Problems can arise if a control is connected to an IP network, which contains mod-
ules that do not contain a SIGMATEK operating system.
With such devices, Ethernet
packets could be sent to the control with such a high frequency (i.e. broadcasts), that
the high interrupt load could cause a real-time runtime error or runtime error.
By
configuring the packet filter (Firewall or Router) accordingly however, it is possible
to connect a network with SIGMATEK hardware to a third party network without trig-
gering the error mentioned above.
