TwinCAT System Manager: Real Time Configuration

Process Images

The tree view gives the process images for the tasks and/or devices below the various configurations.


Process Images 1:


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.

Input Offset

It is possible to enter a start offset for the input range (if applicable, depends upon the device).

”Input” / ”Output” Dialogue

Process Images 4:

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.
