Requirements For Use; Use With The Current Cpu Types - Siemens SIMATIC NET CP 443-5 Extended Manual

Application and functions

1.3 Requirements for use

1.3 Requirements for use
The CP 4435 Extended described here is supported by all CPU operating systems in the
versions listed in Tables 2-1 and 2-2 below.
1.3.1

Use with the current CPU types

Configuration limits
To use the CP type described here, the following limits and constraints apply within a rack:
● Number of operable CPs: 14
● Max. number of external DP lines (CP as DP master): 10
Note
The number CPs that can be operated as DP masters depends on the number of CP
443-1 Advanced modules operated as PROFINET IO controllers in the S7-400 station. In
total, 10 CPs can be operated as:
• PROFINET IO controllers (CP 443-1 Advanced) - maximum 4
• DP masters (CP 443-5 Extended) - maximum 10
● Multicomputing is supported (except with CiR and H systems)
System environment
The CP 4435 Extended is supported by the S7-400 CPUs and CPU operating systems with
the order numbers and versions listed in the table below.
From the table, you can see which functionality is supported when you use the CP 4435
Extended V 6.1 with the various CPU types. The following characteristics are shown:
● CPU type, order number and version
● Option of multicomputing
● The number of AG_SEND or AG_RECV calls on the SEND/RECEIVE interface that can
be active at the same time (data exchange on FDL connections over PROFIBUS and
corresponding connections over Industrial Ethernet)
● CPU support for SYNC/FREEZE functionality (SFC11) via the CP
● CPU support of the "activate / deactivate DP functionality (SFC12)" via the CP
● CPU support of the functionality for "identifying the bus topology in a DP master system"
(SFC103) via the CP
12
