What is PROFINET IO?
PROFINET IO is the open transmission with realtime functions defined in
accordance with the PROFINET standard.
The standard defines a manufacturer-independent communication, automation and
engineering model.
Industrial quality connection designs are available for wiring the PROFINET
components.
•
PROFINET does not use the hierarchical PROFIBUS master-slave principle. A
provider-consumer principle is used instead. The planning process specifies
which modules of an I/O device will be subscribed to an I/O controller.
•
The quantities are extended in accordance with the options offered by the
PROFINET IO. Parameter limits are not exceeded during configuration.
•
The transmission rate is 100 Mbps.
•
The user view during configuration is generally the same as that on the
PROFIBUS DP (STEP 7
→
HWCONFIG is used for configuration).
Structure of a PROFINET IO network
The figure below illustrates a typical PROFINET IO network structure. Existing
PROFIBUS slaves can be integrated by an IE/PB link.
