In response to its customers’ needs for real-time debugging and analysis capabilities, Yokogawa has developed this enhanced version of its WideField3 software.

With the inclusion of Live Logic Analyzer, which is a near real-time logic analysis function, the upgraded WideField3 programming tool now has the capability to display data that shows the status of a PLC program as it runs on a sequence CPU module*. This improves work efficiency by enabling engineers to monitor a program’s execution status while they collect the program execution data. At any one time, the tool can display control data for up to 96 points. This data can be displayed graphically in a single window, enabling even maintenance personnel who are not familiar with PLC ladder programs to easily pinpoint problem causes. This improves the efficiency of debugging and problem analysis.

* Live Logic Analyzer supports the use of the F3SP71-4S and F3SP76-7S sequence CPU modules.

About the FA-M3 Series

In September 1989, Yokogawa entered the PLC market with the FA500 mid- to large-range model. In December 1992, Yokogawa introduced the FA-M3 range-free controller series to cover the full range, from small to large, and the latest FA-M3V was released in November 2010. (The V is from the French word vitesse, which means speed.)
