General notes on working with image data
When writing to image data, it must be remembered that an
image (e.g. inputs, outputs,... ) used in the EZ700/EZ800/EZD
program is also written cyclically by the actual program. The
only image data that is unchanged is the data that is not used
in the program and is therefore not overwritten in the program
cycle. This operating principle also means that an image
written via EZ-LINK, such as output data is only then output at
the physical outputs of the EZ700/EZ800/EZD when the
control relay is in Run mode.

image data provided in the EZ500/700 manual
(MN05013003E) or in the EZSoft Help.
