NOTE
If you use the protection-interface module USART-AV-2LDFO for distances under 30 km, then connect
2 attenuators 7XV5107-0AA00. To continue using the duplex LC plugs, attach both attenuators to one end
of the remote connection (see Figure 4-7).
Ethernet Modules
Operation of Ethernet Modules
The Ethernet modules of the SIPROTEC 5 series can be operated optionally with or without integrated switch
function. This applies for the electrical as well as the optical module. This function can be selected via the
parameterization. It is not necessary to make any indication in the order. The optical Ethernet modules are
compatible with the EN100 modules of the SIPROTEC 4 series. If the RSTP protocol or the HSR protocol is
active, the optical modules of the SIPROTEC 4 series and the SIPROTEC 5 series can be operated in a ring.
When using SIPROTEC 4 devices with module firmware ≤ V4.06 and SIPROTEC 5 devices, the maximum allow-
able number of participants is 30 devices. When using SIPROTEC 4 devices with module firmware ≥ V4.07 and
SIPROTEC 5 devices, the maximum allowable number of participants is 40 devices. When using SIPROTEC 5
devices, the maximum allowable number of participants is 40 devices.
Figure 4-8 shows operation of the Ethernet modules with integrated switch function. All devices of a station
are shown which are connected to one another by means of optical fibers. The devices form optical rings. In
addition, 2 switches are used on the substation controller for the SICAM PAS. The 2 switches take the require-
ments for the redundancy into account.
Additional participants with electrical interfaces can also be connected to the SICAM PAS (for example, the
DIGSI 5 control PC). An external switch is sufficient. Optical communication modules are primarily used for this
topology, as there can be substantial distances between the devices.
If the Ethernet modules are installed in expansion modules with a CB202 PCB assembly, the power supply can
be provided with an independent battery. The integrated switch can maintain its function when the device is
switched off. The data are transmitted in optical and electric rings. This prevents opening of the ring. The ring
continues to operate when 1 or more devices are switched off.
