NOTE
Both jumpers must always be plugged in the same way !
Jumper X90 has currently no function. The factory setting is 1-2.
The terminating resistors can also be connected externally (e.g. to the connection module). In this case, the
terminating resistors located on the RS485 or PROFIBUS interface module or directly on the PCB of the
processor board C-CPU-2 must be de-energized.
