TAILIEUCHUNG - SIEMENS - SIMATIC Automation System S7-400H Fault-tolerant Systems

The first part of the description starts with the basic configuration of the fault-tolerant S7-400H programmable controller and the components making up the S7-400H base system. We then describe the hardware components with which you can expand this base system. The second part describes the software applications with which you can configure and program the S7-400H. In addition, a description is given of the additions and extensions, compared to the S7-400 standard system, that you will require for programming your user program in order to be able to react specifically to the properties of the S7-400H that enhance availability | SIEMENS SIMATIC Automation System S7-400H Fault-tolerant Systems Manual Preface Contents Fault-Tolerant Programmable Logic Controllers S7-400H Installation Options Getting Started Installation of a CPU 41x-H System and Operating Modes of the S7-400H Linking and Synchronizing Using I O on the S7-400H Communication Functions Configuring with STEP 7 Failure and Replacement of Components During Operation Modifying the System During Operation Synchronization module Technical Specifications 1 2 3 4 5 6 7 8 9 10 11 12 13 Edition 01 2004 A5E00068197-08 Appendices Characteristic Values of Redundant Programmable Logic Controllers Single Operation Converting from S5-H to S7-400H Differences Between Fault-Tolerant Systems and Standard Systems Function Modules and Communication Processors Used on the S7-400H Connection Examples for Redundant I O A B C D E F Glossary Index Safety Guidelines This manual contains notices intended to ensure personal safety as well as to protect the products and connected equipment against damage.
