• >Assign HTTPPage = jsdata.cgi
• >Assign HTTPSitename = "Well Monitor"
• >Assign HTTPUsername:Password = admin:pw

• If HTTPReplyCode == 200
• // process received data
• Else
• // no data received
• EndIf

• The ScanEngine Explorer script is instructed to run every 6 seconds.

• Every time it runs, it will send an http FETCH to the IP assigned to the PIC board, for the webpage I named “jsdata.cgi” which is what I named a webpage in the PIC

• The script tests the reply code, such that it can execute different code when the PIC responds vs when there is no response

• The modtronix base web server function will respond to http fetch requests. The code set in the modtronix PIC should include a web page with embedded macros to place latest measured values in an http fetched response.
