Use in Fault-tolerant Systems
1)
With a CP 443-5 Extended, you have the following options in a fault-tolerant (H)
system:
S
Operating fault-tolerant S7 connections with communication services configured
on one partner
or
S
You can implement redundant and single peripheral structures (mixed mode is
also possible).
You will find more detailed information about the possible operating and structural
options in the “SIMATIC S7-400H Programmable Controller Manual, Fault-tolerant
Systems”.
If the CP 443-5 Extended is used in a fault-tolerant S7-400H system, the following
communications services can also be used on single (non-redundant) connections:
S
S7 connection (including PG functions and PG routing)
S
S5-compatible communication (SEND/RECEIVE interface) on FDL connections
S
Time-of-day distribution
