Siemens PLCSIM Virtual Ethernet Adapter

IP address
At the PLCSIM Virtual Ethernet Adapter you assign a static IP address or obtain an IP
address via DHCP (default).
MAC address
A randomly generated MAC address is assigned to the PLCSIM Virtual Ethernet Adapter
during its installation.
PLCSIM Advanced only uses MAC addresses that are designated as "locally administered"
(bit 2 in LSB).
The Siemens-specific prefix is: 02-1B-1B
Three bytes follow, which are determined at random.
Storage location
This MAC address is stored in the registry key "PlcsimvminiMacAddress".
You can overwrite this value.

PLCSIM Advanced instances

Detect CPUs and instances
If Ethernet interfaces of CPUs and PLCSIM Advanced instances are mixed in a network, the
instances can be recognized by the "PLCSIM" suffix on the station type.
