Please note the following:
• The interface modules can only be replaced in devices in flush mounting housing. Interface modules of
devices with surface mounting housing can only be replaced in our manufacturing centre.
• Use only interface modules that can be ordered ex-factory via the ordering code (see also Appendix, Section
A.1).
• You may have to ensure the termination of the interfaces featuring bus capability according to the margin
heading „RS485 Interface“.
Table 3-17 Exchangeable interface modules
The order numbers of the exchange modules can be found in the Appendix in Section A.1, Accessories.
RS232 interface
Interface RS232 can be modified to interface RS485 and vice versa (see Figures 3-11 and 3-12).
Figure 3-11 shows the location of the jumpers of the RS232 interface on the interface module.
Surface-mounted devices with fibre optics connection have their fibre optics module fitted in the console
housing on the case bottom. The fibre optics module is controlled via an RS232 interface module at the asso-
ciated CPU interface slot. For this application type the jumpers X12 and X13 on the RS232 module are plugged
in position 2-3.

Terminating resistors are not required for RS232. They are disconnected.
