6.2 CRBasic PakBus Dataloggers

The CR205 is a CRBasic programmed, PakBus compatible datalogger. Soon to

come is CSI’s full featured, CRBasic programmed, PakBus datalogger - the

CR1000.

6.2.1 SendGetData

Purpose

The SendGetData instruction is used in remote CR200 Series dataloggers to

send an array of values to the host datalogger, and/or retrieve an array of data

from the host datalogger. A TimeUntilTransmit instruction is required to

control the timing of the SendGetData instruction allowing it to transmit in the

time slot assigned by the host P193 instruction. For a more complete program

example, see Appendix F.

Example

Public TimeUntilTx

…..

TimeUntilTx = TimeUntilTransmit(1) ' 1 = RF, 2 = RS-232

…..

If TimeUntilTransmit(1) = 0 then ' time to communicate

SendGetData (Response, Control(),Measurements(),1,1,1,00000)

Endif

Syntax

SendGetData (ResponseDest, GetData, SendData, Port, HostAddr, RouterAddr,

Security)

Remarks

The host datalogger must be a CR10XPB, CR510PB, or CR23XPB datalogger

(CR200 to CR200 data transfer is not supported).

Parameters

• ResponseDest

The ResponseDest parameter is the variable in which a response code for

the transmission will be stored. The response code indicates whether or not

the transmission was successful. The codes that can be returned are:

Code Description

0 Successful

-1 Response received but permission denied

-2 Response received but insufficient resources

1, 2..n The number of timeouts waiting for a response

1 2 ... 46 47 48 49 50 51 52 53 54 55 56 ... 123 124
