Configuring Hardware; Assigning Parameters To Modules In A Fault-Tolerant Station - Siemens SIMATIC PCS 7 CPU 410-5H System Manual

Configuring hardware

You can create the AS bundle configurations with the PCS 7 wizard.
Another way of achieving a redundant hardware configuration is to initially assemble one
rack with all components to be implemented redundantly and to assign parameters to them.
The entire rack must then be copied and inserted. You adjust the network parameters
appropriately in the subsequent dialogs.
Special features in presenting the hardware configuration
In order to enable quick recognition of a redundant DP master system or PN/IO system,
each of them is represented by two parallel cables.
15.4.3

Assigning parameters to modules in a fault-tolerant station

Procedure
Assign all parameters of the redundant components identically, with the exception of
communication addresses.
The special case of CPUs
You can only set the CPU0 parameters (CPU on rack 0). Any values that you specify are
automatically allocated to CPU1 (CPU on rack 1). You can set the following values for
CPU1:
● Parameters of the DP interface (X1)
● Addresses of sync modules
● Parameters of the PROFINET IO interfaces
