Process Images
The tree view gives the process images for the tasks and/or devices below the various configurations.
If you select the process images shown in the example, on the right-hand side you will see the corresponding dialogue with more detailed information on the process image. The process image appears beneath, with a list of all linked and unlinked I/O variables.
”General” Dialogue
Name
Name of Process Image
Type
Defines whether process image functions as a master or a slave after linking (see alsoMapping Types).
Id
Gives the identification number of the process image.
Comment
User-defined comments field.
”Size / Offset” dialogue
Input Size
Size of the Input area in the generated process image.
Input Offset
It is possible to enter a start offset for the input range (if applicable, depends upon the device).
Output Size
Size of the Output area in the generated process image.
Output Offset
It is possible to enter a start offset for the output range (if applicable, depends upon the device).
”Input” / ”Output” Dialogue
The process image area in byte-size, hexadecimal form is shown in the Input / Output dialogue (and as symbols in its own column, if the ”Show Characters” option has been selected).
When displaying process images of devices with a mixed I/O area in the DPRAM (e.g. Beckhoff C1220 Lightbus card) output values are also shown reversed at the input.
Further information on process images and their links is given under Mappings.
