Communications are a large part of the vast majority of industrial systems. While designing these systems, you’ll find the need to test them to check their good working without relying on actual hardware.

The solution Siemens offers is PLCSim Advanced, a powerful PLC simulator that integrates a virtual network adapter for external communications.
