A new OptoTutorial—Using the SNAP PAC REST API with Excel— helps you create a macro-enabled Microsoft Excel® worksheet that reads, writes, and charts values from a SNAP PAC R- or S-series controller.

One of the sample workbooks in the tutorial—Opto22_ReadingWritingSamples.xlsm—can be used as a development tool to generate API commands for your own custom code.

The tutorial’s download file is available at http://www.opto22.com/site/downloads/dl_drilldown.aspx?aid=4627.
