Internal Variables 

You may have been wondering if a technician at a computer can “drill” into any device around the plant to view its internal operation using the same single software. With a system based on EDDL it is easy. The information provided here includes many examples of internal variables in simple and sophisticated (complex) devices and serves to explain how the device manufacturers make it easy to verify their devuce and troubleshoot its application from any system.

Plants have hundreds or thousands of devices of different types from different manufacturers which they must be able to confirm operate correctly.

Visualization of internal device variables can be done using handheld field communicator or intelligent device management software based on EDDL, whichever suits the task at hand best.

EDDL technology makes device viewing easier thanks to helpful graphics. The result is tasks completed faster.

What internal variable visualization, printing, and export etc. is possible for intelligent devices is not well understood and will therefore be explained in technical white papers and videos below. The importance of EDDL for internal variables is also explained.

EDDL technology supports small portable field communicators for easy configuration in the field, there is no other way to achieve a comparable result
