New redundancy controllers for mid sized and large automation applications
Simple engineering just as with standard CPUs
Back-up CPU takes control of the process automatically and quickly – without data loss
Connection of field devices via Profinet ring
Siemens is expanding its Simatic S7-1500 Advanced Controller range with three new CPUs for redundant automation applications. The CPU1513R and CPU1515R are used for small to medium-sized projects with a focus on CPU redundancy. If one CPU fails, the back-up CPU automatically takes control of the process with no data loss and the process continues very quickly. As with the standard CPUs, the engineering of the redundancy CPUs is especially easy for users. The TIA Portal engineering framework and the redundant CPUs synchronize programs and data without the user having to intervene. The CPU1517H is used for larger applications and higher performance requirements. Here, dedicated synchronization modules enable faster, smooth switchover.
To increase the communication availability of the field devices, they are connected to the CPUs via a Profinet ring. All nodes are thus still accessible in the event of a fieldbus interruption. To enable this, the field devices, such as the Simatic ET 200SP distributed I/O system, must support S2 redundancy. In further steps, redundant Profinet networks will also be supported.
