What is the difference between "normal routing" and data record routing?

  • Entry
  • Associated product(s)

You can send data to field devices over PROFIBUS from an Engineering Station that is connected to PROFINET. The field devices themselves do not have to support data record routing, because these devices do not forward the information content.

The data sent with data record routing includes the parameter assignment of the field devices participating (DP slaves) and also device-specific information (setpoint values and limit values, for example). In data record routing, the structure of the target address depends on the data content, that is to say on the DP slave for which the data is destined.

With the PG you can use data record routing to read and edit a parameter record already on the field device and send it to the field device if the PG/PC is already assigned as target slave to another subnet.

Data record routing is used, for example, when field devices of different manufacturers are operating in one network. The field devices are addressed for parameterization and diagnostics over standardized data records (PROFIBUS standard). Using a data record gateway, an Engineering Station with SIMATIC PDM can reach field devices several subnets away.

Support of data record routing
Data record routing is supported by SIMATIC PDM which must be installed on the Engineering Station.
Furthermore, there are applications in which STEP 7 automatically executes data record routing.

An Engineering System is connected to the PROFINET subnet and calls special PROFIBUS data records from a PROFIBUS DP slave. The PROFINET/PROFIBUS gateways are set automatically by STEP 7 in the "Go online" dialog.

  • Use the "S7 Routing" function for transferring data beyond network boundaries. In this case you can send data from a sender to a receiver over various networks. More information about the "S7 Routing" function is available in Entry ID 584459.
  • Data record routing by means of the backplane bus is not supported for an I slave. The data for these modules cannot be routed over the backplane bus.
