8.5 Process image
The process image is an object on tab Resources in the Object Organizer.
•
Process images are maps of the statuses of the inputs/outputs of all system organization
units used in the automation system at a particular time.
Tip!
•
The process image of the Lenze automation systems consists of the I/O statuses of the
system organization units entered into the PLC configuration by the user. (Also refer chapter
8.6, “ PLC configuration” ,
^ 8-23 )
•
Some system organization units are always processed by the runtime system.
These system organization units are assigned to a specific (system) task with a fixed time
interval.
(refer associated system organization unit description in the manual for the relevant Lenze
automation system.)
•
Double-click the object Process image in the Object Organizer to open the dialog box
Process image.
The dialog box Process image shows in which task the process image of a
system organization unit is generated or written.
Note!
As a consequence of a system organization unit not listed in this dialog box, no process image will
be created, and the system organization unit will not be called or processed either!
Dialog box Process image provides a shortcut to establishing why the data of a system organization
unit are not processed.
A process diagram for the outputs of a system block will only be generated if the outputs are
accessed in writing mode.
If the outputs are accessed in reading mode, the action will not appear in the process diagram.
