Data set routing
Routing and data set routing
Routing is the transfer of data beyond network boundaries. You can send information from a
transmitter to a receiver across several networks.
Data set routing is an expansion of S7 routing and is used, for example, in SIMATIC PDM.
The data sent through data record routing include the parameter assignments of the
participating communication devices and device-specific information (for example, setpoint
values, limit values, etc.). The structure of the destination address for data set routing
depends on the data content, in other words, it is determined by the device for which the
data is intended.
The field device itself does not have to support data set routing, since these devices do not
forward the received information.
Data set routing
The following figure shows the engineering station accessing a variety of field devices. The
engineering station is connected to the CPU via Industrial Ethernet in this scenario. The CPU
communicates with the field devices via the PROFIBUS.
