Hi, I am new to Labview programming. I am trying to program a SR630 16 Channel Thermocouple Reader to scan multiple channels and output the data into Excel. The driver I downloaded from NI contains a SR630 Example-Scan.VI that scans only one channel and outputs one line of result. How do I modify the drivers to scan multiple channels and export all the data to Excel?
I bypassed the SR630 buffer download by inserting a While loop with a Stop button and a 30 second timer delay, which encloses five Read Channel Measure.VIs, one for each channel I want to measure over time. The values were feed into an array and transferred to Excel using Write to Spreadsheet File.VI. Thi
s works except the programs seems to drop the GPIB address after the 7th or 8th measurement and I obtain an error code: -1073807339. The scanning rate was only every 30 seconds, quite slow. I also have frequent problems terminating the GPIB address from the last run even when I run SR630 Close.VI separately.
I am runing on a Dell Latitude CPt laptop, 600 Mhz Cpu, and a newly purchased PCMCIA-GPIB card from National Instruments.
Any suggestions on how to solve these problems would be greatly appreciated. I need to solve it by next Tuesday because I need it for my business trip. Thank you very much. David Ching
