Problems can arise if a control is connected to an IP network, which contains
modules that are not running with a SIGMATEK operating system. With such
devices, Ethernet packets could be sent to the control with such a high fre-
quency (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 triggering the error
mentioned above.
