The DP/DP coupler continuously copies the output data from one network to the input data of the other network (and vice versa).

Functions

• Data exchange of up to 244 byte of input and output data of which up to 128 byte can be consistent
• Up to 16 input/output ranges for exchanging data
• If one side fails, the outputs on the other side maintain the previous value
• Support of DPV1 with full diagnostics
• Adjustment of DP/DP coupler either via switch or STEP 7
• Different baud rate settings are possible
• Electrical isolation between the two DP networks
• Power is supplied to both sides

Parameter assignment

The PROFIBUS DP addresses are set via two DIP switches on the top of the coupler.

The coupler is configured either with STEP 7 or with a configuring tool which integrates the DP/DP coupler with the help of a GSD file.

The data length is adjusted with the corresponding configuring tool.
