Figure 4-8
Operation of Ethernet Modules with an Integrated Switch Function
Figure 4-9 shows the operating mode without integrated switch function. Optionally, the 2nd connection can
be connected to the 2nd switch. This connection is shown with a dashed line in Figure 4-9. The IP communica-
tion is established using the 1st connection here. If this connection fails, the system changes over to the 2nd
connection within a few milliseconds. The IP connection is retained practically without interruption using the
2nd switch. This hot-standby connection redundancy increases the availability in such configurations, as
shown in the following figure. The information on failure of the protection connection is transmitted to the
substation automation technology.
