1.3 Communication services
CP 443-1 Advanced (GX30)
16 Manual, 03/2019, C79000-G8976-C256-05
The CP supports the following communication services:
●
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
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 (Isochronous Real Time) with IRT option "high performance"
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 us
ing IRT communication, no media redundancy is supported.
– Shared device
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.
●
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
requiring laborious programming
– Vendor-independent, plantwide engineering
Note
PROFINET CBA versus security function
If yo
u use PROFINET CBA, you cannot enable the CP for the "Security" functionality.
●
S7 communication with the following functions:
– PG functions
– Operator monitoring and control functions
– Data exchange over S7 connections
