Connecting PROFIBUS-DP to RS-232C

Design
Figure 2-18
The DP/RS-232C link consists of a compact 70 mm housing for standard rail
mounting. Ideally the module should be installed vertically. The modules can be
inserted one beside the other without gaps being necessary. The module is
attached to PROFIBUS-DP via a 9-pin sub-D female connector. The RS-232C
interface is implemented as a 9-pin sub-D connector.
