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.

Please also observe the relevant description of possible 
image data provided in the EZ500/700 manual 
(MN05013003E) or in the EZSoft Help.
