Data set routing
Availability
S7-400H CPUs as of firmware version 6.0 support data set routing. The CPUs must also be
configured in this or a higher firmware version for this.
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 need to support data set routing, since these devices do not
forward the included information.
