Table 3-22 Replacing interface modules
The order numbers of the replacement modules can be found in the Appendix in Section A.1.
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 7UM62 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 Figures 3-1 and 3-2), or directly on the PCB of the C-CPU-2 board (see margin title „C-CPU-2
Processor Board“, Table 3-2).
Figure 3-9 shows the PCB of the C-CPU-2 with the layout of the boards.
The module for the RS485 interface is shown in Figure 3-10, the module for the Profibus interface in Figure 3-
11.
On delivery, the jumpers are set so that the terminating resistors are disconnected. Both jumpers of a module
must always be plugged in the same way.
