Flashback Friday! RSLogix 5 Sum Integer File using FAL

Today I’m highlighting PLC-5 code I wrote and published twelve years ago using RSLogix 5.

The year was 2002, and my client needed to calculate a running average based on file of integer values he had been collecting.

The first step in doing this was to sum all those integer values together, and this is the simple code I put together to show him how to accomplish that task using the FAL instruction in the PLC-5.

Posted on my original website back on October 11th, 2002, you can now find this article and link to the RSLogix 5 RSP program file HERE on The Automation Blog:
