I/O configuration variants of the fault-tolerant system
I/O configuration variants
The following configuration variants are available for the input/output modules:
● In stand-alone operation: single-sided configuration.
In the single-sided configuration, there is a single set of the input/output modules (single-
channel) that are addressed by the CPU.
● In redundant operation: Single-channel switched configuration with enhanced availability.
In the single-channel switched distributed configuration, there is a single set of the I/O
modules, but they can be addressed by both subsystems.
● In redundant operation: two-channel redundant configuration with maximum availability.
In the two-channel redundant configuration there are two sets of the I/O modules that can
be addressed by both subsystems.
Tools for configuring (STEP 7 - HW Config, PCS 7)
Like the S7-400, the CPU 410-5H Process Automation is also configured with STEP 7.
Restrictions for the configuration of the CPUs and the fault-tolerant system can be found in
the STEP 7 online help.
Detailed information on this can be found in the online help.
You can use PCS 7 and all the optional packages available there.
STEP 7 is the basis for configuring the PCS 7 process control system.
STEP 7 supports the various tasks involved in creating a project with the following project
views:
● Component view (HW Config)
● Process object view
● Technological perspective
The hardware that you need in a SIMATIC project, such as automation systems,
communication components, and process I/O, is stored in an electronic catalog. You
configure this hardware and assign the hardware parameters with HW Config.
