1.3 Communication services

1.3 Communication services
The CP supports the following communication services:
● PROFINET IO controller
PROFINET IO allows direct access to PROFINET IO devices over Industrial Ethernet.
PROFINET IO can only be used via the ports of the PROFINET interface.
– Prioritized startup
– IRT communication (Isochronous Real Time) with IRT option "high performance"
– Shared device
● PROFINET CBA
Use of a SIMATIC S7400 for Component based Automation on the basis of the
PROFINET standard of the PNO. This standard allows:
– Component technology in automation
– Communication between intelligent devices is configured graphically instead of
– Vendor-independent, plantwide engineering
● S7 communication with the following functions:
– PG functions
– Operator monitoring and control functions
– Data exchange over S7 connections

The CP supports prioritized startup. Per PROFINET IO controller, a maximum of 32
PROFINET IO devices can be configured that support prioritized startup. Of these 32
IO devices, simultaneous startup times with values as low as 0.5 s can be achieved by
up to 8 IO devices.
IRT communication with the IRT option "high-performance" is possible with
PROFINET IO. The IRT option "high-performance" optimizes data traffic as the result
of topology planning.
Note: IRT with the option "high flexibility" is now only supported when a CP GX20 is
replaced.
Note
IRT communication or MRP
If you are using IRT communication, no media redundancy is supported.
As a PROFINET IO controller, individual submodules of an IO device can be assigned
to the CP. Read the information in /19/ (Page 122) regarding configuration of
PROFINET IO systems and shared IO devices.

Note
PROFINET CBA versus security function
If you use PROFINET CBA, you cannot enable the CP for the "Security" functionality.
