    System overview 4.3 S7-1500 R/H-CPUs S7-1500 R/H-CPUs The S7-1500R/H redundant system tolerates the failure of one of the two R- or H-CPUs. If the primary CPU fails, the backup CPU takes over control of the process as the new primary CPU at the point of the interruption.

    CPU and assumes control of the process as the primary CPU at the point of interruption. The switchover time can lengthen the cycle time. Reference The full technical specifications can be found in the manuals for the CPUs and on the Internet (https://mall.industry.siemens.com). 4.3.2 Redundancy Introduction In the following section you will get an overview how to achieve a higher network and plant availability in S7-1500R/H redundant systems.
  • Page 47 System overview 4.3 S7-1500 R/H-CPUs Communication relations in S7-1500R/H For a redundant system S7-1500R/H different IO device types are available. The IO device types differ with regard to the communication relations AR (Application Relation) they can establish to the CPUs of the redundant system: •...
  • Page 48 System overview 4.3 S7-1500 R/H-CPUs In addition, H-Sync forwarding forwards the synchronization data even during reconfiguration of the PROFINET ring. H-Sync forwarding avoids a cycle time increase if the PROFINET ring is interrupted. NOTE Support of H-Sync forwarding The technical specifications typically state whether a PROFINET device supports H‑Sync forwarding.
  • Page 49 System overview 4.3 S7-1500 R/H-CPUs The redundant S7-1500R system is in the RUN-Redundant system state. The PROFINET cable which directly connects the two CPUs fails. The PROFINET ring is interrupted. The PROFINET ring is being reconfigured. PROFINET devices without H-Sync forwarding do not forward any H-Sync frames during the reconfiguration time of the PROFINET ring.
  • Page 50 System overview 4.3 S7-1500 R/H-CPUs In a redundant system, an IO device with system redundancy S2 has a system redundancy AR with each of the two CPUs (IO controllers). An IO device thus supports ARs of two IO controllers simultaneously (for the same modules). A system redundancy AR can be either a primary AR or a backup AR.
  • Page 51 System overview 4.3 S7-1500 R/H-CPUs Unlike system redundancy S2, system redundancy R1 has a separate interface module for each of the two ARs. Due to these redundant interface modules, the availability is higher than with an S2 device. • Behavior in RUN-Redundant system state: The PROFINET communication runs on both system redundancy ARs simultaneously, each between one of the CPUs (IO controller) and an interface module of the R1 device.

MRP interconnection The MRP interconnection process is an enhancement of MRP and allows the redundant coupling of two or more rings with MRP in PROFINET networks. MRP interconnection is - like MRP - specified in the standard IEC 62439-2 (Edition 3).

    Decommissioning Introduction In the following section, you will find information on how to properly decommission individual components of your SIMATIC S7-1500R/H redundant system. Decommissioning is necessary when the component has reached the end of its service life. Decommissioning includes environmentally sound disposal and secure removal of all digital data of electronic components with storage medium.

    Decommissioning D.3 Recycling and disposal 2. Restore the factory settings of the CPU. We recommend resetting the CPU in STEP 7. When you reset a CPU to factory settings, select the options shown in the figure before the reset. Figure D-1  Resetting the CPU to factory settings NOTE If you reset the CPU using STEP 7 and you have selected the "Format memory card"...

    Glossary The AR (Application Relation) covers all communication relations between IO controller and IO device (for example IO data, data records, interrupts). Automation system Programmable logic controller for the open-loop and closed-loop control of process chains in the process engineering industry and in manufacturing technology. The automation system consists of different components and integrated system functions according to the automation task.
  • Page 376 Glossary Code block In SIMATIC S7, a code block contains part of the STEP 7 user program. Configuration Systematic arrangement of the individual modules (configuration). Connection plug The connection plug provides the physical connection between devices and the cable, for example. Consistent data Consistent data is data that belongs together in terms of content.
  • Page 377 Glossary Cyclic interrupt You will find further information in the glossary entry "Interrupt, cyclic". Data block Data blocks (DBs) are data areas in the user program that contain user data. Available data blocks: • Global data blocks that you can access from all code blocks. •...
  • Page 378 Glossary Distributed I/O Equipotential bonding Electrical connection (equipotential bonding conductor) that brings the conductive parts of electrical equipment and other conductive parts to the same or approximately the same potential. This prevents disruptive or dangerous voltages arising between these parts. Fail-safe systems Fail-safe systems (F-systems) are characterized by the fact that they remain in the safe state during the occurrence of specific failures or immediately transition into a different safe state.
  • Page 379 Glossary Ground Conductive ground whose electrical potential can be set equal to zero at any point. All interconnected, inactive parts of a piece of equipment. Ground Conductive ground whose electrical potential can be set equal to zero at any point. All interconnected, inactive parts of a piece of equipment.
  • Page 380 Glossary Interface module Module in the distributed I/O system. The interface module connects the distributed I/O system to the CPUs (IO controllers) via a fieldbus, and prepares the data of the I/O modules. Interrupt The operating system of the CPU distinguishes between various priority classes that control the execution of the user program.
  • Page 381 Glossary Isolated modules In the case of isolated input/output modules, the reference potentials of the control and load circuits are electrically isolated. Examples are optical isolators, relays or transformers. Input/output circuits can be connected to common potential. Load current supply The load current supply supplies the electric input and output circuits of the module.
  • Page 382 Glossary Parameter • Tag of a STEP 7 code block: • Tag for setting the behavior of a module (one or more per module). In as-delivered state, every module has an appropriate basic setting, which you can change by configuring in STEP 7.
  • Page 383 Glossary PROFINET PROcess FIeld NETwork, open Industrial Ethernet standard that continues PROFIBUS and Industrial Ethernet. A cross-manufacturer communication, automation, and engineering model defined by PROFIBUS International e.V. as an automation standard. PROFINET IO Communication concept for the realization of modular, distributed applications within the scope of PROFINET.
  • Page 384 Glossary Reference potential Potential from which the voltages of the circuits involved are observed and/or measured. Restart A warm restart deletes all non-retentive bit memory and resets non-retentive DB contents to the initial values from load memory. Retentive bit memory and retentive DB contents are retained.
  • Page 385 Glossary In the office setting and in automation engineering, devices from a wide range of vendors on the Ethernet support SNMP. You can operate SNMP-based applications on the same network in parallel to applications with PROFINET. The scope of supported functions varies depending on the device type. For example, a switch has more functions than a CP 1616.
  • Page 386 Glossary System IP address In addition to the device IP addresses of the CPUs, the redundant system S7‑1500R/H supports system IP addresses. You use the system IP addresses for communication with other devices (for example, HMI devices, CPUs, PG/PC). The devices always communicate over the system IP address with the primary CPU of the redundant system.
