Design
The DP/DP coupler is installed in a compact, 40 mm wide casing.
The module can be installed (vertically when possible) on a standard rail with no
gaps being necessary.
The coupler is attached to each PROFIBUS-DP network via an integrated 9-pin
sub-D connector.

Configuration Example of the DP/DP Coupler
How the DP/DP Coupler Works
The DP/DP coupler permanently copies output data of one network to the input
data of the other network (and vice-versa).
Parameter Assignment
The PROFIBUS-DP addresses are set using two DIP switches on the top of the
device. The configuration is set using the GSD file and the configuration tool of the
attached PROFIBUS-DP master. The data length is set with the relevant
configuration tool.
