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.
