Profibus
The terminating resistors can also be connected externally (e.g. to the connection
module) as illustrated in Figure 8-23. In this case, the terminating resistors located on
the RS485 or the Profibus interface module must be disconnected.

Analog Output
Module
The analog output module AN20 is provided with 2 isolated channels with a current
range from 0 to 20 mA (unipolar, maximum 350
Ω).
The mounting location on the processor circuit board C–CPU–2 is “B” and/or “D”, de-
pendentontheversion(seeFigure8-19).
