The order numbers of the replacement modules can be found in the Appendix in Section A Ordering Informa-
tion and Accessories.
EN100 Ethernet Module (IEC 61850)
The Ethernet interface module has no jumpers. No hardware modifications are required to use it.
Termination
For bus-capable interfaces a termination is necessary at the bus for each last device, i.e. terminating resistors
must be connected. With the 7VE61 and 7VE63 device, this concerns the variants with RS485 or PROFIBUS
interfaces.
The terminating resistors are located on the RS485 or Profibus interface module, which is on the C–CPU–2
board ((1) in Figure 3-2 and Figure 3-3), or directly on the PCB of the C-CPU-2 board (see margin title “C-CPU-2
Processor Board”, Table 3-7).
Figure 3-8 shows the PCB of the C-CPU-2 with the layout of the boards.
The module for the RS485 interface is shown in Figure 3-9, the module for the Profibus interface in
Figure 3-10.
On delivery the jumpers are set so that the terminating resistor are disconnected. Both jumpers of a module
must always be plugged in the same way.

The terminating resistors can also be connected externally (e.g. to the terminal block), see Figure 3-5. In this
case, the matching resistors located on the RS485 or PROFIBUS interface module or directly on the PCB of the
C-CPU-2 board of must be disabled.
