Process Images And Process Image Partitions; Process Image - Overview - Siemens SIMATIC S7-1500 System Manual

You can, for example, find the assigned addresses:
• In the device view of the SINAMICS Integrated, in the Inspector window, on the General
tag under frame configuration
• In the network view when you select the network; the addresses are then displayed under
Address overview in the Inspector window

Process image - overview

Process image input and process image output
The process image input and output is an image of the signal states. The CPU transfers the
values from the input and output modules to the process image input and output. At the start
of the cyclic program, the CPU transfers the process image output as a signal state to the
output modules. The CPU then transfers the signal states of the input modules to the process
image inputs.
Advantages of the process image
A process image accesses a consistent image of the process signals during cyclic program
execution. If a signal state at an input module changes during program execution, the signal
state is retained in the process image. The CPU does not update the process image until the
next cycle.
Consistency of the process image
When the process image is updated, the SIMATIC Drive Controller accesses the data of each
submodule as consistent data. This behavior is identical to the modular SIMATIC S7-1500
CPUs.
The maximum data width that is accessed as consistent data for each submodule depends on
the IO system. For PROFINET IO, for example, this data width is 1024 bytes.
