Division of the PC resources
The hypervisor technology divides the PC resources and assigns all resources required for
the control job exclusively to the SIMATIC S7-1500 Software Controller. Linux and Linux
applications have no access to these resources and the Software Controller has no access
to Linux resources.
The SIMATIC communication architecture allows secure and transparent communication
between Linux applications and the CPU:
● Local communication with the HMI or other Linux applications
● Controlled access to PROFINET modules for STEP 7 or HMI
● Controlled communication with external devices via Linux interfaces
The required resources are assigned during download of the STEP 7 configuration. This
enables you to customize the PC-based application in STEP 7 as needed to meet the
requirements of an automation solution.
