Features:
- Bridge Between the 24 V DC Power Source and S7-300 Rack Backplane
- Integrates Central Processing Capability with Dual Interface Communication Support
- Functions Alongside the SIMATIC S7-300 Series Modules and PROFIBUS DP Networks
The SIEMENS 6ES7315-2AH14-0AB0 CPU Module serves as the Central Processing Unit in an S7-300 rack, delivering reliable program execution and data management to all modules within the system. It continuously processes automation logic through its 256 KB work memory while managing data exchange via the integrated MPI interface and the second DP master/device interface to ensure coordinated operation of all distributed I/O and function modules. Smooth communication handling is inherent with the 6ES7315-2AH14-0AB0, though utilizing a Micro Memory Card enables seamless program storage and expanded block capacity for sophisticated control applications. The 6ES7315-2AH14-0AB0 incorporates enhancements in multiple areas compared to earlier CPU generations, including the integration of dual communication interfaces within the S7-300 rack.
The 6ES7315-2AH14-0AB0 delivers essential control functions essential to the entire rack, forming a vital element of the automation pathway, directly influencing the proper, standard operation of the overall control system. One 6ES7315-2AH14-0AB0 CPU module is required per rack to serve as the central controller. The 6ES7315-2AH14-0AB0 occupies a single slot in the rack and is positioned in the designated CPU location.
For Distributed Control applications, the 6ES7315-2AH14-0AB0 CPU Module enables DP master/device operation through its secondary interface. Beyond conventional centralized processing, the distributed setup also facilitates automatic device handling. The 6ES7315-2AH14-0AB0 dual interface setup manages communication protocols using the internal architecture defined in the processor specifications. Through this approach, the distributed control architecture persistently tracks the status of connected DP devices. Should the system identify that a DP slave device has ceased providing reliable data transmission (exceeding configured communication thresholds), it will automatically register the diagnostic condition and record an entry in the diagnostic buffer for analysis.
The 6ES7315-2AH14-0AB0 SIEMENS CPU Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
