I am trying to add a feature to a PAC control/display package, and wondering if anyone out there has tried to do something similiar and/or can offer words of wisdom.
There is a desire to add an automatic screen capture of an overview screen displaying critical temperatures/pressures/etc and send it out via email. Currently an operator prints the screen at defined intervals, scans, then emails it.
What I am looking for is a way to automate or schedule a routine that would change PAC display runtime to the overview window and print the image (using a print-to-pdf application). We have an outside email system we can trigger to send the attachment, my confusion is how to force a change of the active window and then print/capture the image.
I have separately generated .csv files on demand for reporting of these values, but this customer is highly interested in a capture of the actual overview screen.
