3.6 Tools for configuration and programming
Like the S7-400, the S7-400H is also configured and programmed using STEP 7.
You only need to make allowances for slight restrictions when you write the user program.
However, there are some additional details specific to the fault-tolerant configuration. The
operating system automatically monitors the redundant components and switches over to the
standby components when an error occurs. You have already configured the relevant
information and communicated it to the system in your STEP 7 program.
Detailed information can be found in the online help, section Configuring with STEP 7
(Page 259), and Appendix Differences between fault-tolerant syste
ms and standard system
s
(Page 453).
Optional software
All standard tools, engineering tools and runtime software used in the S7-400 system are
also supported by the S7-400H system. Any restrictions in the functional scope are
described in the respective Online Help.
