The RS 485 interface can be modified to a RS232 interface by rearranging the
jumpers.
The jumper settings for the alternative interfaces RS232 or RS485 (according to
Figure 8-18) are listed in Table 8-21.
The jumpers X5 to X10 must be plugged in the same way!
Jumper presettings are in accordance with the ordered configuration.
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”,
dependent on the version (see Figure 8-17).

Replacing
Interface Modules
The interface modules can be replaced. Refer to Figure 8-17 for physical arrangement
of the modules. The order numbers of the replacement module can be found in
Appendix A, Section A.1.1.
Please note the following:
q
Only interface modules of devices with panel flush mounting and cubicle mounting
as well as of mounting devices with detached operator panel can be exchanged.
Interface modules of devices in surface mounting housings with double-level
terminals must be exchanged in our manufacturing centre.
q
Use only interface modules that can be ordered in our facilities
(see also Appendix A, Section A.1.1).
