Restrictions of security with VMware vSphere Hypervisor (ESXi)

When you use the virtualization platform VMware vSphere Hypervisor (ESXi), you must
change the policy exception to communicate over TCP/IP.
Remedy
Accept the "Promiscuous mode and "Forged transmit" options for the Virtual Switch of the
ESXi.
NOTICE
Restrictions of security
For security reasons, Promiscuous mode is disabled by default.
If you accept the Promiscuousmode, the real Ethernet adapter even receives telegrams
that are not addressed to it.

8.12 Error with overflow of cyclical events and motion OBs
If your simulation contains cyclic interrupts, the queue of PLCSIM Advanced may overflow
for cyclic events and for motion OBs. Due to the execution speed of PLCSIM Advanced
compared to real hardware, the time required to create the diagnostics buffer entry may be
longer than the time until the next cyclic interrupt.
In this case, an additional entry is placed in the queue, causing another overflow. In the
event of an overflow, PLCSIM Advanced provides visual information in the form of
diagnostics buffer messages and a red error icon in the project tree.
