Communication Paths - Siemens Simatic S7-1500 Function Manual

Communication paths

Local and distributed communication
The following paths are open for communication between STEP 7 V15 or higher and the
instances of PLCSIM Advanced user interfaces:

Softbus
Softbus is a communication path via a virtual software interface.
The communication is limited to a local PC or a virtual machine. The advantage here is that
no data can be accidentally downloaded to a hardware CPU or communicate with real
hardware.
Selecting a communication interface
You program the communication interface via the user interfaces (API) or select them in the
Control Panel under "Online Access". The setting is valid for all generated instances. The
default setting is the communication via "PLCSIM" (Softbus).
Additional network settings are necessary for the distributed communication via the "PLCSIM
Virtual Ethernet Adapter" (TCP/IP), see Network addresses in the simulation (Page 66).
