2 Requirements for Use

2 Requirements for Use
The CP 443-5 Extended V 6.1 described here is supported by all CPU operating
systems in the versions listed in Tables 2-1 and 2-2.
2.1

Use with the Current CPU Types

Limits and Conditions
To use the CP type described here, the following limits and constraints apply within
a rack:
S Number of operable CPs: 14
S Max. number of external DP chains (CP as DP master) : 10
Notice
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
S
PROFINET IO controllers (CP 443-1 Advanced) - maximum 4
S
DP masters (CP 443-5 Extended) - maximum 10
S Multicomputing is supported (except with CiR and H systems)
System Environment
The CP 443-5 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
443-5 Extended V 6.1 with the various CPU types: The following characteristics
are listed:
S CPU type, order number and version
S Option of multicomputing
S The number of CPs that can be operated with one CPU
S The maximum number of external DP chains of an S7 station;
S 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).
S Whether the CPU supports SYNC/FREEZE functionality (SFC11) via the CP.
S Whether the CPU supports the activate / deactivate (SFC12) DP functionality
via the CP.
