

7.8.2 Edlog Programming

Edlog dataloggers read the CS470/CS471 using the

SDI-12 Recorder (P105)

instruction.

Please note that Edlog only allocates one input location for the

SDI-12

Recorder (P105) instruction. Seven input locations are required for the SDI-

M! command. The additional input locations need to be inserted manually

using the Input Location Editor. To get into the

Input Location Editor, select

Edit/Input Labels or press the F5 key. Once in the Input Location Editor,

do the following:
