Function
The DP/DP coupler continuously copies the output data of one network to the input data of
the other network (and vice versa).
● Exchange of a maximum of 244 bytes of input and output data, in each case with up to
128 bytes consistent
● Maximum of 16 input/output ranges for the exchange of data
● If one side fails, the outputs of the other side are held at the last value
● Support of DPV1 with full diagnostics
● The DP/DP coupler can be set either using switches or with STEP 7
● Different baud rate settings are possible
● Electrical isolation between the two DP networks
● Two-way power supply
Parameter assignment
The PROFIBUS DP addresses are set by using two DIL 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.
Ordering data
Ordering data Order no.
DP/DP coupler
To connect two PROFIBUS DP networks.

4.4.1 Connecting to PROFIBUSPA
DP/PA bus coupler
The DP/PA bus coupler is the link between PROFIBUS DP and PROFIBUS PA. This means
that it connects the process control systems with the field devices of process automation
(PA).
The following modules are available for the DP/PA bus coupling:
● DP/PA coupler Ex [ia] (6ES7 157-0AD82-0XA0)
● DP/PA coupler FDC 157-0 (6ES7 157-0AC83-0XA0)
● Interface module IM 153-2 (6ES7 153 2BA82-0XB0) for setting up a DP/PA link
