jhm0615 Posted April 22, 2010 Share Posted April 22, 2010 I have a remote temperature sensor that I am trying to monitor via the COM port. I have successfully written code in LabView that will do this but would like to perform this inside of an AutoIt script. Below is the code and console responses I have for AutoIt. As far as I can tell I am successfully accessing the COM port but beyond that it does not appear that it is working. The temp reading should be around 25c. Any help regarding this issue is greatly appreciated. ;Define variables Dim $h_instr = _viOpen("ASRL1::INSTR") ConsoleWrite("Instrument Handle obtained" & @CRLF & "$h_instr = " & $h_instr & @CRLF) ; Show the Session Handle _viSetAttribute($h_instr,$VI_ATTR_ASRL_BAUD,9600) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : _viSetAttribute($h_instr,$VI_ATTR_ASRL_BAUD,9600) = ' & _viSetAttribute($h_instr,$VI_ATTR_ASRL_BAUD,9600) & ' - - >Error code: ' & @error & @crlf) ;### Debug Console _viSetAttribute($h_instr,$VI_ATTR_ASRL_DATA_BITS,7) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : _viSetAttribute($h_instr,$VI_ATTR_ASRL_DATA_BITS,7) = ' & _viSetAttribute($h_instr,$VI_ATTR_ASRL_DATA_BITS,7) & ' - - >Error code: ' & @error & @crlf) ;### Debug Console _viSetAttribute($h_instr,$VI_ATTR_ASRL_PARITY,$VI_ASRL_PAR_ODD) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $h_instr,$VI_ATTR_ASRL_PARITY,$VI_ASRL_PAR_ODD) = ' & _viSetAttribute($h_instr,$VI_ATTR_ASRL_PARITY,$VI_ASRL_PAR_ODD) & ' - - >Error code: ' & @error & @crlf) ;### Debug Console _viSetAttribute($h_instr,$VI_ATTR_ASRL_STOP_BITS,$VI_ASRL_STOP_ONE) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $h_instr,$VI_ATTR_ASRL_STOP_BITS,$VI_ASRL_STOP_ONE) = ' & _viSetAttribute($h_instr,$VI_ATTR_ASRL_STOP_BITS,$VI_ASRL_STOP_ONE) & ' - - >Error code: ' & @error & @crlf) ;### Debug Console _viSetAttribute($h_instr,$VI_ATTR_ASRL_FLOW_CNTRL,$VI_ASRL_FLOW_NONE) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $h_instr,$VI_ATTR_ASRL_FLOW_CNTRL,$VI_ASRL_FLOW_NONE) = ' & _viSetAttribute($h_instr,$VI_ATTR_ASRL_FLOW_CNTRL,$VI_ASRL_FLOW_NONE) & ' - - >Error code: ' & @error & @crlf) ;### Debug Console dim $s_answer = _viExecCommand($h_instr,"*V01" & @CRLF,10000) ; 10 secs timeout ConsoleWrite("<Temperature is <" & $s_answer & ">" & @CRLF) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : _viExecCommand($h_instr,"*V01" & @CRLF,10000)) = ' & _viExecCommand($h_instr,"*V01" & @CRLF,10000) & ' - - >Error code: ' & @error & @crlf) ;### Debug Console Instrument Handle obtained $h_instr = 23345736 @@ Debug(27) : _viSetAttribute($h_instr,$VI_ATTR_ASRL_BAUD,9600) = 0 - - >Error code: 0 @@ Debug(30) : _viSetAttribute($h_instr,$VI_ATTR_ASRL_DATA_BITS,7) = 0 - - >Error code: 0 @@ Debug(33) : $h_instr,$VI_ATTR_ASRL_PARITY,$VI_ASRL_PAR_ODD) = 0 - - >Error code: 0 @@ Debug(36) : $h_instr,$VI_ATTR_ASRL_STOP_BITS,$VI_ASRL_STOP_ONE) = 0 - - >Error code: 0 @@ Debug(39) : $h_instr,$VI_ATTR_ASRL_FLOW_CNTRL,$VI_ASRL_FLOW_NONE) = 0 - - >Error code: 0 <Temperature is <0> @@ Debug(43) : _viExecCommand($h_instr,"*V01" & @CRLF,10000)) = 0 - - >Error code: 0 Thanks, James Link to comment Share on other sites More sharing options...
PsaltyDS Posted April 22, 2010 Share Posted April 22, 2010 Is "*V01" a valid QUERY for that device? How is that documented? Valuater's AutoIt 1-2-3, Class... Is now in Session!For those who want somebody to write the script for them: RentACoder"Any technology distinguishable from magic is insufficiently advanced." -- Geek's corollary to Clarke's law Link to comment Share on other sites More sharing options...
jhm0615 Posted April 22, 2010 Author Share Posted April 22, 2010 This is a valid command and comes straight from the manual for the unit. This is the same command I use with the LabView program and even have to add the return. To that end I have tried appending @CRLF, @CR, and ^m to the *V01 command but have had no luck within AutoIt. Now as to whether this is a Query, in the strictest since I do not believe so as the question mark is not used when I perform this operation in LabView. I have attached a screen capture of the LabView GUI in case that helps. Thanks for taking an interest in this James Link to comment Share on other sites More sharing options...

Thanks for taking an interest in this James Possibly not many people , certainly not me, have experience using the labview interface to a serial port using AutoIt. There are a couple of COM port udfs in example scripts although it would require learning a new approach. There is a link to my udf in my signature and the first post of the thread has links to the udf download and a rather simple example. It could be that the simple example, which is a limited terminal emulater, might get some respnse for you and if so it could be worth pursuing. Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

jchd Posted April 23, 2010 Share Posted April 23, 2010 (edited) People already have connected temp sensors on COM ports using AutoIt. As Martin said, this is a more pedestrian way, but it can help, even only temporarily. I have a small lab will lots of GPIB intruments that I control with the Visa interface (a very primitive non-payware version) over a slow dedicated Ethernet branch. But I only need to deal with GPIB stuff directly and never had to launch Labview, simply install the NI drivers for networked GPIB ENETs 10 & 100. It would be pointless anyway, since I only do repair and calibration. My calibration procedures are in AutoIt, not LabView. I'm currently very busy with completely other stuff, so that lab is currently power off. I'm afraid I can't help you much on this. I'll try to re-power a few things to see if I can be of help but I don't promise much. Edit: I've reinstalled drivers. Everything I can power up (wife sleeping nearby) works but I couldn't find instrument drivers for the only serial instruments I have handy (Thunderbolt GPS timebases) and I ain't in the mood of developping such driver anytime soon.

jhm0615 Posted April 26, 2010 Author Share Posted April 26, 2010 Martin, Thanks for the information I was able to use your UDF to communicate with device and am trying to add it into an existing script. James Link to comment Share on other sites More sharing options...
