Configuration and operation
6.7 PROFINET IO mode
CP 443-1 (EX30)
54 Manual, 03/2019, C79000-G8976-C255-05
You will find further information on this in the system descriptions of PROFINET IO /16/
(Page 85) /17/ (Page 85).
Note
Reconfiguration - behavior on startup
After reconfiguring an IO device for prioritized startup, the first startup takes place in the
normal time without being prioritized. All subsequent startups will then be completed in the
reduced time.
Note
Inclusion in the MRP ring topology impractical
Including an IO device with prioritized startup in a ring topology with media redundancy
serves no practical purpose since the ring is interrupted at each device change.
IRT communication: Types of synchronization
Within an IRT domain (Isochronous Real Time), you can use the CP for IRT communication.
The CP supports IRT communication with the IRT option "high-performance". The IRT option
"high-performance" optimizes data traffic as the result of topology planning.
Note: The IRT option "high flexibility" is now only supported when a CP EX20 is replaced.
You specify the required synchronization parameters in the "Synchronization" parameter
group of the PROFINET interface.
Note
Requirements for configuration
Configuration for IRT communication is only possible with STEP 7 V5.5.x.
Operating PROFINET IO devices with a current firmware version
Using current firmware versions
For the PROFINET IO devices listed below, you should use the current firmware versions to
operate the CP.
● IM151-3PN with order number 6ES7151-3AA20-0AB0
● IM151-3PN with order number 6ES7151-3BA20-0AB0
You will find the current firmware versions on the Internet under the following entry ID:
